Application Areas
Application Method
Buffing：Use a tungsten carbide buffing disc to roughen the damaged rubber surface of the conveyor belt. Avoid polishing the surface or causing rubber scorching during buffing.
Cleaning & Drying：Thoroughly wipe the surface and residual debris with a neutral detergent until all contaminants are removed. Let the surface air-dry naturally or dry it with heating.
Primer Application：Apply an even single coat of rubber primer onto the pre-treated rubber surface. It takes around 15 minutes to dry at an ambient temperature of 25℃.
Mixing：Blend Component A and Component B at a weight ratio of 20:1. Stir rapidly and fully within 1 minute. Prepare the adhesive on demand and consume it entirely within the working time.
Coating：Apply the mixed adhesive to the treated rubber surface with a short-bristle brush or glue squeegee, and control the coating thickness within 2 mm.
Precautions
1.Flammable material. Store in sealed container under dry conditions.
2.Ensure adequate ventilation at the construction site.
3.Avoid contact with skin and eyes before curing. In case of accidental splashing into eyes, immediately flush thoroughly with plenty of clean water and seek medical attention.
4.Ensure adequate ventilation at the construction site.
