SPE902-P Vinyl Ester Resin Primer is a vinyl ester paint, used as a primer. Widely used in vehicles, ships, heavy industry, chemical industry, power and environmental protection and many other fields; also suitable for protecting concrete surfaces such as drainage pits, channels and slurry pools. It is a three-component product based on a specially modified vinyl ester resin combined with suitable reactive diluents and additives; before application, mix uniformly according to the specified ratio, then apply. The film has outstanding adhesion to metal and concrete surfaces, excellent chemical resistance, temperature-change resistance and fatigue resistance. Parameters on this page: dry film thickness 80–100 µm, theoretical spreading rate 8.90–11.61 m²/kg, number of components: three.

A three-component product based on a specially modified vinyl ester resin, combined with suitable reactive diluents and additives. Before application, mix uniformly according to the metering ratio and it is ready for use. The film has excellent adhesion to both metal and concrete surfaces, with high resistance to chemical media, temperature variation and fatigue.
Widely used in vehicles, ships, heavy industry, chemical industry, power and environmental protection and many other fields; also suitable for protecting concrete surfaces such as drainage pits, channels and slurry pools.
