CURABLE COMPOSITIONS AND METHODS OF CATALYZING CHEMICAL REACTIONS

Methods of catalyzing chemical reactions are provided. A tertiary amine blocked with an acid, the acid having a vapor pressure greater than 1.0 mm Hg at 25°C, is added as a catalyst to reaction mixtures. Reaction mixtures contain uretdione or isocyanate functional materials, in various combinations...

Zusammenfassung:	Methods of catalyzing chemical reactions are provided. A tertiary amine blocked with an acid, the acid having a vapor pressure greater than 1.0 mm Hg at 25°C, is added as a catalyst to reaction mixtures. Reaction mixtures contain uretdione or isocyanate functional materials, in various combinations with hydroxyl, thiol, and/or amine functional materials. Curable compositions comprising these catalysts and reaction mixtures are also provided. L'invention concerne des procédés de catalyse de réactions chimiques. Une amine tertiaire qui est bloquée avec un acide, l'acide ayant une pression de vapeur supérieure à 1,0 mm Hg à 25 °C, est ajoutée en tant que catalyseur à des mélanges de réaction. Les mélanges de réaction contiennent des matériaux à fonctionnalité uretdione ou isocyanate dans des combinaisons variées avec des matériaux à fonctionnalité hydroxyle, thiol et/ou amine. L'invention concerne des compositions durcissables comprenant lesdits catalyseurs et des mélanges de réaction.
