Coating compositions comprising cyclic carbonate amine resins

A cyclic carbonate-amine resin coating composition comprising:

• from 15% to 60% by weight of a cyclic carbonate acrylate polymer component having a polymer backbone comprising 15% to 45% by weight of a monomer unit comprising a cyclic carbonate functionality having the structure:
• where R3 is H, CH3, or CH2CH3;
• from 5% to 50% by weight of an amino functional silicone resin component having a general formula:
• wherein each R1 is a difunctional (C1-C4)alkyl radical and R2 includes greater than 70% phenyl groups, less than 0% of (C1-C4)alkyl groups, and less than 2.0% (C1-C4)alkoxy groups, and m has a value so that the amino functional silicone resin has an amine equivalent weight of 240 to 280 g/NH;
• from 0.0% to 5.0% by weight of a trialkoxy functional aminosilane having a general structure:
• where R4 is a difunctional (C1-C6)alkyl or a (C1-C6)alkylamino(C1-C6)alkyl organic radical group and each R5 is independently a (C1-C6)alkyl group;
• and
• from 0.0% to 5.0% by weight of a cure accelerator comprising a bicyclic guanidine catalyst,
• wherein the combined composition reacts to form a cross-linked cyclic carbonate-amine resin polymer.

A method for preparing a cyclic carbonate-amine resin coated surface comprising:

• reacting 15% to 60% by weight of the total coating composition, of a cyclic carbonate acrylate polymer component having a polymer backbone comprising 15% to 45% by weight of a monomer unit comprising a cyclic carbonate functionality with 5% to 50% by weight of the total coating composition of an amino functional silicone resin component having general formula:
• wherein each R1 is a difunctional (C1-C4)alkyl radical and R2 includes greater than 70% phenyl groups, less than 30% of (C1-C4)alkyl groups, and less than 2.0% (C1-C4)alkoxy groups, and m has a value so that the amino functional silicone resin has an amine equivalent weight of 240 to 280 OTT, to form an uncured cyclic carbonate-amine resin coating composition;
• applying the uncured cyclic carbonate-amine resin coating composition to at least a portion of a surface of a substrate;
• and
• curing the uncured cyclic carbonate-amine resin coating composition on the substrate surface to form a cross-linked cyclic carbonate-amine resin coat.

• a cyclic carbonate acrylate polymer component having a polymer backbone comprising from 15% to 45% by weight of a monomer unit comprising a cyclic carbonate functionality;
• and
• an amino functional silicone resin component having a general formula:
• wherein each R1 is independently a difunctional an aryl, an alkyl, a dialkylaryl, an alkoxyalkyl, an alkylaminoalkyl, or a cycloalkyl organic radical, each R2 is independently an aryl, phenyl, (C1-C4)alkyl, (C1-C4)alkoxy, or —OSi(R2)2R1NH2 group, and m has a value so that the amino functional silicone resin has an amine equivalent weight of 240 to 280 g/NH,
• wherein the combined composition reacts to form the cross-linked cyclic carbonate-amine resin polymer coating after applying the uncured coating composition to the surface.
