Operation and Safety Guidelines
Surface Preparation:
Before applying the adhesive, clean the surface using gauze or appropriate tools to remove dust, loose particles, oil stains, and water marks. If rust is present, remove it with a wire brush, then clean the area using acetone or alcohol.
Primer and Cleaning Agent:
To ensure optimal adhesion, use the appropriate primers and cleaning agents. When applying these materials, make sure the coating is uniform, with no excess buildup or missed areas on the substrate surface.
Mixing:
PU7052, a two-component polyurethane structural adhesive, should be mixed using a static mixing tube.
Application:
Apply the PU7052 adhesive using a pneumatic or electric dispensing gun, or other suitable application equipment, directly at the construction site.
