SPE904 Heat-Resistant Vinyl Ester Resin Topcoat is a heat-resistant coating, in the vinyl ester coating system. Suitable for parts with heat resistance requirements, such as original flues, bypass flues and flue gas reheaters. Three-component, composed of bisphenol epoxy vinyl ester resin, fine glass flakes of 120-180 mesh size, coloured pigments, a small amount of reactive diluent and additives; at application, mix uniformly in the specified ratio. Parameters on this page: dry film thickness 400 µm, theoretical spreading rate 1.78 m²/kg, number of components: three-component.
Parameter source: OSAKA original technical data sheet (TDS) for SPE904 Heat-Resistant Vinyl Ester Resin Topcoat (≤ 200 °C); spreading rate and other values are converted from TDS parameters and provided for product selection reference only.
