Description
본 발명은 인화점이 높아진 건축재 표면도포용 수성 에멀젼 조성물에 관한 것으로서, 더 상세하게는, 알킬 알콕시 실란 및 흄드 실리카를 포함하는 조성물을 크림상의 안정한 형태로 존재하게 함으로써, 발수력과 침투성이 강할 뿐만 아니라 콘크리트의 탄산화에 의한 중성화 반응을 억제할 수 있는 건축재 표면 도포용 수성 에멀젼 조성물에 관한 것이다.The present invention relates to an aqueous emulsion composition for building surface coatings having a high flash point, and more particularly, by having a composition comprising alkyl alkoxy silane and fumed silica in a creamy stable form, not only having high water repellency and permeability. The present invention relates to an aqueous emulsion composition for building surface coating, which can suppress the neutralization reaction due to carbonation of concrete.
콘크리트와 같은 흡수성이 있는 재료는 물이 흡수될 경우, 동결 및 이산화탄소에 의한 중성화 반응 등에 의한 피해가 발생한다. 최근 이를 방지를 위하여 콘크리트 표면에 흡수 방지제를 사용하여 흡수에 의한 피해를 예방하고 있다. 원인 물질로는 대표적으로 모노머인 알킬 알콕시 실란을 주로 이용하며 실란은 콘크리트의 모세관을 소수정으로 전환시켜 동결 및 중성화 반응 등의 피해를 막아주는 재료이다. Absorbent materials such as concrete, when water is absorbed, cause damage due to freezing and neutralization by carbon dioxide. Recently, in order to prevent this, an absorption inhibitor is used on the concrete surface to prevent damage caused by absorption. As a causative agent, alkyl alkoxy silane, which is typically used as a monomer, is mainly used. Silane is a material that prevents damage such as freezing and neutralization by converting the capillary of concrete into hydrophobic wells.
그러나, 최근까지 개발된 흡수방지제는 인화점이 80℃ 보다 낮아 사용시 발생할 수 있는 화재에 취약하다는 단점이 있다. However, the absorption inhibitors developed until recently have a disadvantage in that the flash point is lower than 80 ° C. and therefore vulnerable to fire that may occur when used.
예를 들어, 대한민국 특허출원 제1996-0017215호, "알킬 알콕시 실란의 수성 에멀젼, 그 제조방법 및 이를 함유하는 침수 흡수방지제”는 원인 물질로써 알킬 알콕시 실란 중 알킬의 크기가 4~8개인 것을 사용하고 있으나, 이 경우 인화점은 약 64℃정도이며 화재에 취약할 뿐만 아니라 여름철 건축물의 옥상 슬래브의 표면온도가 약 65~75℃임을 감안할 경우 매우 위험할 수 있다.For example, Korean Patent Application No. 1996-0017215, "Aqueous Emulsion of Alkoxy Alkoxy Silane, Method for Producing It, and Immersion Absorption Agent Containing the Same" is used as a causative agent of 4 to 8 alkyl in alkyl alkoxy silane. However, in this case, the flash point is about 64 ℃ and not only vulnerable to fire, but also can be very dangerous considering that the surface temperature of the rooftop slab of summer buildings is about 65 ~ 75 ℃.
상기 특허에서는 알킬 알콕시 실란을 이용하고 그 입자의 크기가 0.5~10㎛이며 실란의 농도가 5~70중량%인 수용화 방법을 제시하고 있으나 동일하게 위험성이 있다. 현재 “한국산업표준번호 KS F 4930, 콘크리트 표면 도포용 액상형 흡수방지제”에서 제시된 흡수방지제는 콘크리트 등의 무기질 구조물에 도포시 침투 후 고분자화 반응에 의하여 모세관 내에서 발수력을 발생시켜 흡수를 차단하는 원리를 이용한 것으로서, 인화점은 80℃일 것을 명시하고 있다. The patent uses an alkyl alkoxy silane, and the particle size is 0.5 ~ 10㎛ and the concentration of the silane is 5 to 70% by weight of the water-soluble method, but there is a risk. At present, the absorption inhibitor proposed in “Korea Industrial Standard No. KS F 4930, Liquid-type Absorption Agent for Concrete Surface Coating” is applied to inorganic structures such as concrete and penetrates into the water to generate water repellency in the capillary. Using the principle, the flash point specifies that it is 80 ° C.
본 발명은 상기의 문제점을 해소하기 위하여, 액상형 흡수방지제로서의 성능을 유지하면서도 인화점이 향상된 건축재 표면도포용 수성 에멀젼 조성물을 제공하는 것을 목적으로 한다.

The aqueous emulsion composition for building surface coating according to the present invention for achieving the above object is 75 to 90% by weight of the alkyl alkoxy silane mixture, 1 to 10% by weight of fumed silica, 0.1 to 3% by weight of the emulsifier, and the residual amount relative to the weight of the total composition Contains water.
본 발명의 알킬 알콕시 실란 혼합물은 탄소수 8~9인 제1 알킬 알콕시 실란과, 탄소수 10~14인 제2 알킬 알콕시 실란의 2종이 혼합된 것을 이용하는 데 특징이 있다. 이와 같이 2종의 알킬 알콕시 실란을 이용함으로써 흡수방지제로서의 성능을 유지하면서도 인화점 80℃ 이상을 확보할 수 있다. The alkyl alkoxy silane mixture of the present invention is characterized by using a mixture of two kinds of a first alkyl alkoxy silane having 8 to 9 carbon atoms and a second alkyl alkoxy silane having 10 to 14 carbon atoms. By using two kinds of alkyl alkoxy silanes as described above, a flash point of 80 ° C. or more can be ensured while maintaining the performance as an absorption inhibitor.
바람직한 예에서, 상기 제1 알킬 알콕시 실란은 n-옥틸 에톡시 실란이고, 상기 제2 알킬 알콕시 실란은 데실 트리 에톡시 실란일 수 있다. 또한, 바람직하게는 상기 알킬 알콕시 실란은 3개의 관능기를 포함하는 알킬 트리알콕시 실란일 수 있다.

Also, preferably, the alkyl alkoxy silane may be an alkyl trialkoxy silane including three functional groups.

본 발명은 건축재 표면의 보호를 목적으로 표층부에 도포하여 함침시킴으로써, 흡수방지층을 형성하는 건축재 표면 도포용 수성 에멀젼에 관한 것이다. 본 발명이 적용되는 상기 건축재는, 예를 들면, 콘크리트, 시멘트 모르타르, ALC 패널, 석면 슬레이트, 벽돌, 석재 등이고, 여기에 한정되지 않는다.The present invention relates to an aqueous emulsion for building surface coating which forms an absorption prevention layer by applying and impregnating a surface layer for the purpose of protecting the surface of building material. The building material to which the present invention is applied is, for example, concrete, cement mortar, ALC panel, asbestos slate, brick, stone, or the like, but is not limited thereto.
알킬 알콕시 실란을 이용하는 콘크리트 표면 도포용 액상형 흡수방지제는 크게 유성과 수성으로 구분된다. 유성의 경우 보통 끓는점이 110~140℃정도인 솔벤트와 혼합하여 사용되며 또 다른 용제로써 이소프로필 알콜이 사용된다. 그러나 이러한 경우 콘크리트가 벽체 등으로 흘러내려 고른 침투 성능을 확보하기는 어렵다.Liquid absorbents for coating concrete surfaces using alkyl alkoxy silanes are largely divided into oil and water. In the case of oily oil, it is usually mixed with solvent having boiling point of 110 ~ 140 ℃ and isopropyl alcohol is used as another solvent. However, in such a case, it is difficult to secure even penetration performance because concrete flows down to a wall or the like.
그러나, 알킬 알콕시 실란을 수용화하여 크림상으로 제조한 경우, 이미 알려진 바와 같이 대기 중의 수분과 반응하여 실란올로 전환된 후 고분자화 되어 콘크리트 내부에 발수 특성을 부여하여 벽체에서 흘러내리지 않고 흡수방지를 효과적으로 획득할 수 있다. 또한, 깊숙이 침투하여 고분자화 되는 함침에 의하여 호흡효과(Breathing Effect)를 갖게 하여 도포 후 콘크리트의 강도 증진에 효과적이다.However, when the alkyl alkoxy silane is prepared in a cream form, it is known to react with moisture in the air to be converted into silanol and then polymerized to impart water repellent properties to the interior of concrete to prevent absorption without falling off walls. Can be effectively obtained. In addition, it is effective to increase the strength of concrete after application by having a breathing effect (Breathing Effect) by the impregnation that penetrates deep and polymerized.
본 발명은 알킬 알콕시 실란을 수용화한 수성 에멀젼으로서 전체 조성물 중량 대비 알킬 알콕시 실란 혼합물 약 70~90 중량%, 흄드 실리카 약 1 ~ 10 중량%, 유화제 약 0.1 ~ 3 중량%, 및 잔류량의 물을 포함한다.
The present invention is an aqueous emulsion containing an alkyl alkoxy silane, which is about 70 to 90% by weight of an alkyl alkoxy silane mixture, about 1 to 10% by weight of fumed silica, about 0.1 to 3% by weight of an emulsifier, and a residual amount of water, based on the total weight of the composition. Include.
이하 본 발명에 따른 조성물의 각 성분을 상세하게 살펴본다. Hereinafter, each component of the composition according to the present invention will be described in detail.
본 발명은 알킬 알콕시 실란과 흄드 실리카를 포함하는 수성 에멀젼으로서, 알킬 알콕시 실란에 의한 뛰어난 발수 효과는 물론이고, 흄드 실리카가 포함되어 있어서 콘크리트 모세관내에서의 수산화칼슘과의 반응에 의해서 결정을 성장시켜 콘크리트의 기공을 막아줌으로 해서 방수 효과까지 가지고 있다. 따라서, 물 뿐만 아니라 콘크리트의 탄산화에 의한 중성화 반응을 억제할 수 있고, 염화물 이온, 산성액 등의 외부환경으로부터 콘크리트 등의 건축재를 보호할 수 있다.The present invention is an aqueous emulsion containing alkyl alkoxy silane and fumed silica, as well as excellent water-repellent effect by alkyl alkoxy silane, containing fumed silica, so that the crystals grow by reaction with calcium hydroxide in the concrete capillary By blocking the pores of the water has a waterproof effect. Therefore, neutralization reaction by carbonation of concrete as well as water can be suppressed, and building materials, such as concrete, can be protected from external environments, such as chloride ion and an acid solution.
상기 흄드 실리카는 콘크리트중의 수산화 칼슘과의 반응; Ca(OH)2 + SiO2 → CaO·SiO2·H2O 경로를 거쳐 고분자화와 결정화 반응을 일으켜 콘크리트 중의 모세관을 밀봉함으로써 흡수방지 능력과 공기의 입출입을 막아 발수성과 방수성을 모두 획득할 수 있다. 이는 이미 잘 알려져 있는 반응이나 최근까지 흄드 실리카가 높은 비표면적에 의하여 콘크리트에 적용할 경우 물-시멘트비를 상승시켜 크게 도움이 되지 않으나, 본 발명에서와 같이 함침 재료로 사용할 경우 입경이 매우 작아 흄드 실리카가 콘크리트 모세관으로 쉽게 이동할 수 있다는 이론에서 착안하였다. The fumed silica is reacted with calcium hydroxide in concrete; Ca (OH) 2 + SiO 2 → CaO · SiO 2 · H 2 O It can polymerize and crystallize through the path to seal the capillary in concrete, preventing water absorption and entering / exiting air, thereby obtaining both water repellency and water resistance. have. This is a well-known reaction or until recently fumed silica is applied to concrete by the high specific surface area, it does not help greatly increase the water-cement ratio, but when used as an impregnating material as in the present invention, the fumed silica is very small It was conceived in the theory that can easily move to concrete capillary.
상기 흄드 실리카는 약 5 ~ 20㎛의 입자크기를 갖는 것이 바람직하며, 입자의 크기가 20㎛ 보다 클 경우 크림상은 2층으로 분리되어 사용할 수 없으며 흄드 실리카가 사용되지 않거나 적정량보다 적을 경우 방수성이 발생하지 않는다. Preferably, the fumed silica has a particle size of about 5 to 20 μm, and when the particle size is larger than 20 μm, the cream phase cannot be separated into two layers and water resistance is generated when the fumed silica is not used or is less than the appropriate amount. I never do that.
본 발명의 주요한 특징 중의 하나는 탄소수가 서로 다른 2종의 알킬 알콕시 실란을 혼합한 혼합물을 사용한다는 점이다. 일반적으로 건축재 표면도포용 수성 에멀젼 조성물에 사용되는 알킬 알콕시 실란에서 알킬의 탄소수가 증가할수록 침투 깊이가 작아지는 단점이 있다. 그러나, 본 발명자들은 알킬의 탄소수를 8~14로 제한할 경우 인화점은 증가하고 침투깊이가 달라지지 않음을 발견하여 이를 적용한 결과를 우수한 흡수방지 및 차수 특성을 확인하였다. 이때 탄소수가 8보다 작은 경우 인화점이 80℃보다 낮아 규격에 적합하지 않으며 다른 유기 화합물을 사용할 경우 인체에 유해하다. 탄소수가 14개보다 클 경우 침투성이 저조하고 가격이 매우 높다는 단점이 있다. 한편, 관능기가 메톡시인 경우 반응 후 메탄올이 발생하여 인체에 유해성이 클 수 있다. 그러므로 본 발명에서는 탄소수가 서로 다른 2종의 알킬 알콕시 실란을 혼합하여 발수 및 콘크리트의 탄산화에 의한 중성화 반응을 억제하는 작용을 유지하면서도 인화점을 적절하게 조절함으로써 화재의 위험성을 감소시킨다. One of the main features of the present invention is the use of a mixture of two alkyl alkoxy silanes having different carbon numbers. In general, the alkyl alkoxy silane used in the aqueous emulsion composition for building surface coating has a disadvantage in that the penetration depth decreases as the number of alkyl carbons increases. However, the present inventors found that the flash point is increased and the penetration depth does not change when the carbon number of the alkyl is limited to 8 to 14, and the result of applying the same confirms excellent absorption prevention and order characteristics. At this time, if the carbon number is less than 8, the flash point is lower than 80 ° C, which does not meet the standard, and it is harmful to the human body when other organic compounds are used. If the carbon number is larger than 14, the penetrability is low and the price is very high. Meanwhile, when the functional group is methoxy, methanol may be generated after the reaction, and thus may be harmful to the human body. Therefore, in the present invention, two kinds of alkyl alkoxy silanes having different carbon numbers are mixed to reduce the risk of fire by appropriately adjusting the flash point while maintaining the action of inhibiting the neutralization reaction by water repellent and carbonation of concrete.
하나의 바람직한 예에서 본 발명에서는 우수한 흡수방지제의 특성이 있는 알킬 알콕시 실란 중 탄소수 8~9인 제1 알킬 알콕시 실란과, 탄소수 10~14인 제2 알킬 알콕시 실란의 2종이 혼합된 것을 이용하여 콘크리트의 모세관의 표면 장력을 작게 함으로써 흡수방지 기능을 확보하고 인화점을 높인다. In one preferred embodiment, in the present invention, concrete is prepared by mixing two kinds of the first alkyl alkoxy silane having 8 to 9 carbon atoms and the second alkyl alkoxy silane having 10 to 14 carbon atoms among the alkyl alkoxy silanes having excellent anti-absorption properties. By reducing the surface tension of the capillary tube, the absorption function is ensured and the flash point is increased.
상기 제1 알킬 알콕시 실란은 예를 들어, n-옥틸 트리 에톡시 실란, I-부틸 트리에톡시 실란, I-부틸 트리 메톡시 실란, n-옥틸 트리 메톡시 실란 등을 들 수 있다. 바람직하게는 n-옥틸 트리 에톡시 실란을 사용하는 것이 좋다.Examples of the first alkyl alkoxy silane include n-octyl triethoxy silane, I-butyl triethoxy silane, I-butyl trimethoxy silane, n-octyl trimethoxy silane, and the like. Preference is given to using n-octyl triethoxy silane.
상기 제2 알킬 알콕시 실란은 예를 들어, 데실 트리 에톡시 실란, 데실 트리 메톡시 실란 등을 들 수 있으며 바람직하게는 데실 트리 에톡시 실란이 좋다.Examples of the second alkyl alkoxy silane include decyl triethoxy silane, decyl trimethoxy silane, and the like, preferably decyl triethoxy silane.
본 발명의 일 실시예에서는 3 관능기로 구성된 n-옥틸 트리에톡시 실란(octyl ethoxy silane)과 데실 트리에톡시 실란이 이용되었다. In one embodiment of the present invention, n-octyl ethoxy silane and decyl triethoxy silane composed of trifunctional groups were used.
상기 알킬 알콕시 실란 혼합물에서 상기 제2 알킬 알콕시 실란의 혼합비가 클수록 인화점이 높아지는 장점이 있지만, 그 함량이 일정 이상이 되면 침투성이 낮아지는 단점이 있으므로 제1 알킬 알콕시 실란과 제2 알킬 알콕시 실란의 혼합비(중량비)는 바람직하게는 약 9:1 ~ 7:3이며, 더욱 바람직하게는 약 8.5:1.5 ~ 7.5:2.5이다. The mixing ratio of the second alkyl alkoxy silane in the alkyl alkoxy silane mixture has the advantage that the flash point is higher, but the penetrability is lowered when the content is more than a certain amount, so the mixing ratio of the first alkyl alkoxy silane and the second alkyl alkoxy silane The weight ratio is preferably about 9: 1 to 7: 3, more preferably about 8.5: 1.5 to 7.5: 2.5.
상기 유화제는 특별히 한정한 것은 아니나, 지방산염, 알킬 황산에테르염, 알킬알릴 술폰산염, 알킬 인산 에테르염 등의 음이온성 유화제와 폴리옥시에틸렌 화합물, 소르비톨 화합물, 솔비탄 화합물, 실리콘 화합물로 이루어진 비이온성 유화제를 포함한다. 또한 양이온성 유화제로는 4차 암모늄염 화합물과 양쪽성 유화제로써 레시틴 화합물을 포함한다. 이들 유화제는 단독 또는 혼합하여 사용할 수 있다.The emulsifier is not particularly limited, but anionic emulsifiers such as fatty acid salts, alkyl sulfate ether salts, alkylallyl sulfonates and alkyl phosphate ether salts, and nonionics made of polyoxyethylene compounds, sorbitol compounds, sorbitan compounds and silicone compounds Emulsifiers. In addition, cationic emulsifiers include quaternary ammonium salt compounds and lecithin compounds as amphoteric emulsifiers. These emulsifiers can be used individually or in mixture.
상기 유화제의 사용량이 클 경우 수분 흡수 능력이 급격히 감소하여 흡수 방지제로써의 효과가 없어지게 되며 유화제의 종류에 따라 다르나 사용량은 3% 이내여야 한다. 또한 알킬 알콕시 실란의 함량은 높을수록 좋은 효과가 있으며 70% 미만으로 만들어진 경우 콘크리트에서의 발수층의 형성이 나빠 효과가 없을 수 있다. If the amount of the emulsifier is large, the water absorption capacity is drastically reduced, so that the effect as an anti-absorption agent is lost. In addition, the higher the content of the alkyl alkoxy silane has a better effect, and if made of less than 70% may be ineffective in the formation of a water-repellent layer in concrete.
본 발명의 수성 에멀젼 조성물은, 물에서 알킬 알콕시 실란 방울의 직경이 2~10㎛인 에멀션을 형성하기에 충분한 조건하에서 에멀션화 및 분산기를 사용하여 알킬 알콕시 실란, 물, 유화제 및 임의의 다른 첨가제를 에멀션화하여 얻을 수 있다. 상기 방울의 직경은 에멀션화 및 분산기를 선택하여 그리고 교반속도, 노즐로부터의 방출 압력, 에멀션화 시간 등과 같은 에멀션화 조건을 조절함으로써 조절할 수 있다. The aqueous emulsion composition of the present invention may be prepared using an emulsifier and a disperser under conditions sufficient to form an emulsion having an alkyl alkoxy silane drop of 2-10 μm in diameter in water to form an alkyl alkoxy silane, water, emulsifier and any other additives. It can be obtained by emulsifying. The diameter of the drop can be adjusted by selecting the emulsification and disperser and by adjusting the emulsification conditions such as stirring speed, discharge pressure from the nozzle, emulsification time and the like.
본 발명의 일 예에서, 알킬 알콕시 실란 혼합물 약 70~90 중량%, 흄드 실리카 약 1 ~ 10 중량%, 유화제 약 0.1 ~ 3 중량%, 및 잔류량의 물을 혼합한 후 3,000rpm 이상의 고속 교반기에서 혼합하여 크림상을 형성한다. In one embodiment of the present invention, about 70 to 90% by weight of the alkyl alkoxy silane mixture, about 1 to 10% by weight of the fumed silica, about 0.1 to 3% by weight of the emulsifier, and the residual amount of water are mixed in a high speed stirrer of 3,000 rpm or more. To form a creamy form.
제조된 알킬 알콕시 실란 크림은, 콘크리트 등의 무기 흡수 재질의 구조물에 도포할 경우, 응집에 의하여 투명하게 변화하면서 알킬 알콕시 실란은 콘크리트의 모세관으로 흡수 침투된 후, 알킬 알콕시 실란은 탈수 반응을 거쳐 실리콘 폴리머로 전환하게 되어 발수성으로 변화하며 콘크리트의 모세관의 표면을 소수층으로 개질한다. 제조시 교반 속도가 작아 크림의 점도가 낮을 경우 에멀전상이 얻어지며 이때는 수 시간 또는 수십일 이내에 층 분리가 발생하여 성능의 저하가 발생하거나 중합되어 성능이 발휘되지 않는다. When the prepared alkyl alkoxy silane cream is applied to a structure made of inorganic absorbent material such as concrete, the alkyl alkoxy silane absorbs and penetrates into the capillary of concrete while being transparently changed by agglomeration, and then the alkyl alkoxy silane undergoes dehydration reaction. It converts into a polymer and becomes water repellent and modifies the surface of concrete capillary to a hydrophobic layer. When the stirring speed is low during manufacture, the viscosity of the cream is low, an emulsion phase is obtained. In this case, a layer separation occurs within several hours or several tens of days, resulting in deterioration of performance or polymerization, thereby not exhibiting performance.

하기 표 1과 같은 중량으로 하여 알킬 알콕시 실란 혼합물 1용액을 물과 계면활성제 2용액에 서서히 떨어뜨리면서 3,000rpm 이상으로 고속 교반하여 알킬 알콕시 실란에멀젼 크림을 제조하였다. 이때, 알킬 알콕시 실란 혼합물은 n-옥틸 에톡시 실란:데실 트리 에톡시 실란 = 8:2(중량비)로 혼합한 혼합물이며, 2 용액의 유화제로는 솔비톨 지방산 에테르가 사용되었다. 제조된 에멀전 크림의 콘크리트에서의 성능은 표 2와 같다.The alkyl alkoxy silane emulsion cream was prepared by rapidly stirring the alkyl alkoxy silane mixture 1 solution at a weight as shown in Table 1 to 3,000 rpm or more while slowly falling into the water and the surfactant 2 solution. At this time, the alkyl alkoxy silane mixture was a mixture of n-octyl ethoxy silane: decyl triethoxy silane = 8: 2 (weight ratio), and sorbitol fatty acid ether was used as an emulsifier of two solutions. The performance of the prepared emulsion cream in concrete is shown in Table 2.

하기 표 3은 표 1의 알킬 알콕시 실란 중 데실 트리 에톡시 실란의 중량비를 바꾸어 제조한 경우의 침투 깊이와 인화점, 흡수비의 성능을 “한국산업표준번호 KS F 4930, 콘크리트 표면 도포용 액상형 흡수방지제”에 의거하여 데실 트리 에톡시 실란이 사용되지 안은 것과 비교한 것이다. Table 3 shows the performance of penetration depth, flash point, and absorption ratio when the weight ratio of decyl triethoxy silane in the alkyl alkoxy silane of Table 1 was changed to “Korean Industrial Standard No. KS F 4930, Liquid Absorption Agent for Concrete Surface Coating”. On the basis of the decyl triethoxy silane is used.
데실 트리 에톡시 실란이 15 중량% 이용된 경우 인화점은 81℃로 측정되었으며 20중량%가 이용된 경우 87℃로 확인되었다. 또한 침투 깊이나 흡수비는 모두 데실 트리 에톡시 실란이 사용되지 않은 것과 비교하여 나빠지지 않았다. 그러므로 사용된 데실 트리 에톡시 실란은 알킬 알콕시 실란 중 15 중량% 이상이며 바람직하게는 15~25 중량%이다.
The flash point was measured at 81 ° C. when 15% by weight of decyl triethoxy silane was used, and 87 ° C. when 20% by weight was used. In addition, both penetration depth and absorption ratio did not deteriorate as compared with those without decyl triethoxy silane. The decyl triethoxy silane used is therefore at least 15% by weight and preferably 15-25% by weight in the alkyl alkoxy silane.
