Reaktive polyacrylate für den oberflächenschutz

Acrylic polymers find increasing application as binders for protective coatings. The monomeric acrylic compounds easily copolymerize with each other and with many other monomers, thus permitting the synthesis of polymeric substances with very different properties. By introduction of suitable functional groups into the copolymers the synthesis of reactive polymers is possible. These products are well soluble and easily processable and can be crosslinked by the application of heat to give products of excellent chemical and mechanical resistance. The reactive groups may be introduced either by use of reactive monomers or by reaction with a suitable prepolymer. Especially acrylic polymers with hydroxyl-, amide-, N-methylolamide-, epoxy-, and active CH-groups in the molecule have received considerable attention for protective coatings. The most important types of these polymers and their crosslinking reactions are discussed with special consideration of polymers with methylolamide functions. Finally examples of important fields of application for reactive acrylic coatings are given.
