Valve outside the protection
Name Spray Polyurea Protection Material
Model HTSPUA-4002
Description The coating system consists of amine-terminated resin, arylamine chain extender and MDI prepolymer. The product is dual-component, self-cured and thick coating anti-corrosion material.
Applications Applied to outer-wall waterproof protection of thermal insulation materials such as polyurethane foam, EPS foam, mineral cotton fiber and pearlite, and thermal insulation layer protection of light thermal insulation roof, large thermal insulation storage tanks and thermal insulation pipelines. It solves the problems that the outer protective iron skin of storage tanks used in coastal cities is easy to corrode and peel off in case of typhoon and the patch of the pipe system easily causes leakage.
