Introduction

Exposed urethane, DU-245 and DU-2000(one-liquid type), are highquality urethane resins with excellent elasticity and tension. Due to their
excellent elasticity and tension, they are not cracked if the concrete is cracked. Therefore they are used as waterproof coating materials.

Uses

  •  Rooftop waterproofing for apartment buildings and other buildings
