ABSTRACT:
Adhesive formulations are blends of aqueous polymer dispersions and a hydrophobic plasticizer. The blended dispersed polymers include at least one hard sulfonated polyester urethane, at least one soft non-sulfonated polyester urethane, and at least one polar non-polyurethane water-based polymer or copolymer. A high molecular weight elastomeric non-sulfonated polyurethane polymer and a crosslinker are optional further components in the blend. The formulations are useful as non-heat activating, one-component adhesives which generate excellent green strength, water and heat resistant bonds.
