Abstract: Compositions comprising a reaction product of a) an asymmetrical, saturated polyisocyanate that is non-cyclic, non-aromatic, and has at least 3 carbon atoms in the polyisocyanate per isocyanate group, b) a material that is at least one of i) a primary carbamate material having at least one functional group reactive with an isocyanate and at least one primary carbamate group or a group convertible to a primary carbamate group and ii) a reaction product of the primary carbamate material and an extending agent, and c) optionally, a chain extension agent that has at least difunctional reactivity with an isocyanate. Also, methods of making these compositions.

Abstract: A composition comprising a reaction product of a diisocyanate, a chain extension agent having at least difunctional reactivity with an isocyanate, and a material comprising a blend of i) a primary carbamate material having at least one functional group reactive with an isocyanate and at least one primary carbamate group or a group convertible to a primary carbamate group, and ii) a reaction product of the primary carbamate material with an extending agent, wherein at least one of i) the isocyanate groups of the diisocyanate have a different reactivity in relation to each other, and ii) at least two of the groups with reactivity with an isocyanate on the chain extension agent have a different reactivity in relation to each other.

Abstract: The invention provides coating compositions comprising a reactive component (a) which is substantially free of any heteratoms and is a not a crystalline solid at room temperature and which comprises from (i) 12 to 72 carbon atoms, and (ii) at least two functional groups, and (b) a crosslinking agent comprising a plurality of functional groups (iii) reactive with the functional groups (ii) of compound (a), wherein functional groups (ii) and (iii) are selected such that reaction there between produces a thermally irreversible chemical linkage. The coating compositions of the invention provide improved solids, chip resistance, flexibility and/or scratch & mar resistance while maintaining desirable and/or improved performance characteristics with regard to environmental etch, relative humidity, QCT, chip resistance, thermoshock resistance, cold crack resistance, adhesion and the like.
