Definitions
- the present invention relates to compositions containing a binder which contains at least one alkoxy-functional polysiloxane, and at least one crosslinking catalyst, wherein the crosslinking catalyst is a silicon-containing guanidine compound, and optionally contains an alkoxysilane crosslinker.
- silicone resin compositions have long been known as binders which can be cured by means of a hydrolysis and condensation mechanism. This usually takes place with catalysts which promote the hydrolysis and / or condensation process of the curable groups.
- High-temperature applications based on a purely physical drying principle usually require baking of the paint film at elevated temperatures in order to achieve the necessary chemical and physical resistance. This is particularly disadvantageous because not all materials can be forced dried due to the limiting furnace size. Furthermore, as object size increases, it becomes more and more difficult to achieve an object temperature of typically 150-250 ° C required for the stoving process. For applications where curing at room temperature is desired, special demands are placed on the catalyst. This is the case in particular if short curing times are desired in order to ensure rapid further processing of the coated objects.
- Mono-, oligo- or polymers carrying alkoxysilyl groups can be prepared by various reactions, so not only are polyurethanes bearing alkoxysilyl groups, polyesters, polyethers, polyacylates but also a large number of other polymers known. Furthermore, polymers are known which from the hydrolysis of Alkoxy functions recoverable silanols carry. Such compounds may in turn be silane-based or else with pronounced semi-organic or inorganic polymer character, for example as in the poly (dimethyl) siloxane-ols (PDM siloxanes) or the silicone resins.
- PDM siloxanes poly (dimethyl) siloxane-ols
- WO 2009/106720 discloses metal sulfonates and fluoroalkylsulfonates as polycondensation catalysts which cure organopolysiloxane compositions to siloxane elastomers.
- Such catalysts have the great disadvantage that, in addition to limited availability and high price, they can not be used in the presence of basic components such as amines or basic fillers (e.g., chalks).
- basic components such as amines or basic fillers (e.g., chalks).
- liquid or free-flowing catalysts if possible still without intrinsic coloration as well as in the form of a 100% active substance, would be as far as possible preferred in the end applications.
- WO 2010/1 17744 discloses the use of superbasic phosphazene catalysts for the condensation of PDM-OH siloxanes.
- these show an unfavorable toxicological profile, are uneconomical and therefore can not be used in a large number of applications or require costly separation or aftertreatment.
- Toxicologically safer catalyst preparations such as e.g. Metal carboxylates in combination with amine compounds such as.
- amine compounds such as.
- EP 1445287 As described in EP 1445287 (US 2004/198885), show an insufficient curing rate of the local binder matrix of up to 5 days. Such long curing times are generally unacceptable for the majority of applications as well.
- titanates or titanium complexes have also shown activity, which, however, depending on the use concentration, cause strong yellowing of the curing compounds and, in some cases, also lead to incompatibilities with other components present in the hardening composition, e.g. Show amines.
- the use of titanates to cure silicone resin binders is described i.a. in EP 1 174467 (US 2002/028296) and DE 19934103 (US 2003/068506).
- Another significant disadvantage of metal alkoxides is their strong hydrolysis lability, which is accompanied by decreasing catalytic performance.
- organotin compounds are well known, but are increasingly critically evaluated toxicologically.
- the use of organotin compounds is therefore very controversial, especially because this was imposed by the amendment of EU Directive 76/769 EEC of 28.05.2009 restrictions.
- organotin compounds for curing siloxanes or siloxane resin binders in particular can be found inter alia in DE 10319303 (US 2004/220331) and WO9412586 (US5275645). It is therefore to be expected that also tin salts will be assessed more toxicologically more critically in the future.
- tin carboxylates can also be used as curing catalysts, as WO 0056817 (US Pat. No. 6,703,442) shows.
- EP1563822 discloses inter alia the use of so-called superbases, for example cyclic amidines (DBU), for curing dental materials in which short curing times are desired.
- DBU cyclic amidines
- WO2009 / 047580 discloses the use of a mixed catalyst system consisting of a tin compound and an organoguanidine for curing compositions containing long-chain linear siloxane diols, alkoxysilane crosslinkers, fillers and aminosilanes.
- This type of catalysis has the defect that it is not entirely tin-free and is transferable to a broad silicone resin base.
- the present invention therefore relates to compositions comprising as component (a) a binder which comprises at least one alkoxy-functional polysiloxane, and as component (b) at least one crosslinking catalyst which is a silicon-containing guanidine compound as described in the claims.

- Another object of the present invention is a method for curing compositions comprising as component (a) a binder containing at least one alkoxy-functional polysiloxane, and as component (b) at least one crosslinking catalyst as described in the claims which is carried out at room temperature.
- An advantage of the method is that no forced drying is necessary for curing the alkoxy-functional polysiloxanes and thus an energy saving is connected.
- this is a disadvantage for large components, for the corresponding drying systems are difficult to realize, e.g. Aircraft or turbine parts, overcome.
- compositions according to the invention are decompose without residue in high-temperature applications of the coated components or at least the residues are compatible with the binder film and thus a perfect surface is maintained.
