Description

Uretel MC One-Component Moisture Curing Polyurethane Membrane is a single component, high solids, moisture curing elastomeric polyurethane waterproofing membrane formulated for use in traffic-bearing and waterproofing applications. It adheres to concrete and wood surfaces to form a highly effective waterproofing membrane. Uretel MC must be top coated with a Durex® Traffic-Bearing Coating to achieve an effective Traffic-Bearing System.

Advantages
  • Outstanding water impermeability sealing properties
  • Highly penetrable
  • One Component, moisture curing polyurethane
  • Highly elastomeric
  • Excellent water immersion properties
  • High chemical resistance to acids, alkalis, salts, seawater, sewage and other compounds
  • Fast-curing properties
  • Excellent low temperature flexibility and crack-bridging properties
Uses

Uretel MC is an elastomeric, single component 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 1.6mm (1/16 of an inch).
