摘要： Disclosed are latent two-part polyurethane adhesives that rapidly develop adhesive strength when cured by application of infrared radiation containing a polyol component which includes; one or more polyols having a hydroxyl equivalent weight of 400 to 2000 and a nominal hydroxyl functionality of 2 to 3; one or more aliphatic diol chain extenders; one or more latent room temperature organometallic catalysts; and one or more multifunctional polyols having a functionality of greater than 3; b) a polyisocyanate component containing one or more polyisocyanate compounds; and v) a carboxylic acid-blocked cyclic amidine compound, vi) a phenol-blocked cyclic amidine compound or both of v) one or more carboxylic acid-blocked cyclic amidine compounds and vi) one or more phenol-blocked cyclic amidine compounds which may be located in the polyol component or the isocyanate component. Further disclosed are methods of bonding structures together using the latent two-part polyurethane adhesives.

摘要： Two-component polyurethane adhesives include a polyol component and a polyisocyanate component. The polyol component includes a polyether polyol and an aliphatic diol chain extender, but is devoid of primary and second amine compounds. The polyisocyanate component includes one or more polyisocyanate compounds. The adhesive contains a mixture of a dialkyltinthioglycolate catalyst and an acid-blocked cyclic amidine catalyst. The tin catalyst is formulated into the polyol component, whereas the cyclic amidine catalyst can be formulated into either the polyol or the polyisocyanate components.
