Abstract
Compositions useful for forming high gloss, transparent, hard, flexible, weather- and dirt-resistant coatings on substrate surfaces are prepared using a) fluoropolymer, such as KYNAR® resins and KYNAR Aquatec® resins from Arkema Inc, b) fluoropolymer-miscible polymer and c) one or more ethylenically unsaturated compounds capable of being cured by free radical means, such as urethane acrylate oligomers and monomer reactive diluents from Sartomer USA, LLC. The compositions are capable of being cured by free radical polymerization induced by, for example, irradiation or heating.
