Abstract
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.
