VESTAGON EP-SC 5050

powder coating cure catalyst

Coatings

Catalyst for 1 – Uretdione based polyurethane powder coatings; 2 – Matte hybrid powder coatings – VESTAGON EP-SC 5050 is a catalyst that can be used in combination with 1) blocking agent free polyisocyanate adducts and hydroxyl-functional resins for polyurethanes and 2) matting hardeners based on salts of polycarboxylic acid plus cyclic amidines to enhance cure and gloss stability over the baking range of hybrid powder coatings. The product itself contains a tetraalkylammonium carboxylate adsorbed onto amorphous silica. The free flowing catalyst is delivered in the form of a very fine powder.
