Claim:
A moisture-curable resin consisting essentially of: an aliphatic isocyanate functional material consisting of an allophanate reaction product of hexamethylene diisocyanate and a hydroxy-functional polyether, with the proviso that the ailihatic funtional material does not include isocyanurate or iminooxadiazine; a cycloaliphatic isocyanate functional material consisting of an allophanate-modified isocyanurate trimer reaction product of isophorone diisocyanate and a mono-functional alcohol; and optionally additional components selected from the group consisting of additive resins, pigments, tint pastes, pigment wetting agents, pigment dispersants, light stabilizers, UV-absorbers, rheology modifiers, defoamers, dehydrators, solvents, catalysts, wherein a coating composition comprising the resin exhibits no substantial sag when applied at a wet film thickness of at least 6mils and wherein the coating composition exhibits no substantial blistering when cured to a dry film thickness of at least 6 mils.
