  This invention relates to a protected organotin-based catalyst system for polyurethane synthesis that is useful in coatings applications. The catalyst has low activity in the absence of oxygen. When a coating mixture comprising the catalyst is sprayed and/or applied to a substrate as a thin film in air, the catalyst is activated. For solvent-based refinish systems comprising hydroxyl and isocyanate species at high solids levels, the catalyst system therefore provides extended viscosity stability, i.e., pot life.

  这项发明涉及一种用于聚氨酯合成的受保护的有机锡基催化剂体系，适用于涂料应用。该催化剂在没有氧气的情况下活性较低。当包含该催化剂的涂料混合物在空气中喷涂和/或涂抹到基材上形成薄膜时，催化剂被激活。对于含有高固体含量的羟基和异氰酸酯成分的溶剂基涂装系统，该催化剂体系因此提供了延长的粘度稳定性，即潜伏期。
