| description | The present invention describes a silicone epoxy resin, its preparation, and the use in corrosion-inhibiting, heat-stable coatings. The process for preparing silicone resins comprises reacting I) siloxanes of the general formula R a Si(OR')b O(4-a-b)/2 in which OR' is an alkoxy group with primary or secondary aliphatic alcohols having from 1 to 8 carbon atoms, R is identical or different and is an alkyl group having from 1 to 8 carbon atoms or an aromatic group having from 6 to 20 carbon atoms, a is from 0.1 to 2.0, and b is from 0.1 to 1.0, with II) one or more low molecular mass polyhydric alcohols/polyols and III) one or more resins containing epoxide groups, containing at least two 1,2-epoxide groups per molecule, at temperatures in the range from 100 to 160.degree.C with removal of the alcohol HOR' to a degree of conversion of from 20 to 80% and terminating the reaction by cooling to a temperature < 100.degree.C. |
