More Information
Summary:A curable coating composition is provided having multi-functionalized acrylic copolymer and silicone imine resin curing agents. The acrylic copolymer of the curable coating composition has, in polymerized form, epoxy functionalized groups and cure compatibility groups and the silicone imine forms an amino-functional silicone in the presence of water. The coating compositions are useful in the field of superior weatherable and durable coatings and are useful to replace isocyanate-containing polyurethane based coatings. Also provided are coated articles produced from the curable composition. Se proporciona una composición de recubrimiento curable que tiene un copolímero acrílico multifuncionalizado y agentes de curado de resina de imina de silicona. El copolímero acrílico de la composición de recubrimiento curable tiene, en forma polimerizada, grupos funcionalizados con epoxi y grupos de compatibilidad de curado y la imina de silicona forma una silicona con funcionalidad amino en presencia de agua. Las composiciones de recubrimiento son útiles en el campo de recubrimientos duraderos y resistentes a la intemperie superiores y son útiles para reemplazar recubrimientos basados en poliuretano que contienen isocianato. También se proporcionan artículos recubiertos producidos a partir de la composición curable.
