ABSTRACT:
Melamine-formaldehyde based adhesive compositions having enhanced bond strengths when subjected to thermal and mechanical stresses. The invention further describes a process wherein melamine-formaldehyde resins are reacted with amines in the presence of water-based sulfonated polyurethane-urea polymers. The process substantially reduces the release of formaldehyde and generates a network of interpenetrating polymers having enhanced peel adhesion failure temperatures.
