Pros and Cons of Polyurea Adhesives

I understand that polyureas are very fast curing. Why don’t we see them used as adhesives?

October 29, 2020

Polyureas have a lot of similarity to polyurethanes, but they are two-component systems based on reacting an isocyanate with a multifunctional amine rather than with a polyol. This chemical reaction is extremely fast, quite often just a few seconds.

Isocyanates react with compounds that have active hydrogens. For example, in coating applications, isocyanates are typically reacted with polyols to form polyurethanes, or with primary and secondary amines to form polyureas. Catalysis of the polyol/isocyanate reaction, which is often required to develop sufficient cure response, can be achieved with a variety of compounds.

What types of chemical structures could be built into a polyurethane adhesive to optimize heat resistance? Can you make any formulation recommendations?

Ask Dr. Dave

Ask Dr. Dave: Should we consider silicones or polyurethanes for our construction applications?

Polyureas tend to be a little more expensive than polyurethanes, but their fast cure and outstanding properties often outweigh this.
