SPE904-P Heat-resistant Vinyl Ester Resin Primer belongs to heat-resistant coatings, vinyl ester system. Suitable for coating of metal substrates and also for areas in long-term contact with chemical media. Three-component; it is composed of heat-resistant phenolic vinyl ester resin as the base, combined with suitable reactive diluents, additives, etc.; before application, mix uniformly according to the specified ratio and then apply. The film has outstanding adhesion to metal and concrete surfaces, and excellent resistance to chemical media, temperature changes and fatigue. Parameters on this page: dry film thickness 100 µm, theoretical spreading rate 9.33 m²/kg, number of components three-component.
Parameter source: OSAKA original technical data sheet (TDS) "SPE904-P Heat-resistant Vinyl Ester Resin Primer (≤200 °C)"; values such as spreading rate are converted from TDS parameters and are for selection reference only.
