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.

Two component coating compositions and coatings produced therefrom

This invention relates to composite materials for restorative dentistry. More particularly, it relates to new components for dental composites, which impart an attractive combination of good mechanical properties and low shrinkage.

Materials leading to improved dental composites and dental composites made therefrom

This invention relates to rapid curing coating compositions that are particularly useful for automotive OEM and refinish applications. The coating composition includes a binder component that contains a novel highly branched copolyester polyol, and a crosslinking component that contains conventional crosslinking agents, such as polyisocyanate and melamine. This invention is also directed to a process for producing coatings from the rapid curing coating compositions. These compositions are especially useful in providing for mar resistant and flexible coatings.

Two component coating compositions containing highly branched copolyester polyol

A composition that can be used as a component in auto clear coat and primer is disclosed. The composition comprises or is an alkoxylated amine having the formula of (A)[N(RH)]including an isomer or mixture of isomers thereof. Also disclosed is a process, which comprises contacting an amine with an epoxide under a condition sufficient to produce an alkoxylated amine. Further disclosed is a composition that can be used as coating composition and primer, which comprises an alkoxylated amine and an organic polyisocyanate.

The invention is directed to a two-pack high solids low VOC ambient curable coating composition, which includes cross linking and binder components. The crosslinking component includes a polyamine, a polyketimine, or a combination thereof. The polyamine is provided on an average with at least two amine functionalities per polymer chain and the polyketimine is provided on an average with at least two ketimine functionalities per polymer chain. A reactive diluent in the binder component includes a macromolecule substantially free from acrylate functionalities and having at least two acetoacetate functionalities per the macromolecule. If desired, the coating composition includes a binder polymer. The coating composition of the invention is particularly suited in automotive refinish coatings.

Coating compositions containing highly structured macromolecules

This invention concerns low viscosity aldimine and ketimine reactive diluents having multi-imine functionality, which are useful in automotive refinish coating compositions, including a process for making them and the coatings that contain them.

Transparent electroconductive coating compositions, methods to prepare such coating compositions, and substrates coated with these coating compositions. The coatings are based on polymeric resins containing finely dispersed electroconductive powders. The coatings can be characterized by the following: thermoformable while retaining transparency and electrical conductivity that is insensitive to humidity; low chloride extractability, stable to exposure to isopropanol or water/soap solutions.
