Moisture-curing, hot-melt polyurethane adhesive compositions. |
摘要 |
A moisture-curing hot-melt polyurethane adhesive foam comprising isocyanate-terminated polyurethane prepolymers based on polyester or polyether and having a melting point of 40 DEG to 60 DEG C or a glass transition point above room temperature, melted together, optionally with a nucleating agent and/or a surfactant, treated with an inert gas under pressure and released in ambient pressure is allowed to cure as a foam whereby a cure rate is achieved of at least ten times that of the composition when not foamed. Extremely rapid cure rates are achieved and thick bond lines are readily obtained. |
