EBECRYL® 4766 can be combined with isocyanate functional urethane acrylate resins for the formulation of coatings cured by a dual-cureprocess (UV induced polymerization and NCO/OH reaction).; Suitable (1)isocyanate functional urethane acrylate resins include EBECRYL® 4141 ,(1)4510 (1) and 4765 .Coatings formulated with EBECRYL® 4766 are applied by spraying, curtain coating or roller coating (≤100g/m2) and cured after an adequate flash-offtime, if required.Dual-cure processes include: NCO/OH reaction followed by UV curing. The NCO/OH reaction canprovide a non-blocking coating suitable for thermo or vacuum forming processes.; UV curing of the formed coating increases its durability and chemical resistance.; UV curing to provide a hard coating surface, with subsequent NCO/OH reaction which provides through curing, particularly inpigmented systems and shadowed areas.; The reaction of the isocyanate groups can be accelerated with standard two-component polyurethane catalysts. Photo-initiators are required forUV curing, with typical photo-initiators being suitable.; The type and amount of catalysts and/or photo-initiators should be adjusted to the plant and process condition.; Pot-life of two component-systems should be tested in accordance with the planned application.
