Abstract: A curable coating composition is described comprising a carbamate functional material, a crosslinking agent and a hydroxyl functional polysiloxane component. Coatings prepared with this coating composition can be cured and coated with additional coating(s), providing good intercoat adhesion to the subsequent coating.

Abstract: There is described a curable coating composition having at least one effect pigment which, upon cure, exhibits substantially improved orientation of the effect pigment and a corresponding improvement in appearance. The composition comprises:(A) a carbamate-functional component having a hydrophobicity equivalent to or greater than that of a carbamate-functional compound (A') which is the reaction product of:(1) a compound comprising a plurality of hydroxyl groups, at least one of which is the result of a ring-opening reaction between an epoxy group and an organic acid group, and(2) cyanic acid or a compound comprising a carbamate group, and(B) a component comprising a plurality of groups that are reactive with the carbamate functional groups on component (A), and(C) at least one effect pigment,the curable coating composition when cured having a substantially improved effect pigment orientation. Preferably, the composition further comprises particular rheology control agents.

Abstract: The present invention provides a curable coating composition comprising(a) a first component comprising at least two functional groups, at least one of which is a carbamate or urea group that is the reaction product of:(1) a hydroxyl group that is the result of a ring-opening reaction between an epoxy group and an organic acid group, and(2) cyanic acid or a carbamate or urea group;(b) a curing agent having a plurality of functional groups that are reactive with component (a), and(c) a second component having functional groups that are reactive with component (a) or component (b) or both components (a) and (b).

Abstract: A sterically-hindered monomer is used to make a polymer which in turn is useful in coating compositions. The resulting residue of the sterically-hindered monomer is present in the polymer, as well as in a cured coating (preferably an automotive coating) produced using a coating composition having the polymer therein. The presence of the residue of the sterically-hindered monomer imparts in the cured coating a resistance to environmental etching.

Abstract: Curable coating compositions are described comprising(a) a polymer resin comprising active hydrogen-containing functional groups,(b) a curing agent having groups that are reactive with said functional groups on (a), and(c) a compound comprising at least one carbamate group that is the reaction product of:(1) a hydroxyl group that is the result of a ring-opening reaction between an epoxy group and an organic acid group, and(2) cyanic acid or a compound comprising a carbamate group.
