Durex® Uraflex 360 NP is a Primerless, Elastomeric Traffic-Bearing Polyurethane Waterproofing Membrane. Durex® Uraflex 360 NP is a two-component, high solids, extremely elastomeric polyurethane waterproofing membrane that maintains flexibility in freezing temperatures. Durex® Uraflex 360 NP adheres to concrete and wood surfaces to form a highly effective waterproofing membrane. It must be top coated with a Durex® Traffic-Bearing Coating to achieve an effective Traffic-Bearing System.
- Outstanding water impermeability sealing properties
- Highly penetrable
- Very low VOCs
- Primer-free, tenacious substrate adhesion
- High chemical resistance to acids, alkalis, salts, seawater, sewage, and other compounds
- Fast-curing properties
- Excellent low-temperature flexibility and crack-bridging properties
- ASTM C957 (CAN/CSA-S413-07) Compliant
Durex® Uraflex 360 NP is a Primerless elastomeric, polyurethane-based waterproofing membrane that is used in conjunction with other Durex® Traffic-Bearing coatings to form a comprehensive, traffic-bearing, waterproofing system. It is designed to perform as a water-resistant traffic-bearing membrane on a variety of surfaces such as concrete and wood. Capable of bridging cracks up to 1/16 of an inch with excellent flexibility in cold temperatures.
