Abstract: Polymeric compositions containing spiroorthocarbonate groups and another functional group which reacts with hydroxyl groups are readily crosslinked on contact with water. These compositions are useful as sealants, coatings and encapsulants.

Abstract: The present invention is directed to two component coating compositions that cure under ambient conditions and more particularly to those having low VOC (volatile organic content) that are suitable for use in automotive refinish and Original Equipment Manufacturing (OEM) applications. The coating composition includes crosslinkable and crosslinking components, wherein the crosslinkable component includes a low polydispersity, low molecular weight copolymer having on an average 2 to 25 functional groups, such as hydroxyl, carboxyl, acetoacetoxy, primary and secondary amine, and epoxy. The copolymer is polymerized from a monomer mixture that includes one or more non-functional acrylate monomers and one or more functional methacrylate monomers provided with the functional groups. The crosslinking component includes polyisocyanate, polyamine, ketimine, melamine, epoxy, polyacid or a combination thereof. The invention is also directed to coating produced from the coating composition.

Abstract: This invention provides for a two-pack solvent based coating composition that cures in two stages when applied over substrates. The first stage of the cure takes place rapidly under ambient conditions to produce a coating surface that can be readily sanded or buffed. Thereafter, over a period of days a second stage cure takes place to produce a coating having excellent coating properties. Thus, a coated component, such as automotive body, can be speedily moved out from a spray booth without affecting the surface quality of the coated surface. As a result, coating operation productivity can be increased. The aforedescribed dual cure properties of the coating composition result from including in a binder component of the coating composition an acrylic polymer having secondary amine and hydroxyl functionalities. The composition is most suited for use in automotive refinish applications.

Abstract: The invention is directed to a two-pack solvent-based ambient curable coating composition comprising a binder of a hydroxyl and crosslinking components. The hydroxyl component includes a linear or branched cycloaliphatic moiety-containing reactive oligomer or blend of oligomers with a weight average molecular weight not exceeding 3,000, a polydispersity not exceeding about 1.7 with at least 2 hydroxyl groups, at least 1, on average, being a primary hydroxyl group. The reactive oligomer is formed by the reaction of an oligomeric acid with monofunctional epoxy. The crosslinking component includes one or more of an oligomeric crosslinker containing at least 2 isocyanate groups. The coating composition of the invention is particularly suited in automotive refinish coatings.
