A catalyzed fast cure polyurethane sealant composition. |
摘要 |
<p>A polyurethane sealant composition is made from a polyurethane prepolymer having blocked isocyanate groups. A 1,8-diaza bicyclo(5:4:0)undecene-7 (DBU) catalyst or a derivative thereof is utilized in association with an amine curing agent having at least two primary amine groups to achieve a relatively fast cure time. The catalyst is a true catalyst in that it merely aids in unblocking the isocyanate groups whereby the curing agent can react therewith.</p> |
