    摘要: The present invention provides for an etch and mar resistant low VOC clear coating composition most suitable for use as a top clear coat in multi-layered OEM or refinish automotive coatings. The coating composition includes polyisocyanate, polyester polyol and melamine components, where more than half of total composition solids include the polyester polyol and melamine components. The polyisocyanate component includes an aliphatic polyisocyanate. The composition may be formulated as a two-pack or one-pack coating composition, wherein the isocyanate functionalities are blocked with a blocker such as a mono-alcohol.

    摘要: The present invention is directed to low VOC curable coating compositions suitable for use in various mar and etch resistant coatings, such as in automotive coatings. The binder of the composition includes silicon/hydroxyl and cross-linking components. The silicon/hydroxyl component includes one or more reactive oligomers having linear or branched cycloaliphatic moiety and at least two functional groups with at least one being a silane or silicate group, the remaining being a hydroxyl group. Applicants have unexpectedly discovered that by including silane or silicate functionalities in these reactive oligomers, the solids level of the composition can be significantly increased at reduced composition viscosities. As a result, such high solids low VOC compositions can be readily applied by conventional application means, such as by spraying.
