Title (EN) PROTECTED AIR-ACTIVATED ORGANOTIN CATALYSTS FOR POLYURETHANE SYNTHESIS
(FR) CATALYSEURS PROTEGES A BASE D'ORGANOTINE ACTIVES PAR L'AIR POUR LA SYNTHESE DE POLYURETHANNE
Abstract: front page image
(EN)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.
(FR)L'invention concerne un système de catalyseur protégé à base d'organotine pour la synthèse de polyuréthanne qui est utile dans des applications de revêtement. Le catalyseur présente une faible activité en l'absence d'oxygène. Lorsqu'un mélange de revêtement comprenant le catalyseur est pulvérisé et/ou appliqué à l'air comme film mince sur un substrat, le catalyseur est activé. Ce système de catalyseur confère une stabilité de viscosité, c.-à-d. une durée de conservation en pot prolongée aux systèmes de peinture automobile à base de solvant comprenant des espèces hydroxyle et isocyanate et à fortes teneurs en matières solides.
