Classification: CPC C | IPC B  C

Claim 0:
1. A 2K solvent borne coating system, comprising:
an epoxy component (A), comprising:
i) an epoxy resin, wherein the epoxy resin is an acrylic resin having an epoxy group in a side chain;
ii) a solvent;
iii) at least one compound of formula (I):

[(ER)x(R′O)y(HO)z(R″)t(SiO(4-x-y-z-t)]m  (I)

wherein
ER is an alkyl group substituted with an epoxide group or a cycloalkyl group substituted with an epoxide group,
R′ is an alkyl group of 1 to 6 carbon atoms,
R″ is an alkyl group of 1 to 20 carbon atoms which may be linear, branched or cyclic,
x is a number from 0 to 2,
y is a number from 0 to 4,
z is a number from 0 to 3,
t is a number from 0 to 2,
at least one of x and y is greater than 0, x+y+z+t=4, and m is =1 and/or oligomer or polymer compounds of the compound of formula (I), wherein partial hydrolysis and condensation provides structures containing epoxy side chains (ER), said structures containing up to 5000 monomeric units m; and
iv) optionally, at least one additive; and
an acid resin component (B), comprising:
a carboxylic acid resin including carboxylic acid groups;
a solvent;
optionally, at least one catalyst; and
optionally, at least one additive.
