Abstract

A surface enhancement formulation which is an oil-in-water emulsion comprising at least 95% by weight water and an emulsified phase comprising 0.1-2% by weight of an amino functional polysiloxane, which is polymerisable in air on evaporation of the water. The composition further comprisies 0.05-1% by weight water soluble drying retarding agent and 0.5-3% by weight of a water soluble solvent (in which both the amino-functional polysiloxane and the drying retarding agent are soluble). Preferred drying retarding agents include glycols such as butyldiglycol, propylene glycol, ethylene glycol and butyl glycol. A preferred solvent is isopropanol. Concentrates for dilution to produce the formulation and a method for the production of the formulation are also outlined. The formulation is particularly useful for application to painted metal or painted plastics surfaces, e.g. car bodywork. When applied the formulation provides good gloss characteristics and pronounced beading of water applied to the surface.

Description

<p>SURFACE ENHANCEMENT FORMULATION</p>
<p>The present invention relates to formulations intended for use in treating a surface to enhance the properties thereof. Such formulations are referred to herein as "surface enhancement formulations". The invention relates particularly, hut by no means exclusively, to such formulations that are intended for use in treating a painted metal or painted plastics surface, e.g. on the exterior of a car or other motor vehicle. Specific examples of such surfaces are the painted metal bodywork of a vehicle or painted plastics bumpers or mirror casings (so-called "mirror backs").</p>
<p>Many motor vehicle owners take a pride in the appearance of the bodywork of their vehicle. To this end, the vehicle will be washed periodically to remove soiling material (e.g. dust or mud) deposited from the environment in which the vehicle is driven. Additionally the bodywork is generally also polished to enhance the appearance.</p>
<p>Polishing also has the effect that water deposited on the bodywork (e.g. as a result ofrain or condensation) tends to become "beaded" on the bodywork surface. This is contrast to unpolished vehicle bodywork for which such water tends to form a film and give a rather "flat" appearance to the bodywork. The beaded appearance is regarded by many vehicle owners as having some aesthetic value.</p>
<p>According to the present invention there is provided a surface enhancement formulation which is an oil-in-water emulsion comprising at least 95% by weight water and an emulsified phase containing 0.1 to 2% by weight of an amino functional polysiloxane which is polymerisable in air on evaporation of water, said composition further containing 0.05 to 1% by weight of a water soluble drying retarding agent and 0.5- 3% by weight ofa water soluble solvent ln which the amino functional polysiloxane and drying retarding agent are soluble, all percentages being based on the total weight of the formulation.</p>
<p>The formulation in accordance with the invention may he applied to a painted metal or plastics surface (particularly, hut not exclusively, on the exterior of a motor vehicle) to provide a protective coating on the surface (examples of such surfaces are given above). More particularly, the coating is formed as a result of evaporation of water and polynierisation in air of the amino functional polysiloxane. The formulation maybe applied to the surface by means of a cloth (e.g. a micro-fibre cloth) that is rubbed over the surface to spread the formulation. The presence of the drying retarding agent causes slower evaporation of water (than would otherwise be the case if the agent were not present) allowrng time for the formulation to be "worked" over the surface.</p>
<p>The resulting coating provides a number ofhenefts. Firstly, the coating provides for a greater degree of "beading" of water deposited on the surface (e.g. by rain or condensation) than is the case with many conventional polishes. Therefore the aesthetic appearance ofcar bodywork (which has water deposited thereon) is enhanced. Secondly the applied coating can provide a higher gloss level than many conventional polishes.</p>
<p>Thirdly the coating lasts longer than many conventional polishes. Fourthly there maybe a reduced tendency of soiling material (e.g. dust or mud) to adhere to the painted bodywork thus making cleaning (by washing) easier.</p>
<p>The emulsified phase may be in the form of micelles and/or have an average droplet size of less than 1,000 nrn (nanometres), more preferably less than 500 nm (nanornetres), even more preferably less than 100 nm (nanometres) and still more preferably less than 50 nm, and most preferably less than 20 nm. The average droplet size may for example be about 10 nm.</p>
<p>The amino functional polysiloxane should be one that is film fonning to provide (alter polymerisation) a coating in the form of a lacquer and is preferably present in an niciint ni( _1 / hv x,pi uh ind rnruzt rre1er2h1\I 2hrl11 (1 S_i (I / by weoht o l-,-i ii -. .J.. . ., . . . .J..</p>
<p>0.9% by weight (based on the total weight of the formulation).</p>
<p>The amino functional polysiloxane may be one which undergoes linear polymcrisation in air (as opposed to cross-linking).</p>
<p>The amino functional polysiloxane may, for example, having a molecular weight of 40,000-60,000, more preferably about 45,000-55,000, e.g. about 50,000.</p>
<p>A particularly suitable amino functional polysiloxane is an amino functional polydirnethylsi loxane.</p>
<p>A particularly suitable amino functional poly-dimethylsiloxane is available under the designation BC 93/075 from Basildon Chemical Company Ltd. The product chain extends through reactions of SiOMe -SiOH condensation and SiOH -SiOH condensation.</p>
<p>Preferably the drying retarding agent is present in the formulation in an amount of 0.1 to 0.3% by weight, e.g. about 0.2% by weight.</p>
<p>A particularly suitable drying retarding agent is butyldiglycol. Further examples include monopropylene glycol, monoethylene glycol and butyl glycol.</p>
<p>The amount of water soluble solvent will generally he in the range of 1-2% by weight, e.g. about 1.5%.</p>
<p>A particularly suitable water soluble solvent is iso-propanol. Further examples include ethanol and methanol.</p>
<p>A surface active agent will generally be present to maintain the emulsified phase.</p>
<p>The amount of the surface active agent will generally he in the range of 0.01 to 1% by ud-'inh1t rf th frrtnii1qtinn Thc' ciirfirp rtiv unt be i ncn_rnip QllrIcu'c' 1iuc' agent, e.g. as a available under the designation Berol 048 as available from Akzo Nobel.</p>
<p>Formulations in accordance with the invention may be prepared by the steps of (i) producing an organic phase by dissolving the amino functional polysiloxane and drying retarding agent in the organic solvent; (ii) producing an acidified aqueous phase containing the surface active agent; (iii) homogenising the organic phase with the aqueous phase to produce a concentrate comprising, by total weight of the concentrate, 40-80% by weight of water, 1-20% by weight ofthe amino functional polysiloxane as an emulsified phase, 0.5-10% by weight of the drying retarding agent, and 5-30% by weight of the organic solvent; and (iv) diluting the concentrate with water to produce the final formulation.</p>
<p>The aqueous phase (ii) comprises water, a surface active agent (e.g. as described above) and an acidifying agent to give the aqueous phase a preferred pH of 4 to 6 since at a pH of greater than 6 the amino functional polysiloxanc may not form an emulsified phase during subsequent steps of the process (see below). The preferred pH of the aqueous phase is 4 to 5. Most preferably the acidifying agent is an organic acid, particularly acetic acid.</p>
<p>The oil and aqueous phases ((I) and (ii) respectively) may then he homogenised using a high speed homogeniser to produce the concentrate (iii) which may subsequently 1-i;lt-l 17;t1, Mntc'r tim nrnri,icn ti-ic' 1'nni nrn-. ,.intirn (-r\ &/ 4 ii t.4Lj VYILSI WV LtL'.L LV.J.JL SLLd'.d Li I/ LiIiI I JI Ii LLLJULLJLI i V J.
