Product Description
Characteristics One component primer is easy to apply. It has high permeability that deep into the substrate’s porous surface, fix micro defects and be firmly bonded together with substrate. The coating film is dense and tough, with excellent proof effect, anticorrosion, temperature variation resistance and waterproof, it will not peel off after long-term immersion in water. It has high bonding strength and greatly increase the adhesive strength with substrate and following layers.
