SWD8009 two components sealing penetration  concrete special polyurea primer


SWD8009 two components sealing penetration concrete special polyurea primer

short description:

SWD8009 two component sealing penetration concrete special polyurea primer takes high performance polyurethane resin pre polymer and high polymer as main film material. It has high fluidity and strong penetration into the substrate, seal the pinholes of concrete and has high adhesive strength. The coating film is eco friendly, it can greatly increase the adhesive strength when apply on concrete or other surface.

Application note

The concrete surface must be completely dry, clean, compact, with no grease or stains, if there has some obvious cracks and breaking area, it should be fixed in advance. Make sure to clean up the surface with air grinding or vacuum method prior to apply SWD8009.

This product can be applied on the temperature under -10℃. When apply on the very low temperature, put the material drums in the air-conditioning room for more than24h.

SWD recommends to agitate the coating uniformly prior to application, use up the mixed materials within 1 hour. Don’t pour the rest liquid to the original bucket.

The viscosity of product is set up in the factory, thinner shall not be random added by the applicators. Call the manufacturer for instructions to add special thinner if the viscosity changed with the application environment and humidity.
