Full Description 

SC-3900 UB is a fast-set, high performance, spray-applied, plural component, 100% pure urea-based elastomer. This system is based on amine-terminated polyether resins, amine chain extenders, and prepolymers. It provides a cost effective flexible, tough, resilient monolithic membrane with water and chemical resistance.

SC-3900 UB is available with cutting-edge Ultra Bond™ technology. Advanced Ultra Bond™ chemistry is coined “the duct tape molecule”. Ultra Bond™ has the unique advantage of adhering to most properly prepared organic and inorganic (new and aged) surfaces without requiring a primer. Like duct tape, SC-3900 UB with Ultra Bond™ gains adhesion over time.

As with most coatings, there is a re-coat window that presents a lack of inter-coat adhesion. The UB™ molecule mitigates this risk during installation.
