Moisture-Cure Urethanes

Moisture-Cure Urethanes

How do Moisture-Cure Urethanes Work? Moisture-cure urethanes are single-part structural polyurethane reactive adhesives that require moisture to cure. They are known as “reactive” adhesives because they need a catalyst, in this case exposure to moisture, to begin the chemical reaction of curing. Dispensing equipment needs to be completely sealed so that no moisture can get …
