Butaflow BT-71

Butaflow BT-71 is a tin-based catalyst comprised of dibutyltin dilaurate adsorbed onto a silica carrier. This product may be used in both e-caprolactam blocked polyurethane powder coatings and the internally blocked uretdione systems. Butaflow BT-71 is incorporated as a raw material during the premix stage of processing, and a laboratory investigation is recommended to optimize the concentration and processing conditions for a particular formulation. Typical dosage ranges from 0.1 – 1% based on total formula weight.
