One-component flexible etch resistant clearcoat

摘要: The present invention provides one-component compositions which comprise one or more hydroxyl functional acrylic resin having a glass transition temperature (Tg) of from −100° C. to −10° and dialkyl dicarboxylic acid ester endcapped polyisocyanate crosslinker, such as the isocyanurate isophorone diisocyanate (IPDI), flexible, environmental etch resistant coatings made therefrom. resins polymerized reaction product flexibility conferring monomers, e.g. butyl acrylate, provide coating with its flexibility. groups in react cure at lower temperatures than current blocked isocyanate coatings. Alternatively, consists essentially rigid aliphatic polyisocyanates. coated, exterior automotive plastic parts, bumpers, fascia, body trim molding.
