PPR F520 is an aminofunctional co-reactant for polyisocyanates useful for the formulation of high-solids, two-component polyurethane topcoats and solvent-free coatings. PPR F520 can be reacted with -NCO functional HDI trimmer resulting in a longer gelling time and excellent yellowing resistance.
NK Ester HD-N is a difunctional acrylic monomer which can be polymerized by free radicals. In particular, this product is designed for use in UV and Electron Beam curing applications mainly as a crosslinker. It can also be used in anaerobic adhesive applicaitons.
