Abstract:
Moisture-activated adhesive compositions are provided which comprise the reaction product of (a) a polyisocyanate and (b) an isocyanate-reactive component comprising an aliphatic tertiary amine-initiated polyol having an ethylene oxide content of at least 1%. Methods for bonding substrates with the present adhesive compositions are also disclosed.
The invention relates to compositions having an alkylene carbonate and a primary hydroxyl functional capping agent selected from the group consisting of methoxypolyoxyethylene monol, polyoxyethylene-polyoxypropylene monol, and mixtures thereof for treating materials fouled with isocyanate. The invention also relates to decontamination of materials fouled with isocyanate, and to methods for decontamination of solvent fouled with isocyanate.
The disclosed invention relates to polyisocyanate derived adducts and to emulsifiable polyisocyanates formed from those adducts. The invention further relates to emulsions which include the emulsifiable polyisocyanates. Emulsions which employ the emulsifiable polyisocyanates have greatly increased stability.
