摘要:
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.
摘要:
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(R1H)2]p 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.
