Polyurea Adhesives (i)

Applicable Base Polymer Properties

Polyureas are similar to polyurethanes but they are based on reacting an isocyanate with a multifunctional amine rather than with a polyol. The polyurea chemical reaction occurs quickly without added catalysts and can provide good bonding and physical properties within a few minutes at room temperature (although fully optimized properties may require several hours). Polyureas tend to be more expensive than polyurethanes, but their fast cure rates are often worth the extra cost.
