Method for Controlling the Crosslinking Time for a Silicone Gel That Gives Off a Volatile Organic Substance

Abstract

The present invention relates to a method for preparing a silicone gel that gives off a volatile organic substance, the method comprising the following steps: 1) providing a part A comprising (i) from 10% to 89.99% by weight of a dihydroxy PDMS polymer that has a viscosity measured at 25° C. of between 3000 and 100,000 cSt (mm2/s) and (ii) from 10% to 90% by weight of a mixture including a volatile solvent capable of solubilising the dihydroxy polydimethylsiloxane polymer and a volatile organic substance; 2) providing a part B comprising (iii) from 10% to 30% by weight of MMT and (iv) from 70% to 90% by weight of a non-functionalised polydimethylsiloxane silicone oil that has a viscosity measured at 25° C. of between 10 and 245 cSt (mm2/s) capable of solubilising N-morpholinomethyl triethoxysilane; 3) preparing a mixture comprising from 95% to 99% by weight of part A and from 1% to 5% by weight of part B; characterised in that part A also comprises from 0.01% to 5% by weight of a carboxylic acid and does not comprise a metal catalyst, and a gel that can be obtained by this method and the kit for implementing this method.
