Described herein is a 2K solvent borne coating system. The coating system includes an epoxy component (A), including: i) an epoxy resin; ii)—a solvent; iii)—at least one compound of formula (I):[(ER)(R′O)(HO)(R″)(SiO]  (I)and/or oligomer or polymer compounds of the compound of formula (I), and iv)—optionally, at least one non-catalytic additive; and an acid resin component (B), including: an carboxylic acid resin;

Scratch and mar resistant automotive coatings

A double coating, curing method, cured coating, and kit are provided. A first layer of the double coating can be a first cure coating composition, which has a first hydroxy-functional resin, a first crosslinking agent, and a non-polar catalyst. A second layer of a second cure coating composition can have a second hydroxy-functional resin, a second crosslinking agent, and a polar catalyst. The non-polar catalyst catalyzes crosslinking between the second hydroxy-functional resin and crosslinking agent, and not between the first hydroxy-functional resin and crosslinking agent. The polar catalyst catalyzes crosslinking between the first hydroxy-functional resin and crosslinking agent, and not between the second hydroxy-functional resin and crosslinking agent. The polarity of the catalysts can facilitate catalyst migration from one layer to the other. The separate compositions can be shelf-stable and/or the curing can occur at low temperature.
