Description

Uraflex 375 UV Non-Yellowing Elastomeric Polyurethane Traffic Bearing Topcoat is a liquid applied, two-component, 100% solids elastomeric polyurethane topcoat. It is specifically formulated to adhere to Uraflex 360 Elastomeric Polyurethane Waterproofing Membrane and Uraflex 361 Elastomeric Polyurethane Traffic Bearing Topcoat to form a highly effective, UV stable, abrasion resistant, elastomeric traffic bearing waterproofing system.

Advantages
  • 100% solids, zero VOC.
  • Potential LEED credits, high recycled content.
  • Excellent UV Resistance, featuring non-yellow aliphatic urethane resin technology.
  • High abrasion resistance, resilient elastomeric coating.
  • Outstanding water impermeability & sealing properties.
  • Excellent water immersion properties.
  • Self-cleaning, fast curing; easy to apply and maintain
Uses

Uraflex 375 UV Non-Yellowing Elastomeric Polyurethane Traffic Bearing Topcoat is engineered to provide a tough, durable, resilient topcoat for outdoor traffic bearing surfaces subjected to UV exposure. It can be re-coated for additional wear resistance and used with aggregates for non-slip performance. Uraflex 375 UV is ideal for: Exposed parking decks and vehicular ramps, Plaza decks, pool and outdoor recreational decks, Open Stadiums and sporting arenas, Exposed Balcony terraces, pedestrian bridges and walkways, Petrochemical refineries, as well as Areas exposed to UV rays.
