Description

Uraflex 361 Elastomeric Polyurethane Traffic Bearing Topcoat is a two-component, solvent-free, high solids elastomeric polyurethane topcoat specially formulated for traffic bearing surfaces. It is designed to adhere to Uraflex 360 Elastomeric Polyurethane Waterproofing Membrane and other similar membranes to form a highly effective traffic bearing waterproofing system.

Advantages
  • Resilient coating with high abrasion resistance.
  • Outstanding water impermeability sealing properties.
  • Very low odour and zero VOCs.
  • Potential LEED credits.
  • Excellent water immersion properties.
  • Self-cleaning, fast curing, and easy to apply and to maintain.
  • Superior abrasion and scratch resistance; high tensile strength.
Uses

Uraflex 361 Elastomeric Polyurethane Traffic Bearing Topcoat is used as a resilient topcoat for traffic bearing waterproofing systems. It can be recoated for additional wear resistance. Anti-slip performance is achieved by broadcasting silica sand or aluminum oxide grit into the coating. Uraflex 361 is ideal for: Parking Decks, Balcony terraces and pedestrian walkways, Mechanical rooms, Plaza, pool and recreational decks, and vehicular ramps, Stadiums, as well as Non-potable water retention tanks, cooling towers and secondary containment
