SPE902 Vinyl Ester Resin Topcoat is a vinyl ester coating used as a topcoat. Suitable for the internal corrosion protection of flue gas desulphurisation low-temperature systems, and also as an anticorrosive topcoat for all concrete, including flues, tank interiors, drainage pits, channels and slurry ponds. A three-component product composed of bisphenol-A vinyl ester resin, fine glass flakes of 120–180 mesh, colouring pigments, a small amount of reactive diluent and additives; mix evenly per the metered ratio before application. Parameters on this page: dry film thickness 400 µm, theoretical spreading rate 2 m²/kg, number of components three.
