WorléeAdd 487
Special polyester resin for improving the adhesion of solvent based 2K PU and stoving enamels to Metal substrates and melamine-coated chipboard, improves elasticity, flow-enhancing, NMP-free
WorléeAdd 487 is a reactive adhesion-promoting additive developed for air-drying, stoving, and two-component polyurethane (2K PUR) systems, meaning it is a chemical additive that enhances the adhesion of coatings to surfaces.
It significantly improves adhesion, particularly on metal substrates, and is thermally stable up to approximately 180 °C.
A notable feature of this product is that it is free from N-methyl-2-pyrrolidone (NMP). This is important, as NMP is often regulated or restricted due to health concerns.
