Abstract: The present disclosure relates to an aqueous dispersion of a carboxyl-functional, unsaturated polyester containing a perfluoropolyether block prepared by the following steps: a) subjecting a carboxyl-terminated perfluoropolyether C to a reaction with an ethylenically unsaturated epoxy-functional compound D in the presence of compound E, wherein compound E is a carboxylic acid or anhydride with functionality of at least 2, to obtain carboxyl-functional, unsaturated polyester F, and b) neutralizing carboxyl-functional, unsaturated polyester F with a neutralizer G and dispersing it in water. The dispersion can be used to prepare a waterborne, UV-curable coating composition and used for easy-clean coatings for various substrates.

Abstract: The embodiments herein relate to a composition of a fluorinated polyurethane acrylate resin and a polyurethane acrylate resin, which, upon curing, is durable and has anti-stain and anti-scratch properties. The preparation of the composition is conducted with a one-pot multicomponent synthesis process, wherein multiple components are put together to carry out reactions simultaneously. The process is especially suitable for industrial scale production, and open for adding additive components to further adjust the performance of the prepared composition. The embodiments herein also relate to oligomers prepared in the synthesis process, as well as the use of the composition or oligomer to form a coating onto a substrate.

Abstract: The invention relates to a hydroxyl-functional polyester containing a perfluoropolyether block prepared by a method comprising the following steps: a) subjecting a carboxyl-terminated perfluoropolyether C to a reaction with an epoxy-functional compound D, and b) subjecting the reaction product of step a) to a reaction with a lactone E. The polyester thus prepared can be used in a coating composition, comprising further (b) an OH-functional or epoxy-functional resin, and (c) a hardener comprising groups reactive to the OH or epoxy-functional groups of resin (b).
