Abstract
The curable urethane polymer adhesive or coating of the present invention comprises at least one ethylenically unsaturated monomer and in one embodiment an aliphatic conjugated diene monomer, a hydroxy functional monomer, and a colloid having hydroxy functionality and a moiety having isocyanate functionality. The colloid having hydroxy functionality is present with the ethylenically unsaturated monomer and the hydroxy-functional monomer during polymerization so as to become incorporated into the latex to provide stabilization.
Claims21
A curable urethane polymer adhesive or coating consisting essentially of:
- a latex comprising at least one ethylenically unsaturated monomer and an aliphatic conjugated diene monomer, a hydroxyl functional monomer, and a colloid with hydroxyl functionality selected from the group consisting of polyvinyl alcohols, glycols and hydroxethyl cellulose, present with the ethylenically unsaturated monomer and hydroxyl functional monomer during polymerization so as to become incorporated into the latex;
- and
- a moiety having isocyanate functionality.
A curable urethane polymer adhesive or coating consisting essentially of:
- a latex comprising 1 to 99 percent by weight of at least one ethylenically unsaturated monomer and an aliphatic conjugated diene monomer, 0.5 to 15 percent by weight of a hydroxy functional monomer, and 0.1 to 10 percent by weight of a colloid with hydroxy functionality selected from the group consisting of polyvinyl alcohols, glycols and hydroxyethyl cellulose, present with the ethylenically unsaturated monomer and hydroxy functional monomer during polymerization so as to become incorporated into the latex;
- and
- 0.5 to 15 percent by weight of a moiety having isocyanate functionality.
