SWD9526 single component thick film polyurea


SWD9526 single component thick film polyurea

short description:

SWD9526 is a single component aromatic thick film polyurea anticorrosion waterproof coating material. It cures to form a thick-film membrane that provides excellent adhesive strength with concrete and steel structure, easy to apply without need of special polyurea spray machine. Because of the unique chemical structure, it is an ideal material for waterproof anticorrosion protection with high chemical resistance and waterproofing. The high elasticity and high strength makes it most suitable for building walls waterproof, seal water of structure crack and expansion joint, anti-seepage and leak stopping of harbor docks and dams.

Application instructions

Environment temperature: -5 ~35℃

Relative humidity: 35-85%

Dew point: when apply on metal surface, the temperature must be 3℃ higher than dew point.

Application guidance

Recommended dft: 500-1000um (or based on the design requirements)

Recoat interval: 2-4h, if exceed 24h or have dusts on the surface, use sandpaper to blasting then apply it.

Recommended application method: use scraper to scratch.


It can be used in the temperature below 10℃. When apply in extreme low temperature, keep the coating barrel in the air conditioning room for 24 hrs.

SWD advises to mix the coating barrel uniform, seal the package well after use to avoid moisture absorption. Not to put the poured out material into the original barrel again.

Viscosity is fixed before shipped, thinner shall not be random added. Instruct the manufacturer in special situation to add thinner.
