EBECRYL® 4250 is an undiluted isocyanate functional urethane acrylate designed for use as adhesion promoter in UV and EB coatings. It may be combined with hydroxyl-bearing resins to formulate coatings which cure by dual-cure process (UV-induced polymerization and NCO/OH reaction). EBECRYL® 4250 is also used in pure UV-curing coatings to improve the adhesion on critical substrates as plastic, metal, and exotic woods. EBECRYL® 4250 is suitable for the formulation of moisture-curing one-component polyurethane coatings, especially for one-component adhesion primers.
