SPE903 Abrasion-resistant Penetration-resistant Vinyl Ester Resin Topcoat is a vinyl ester coating used as a topcoat. It is specifically designed as a topcoat for anti-corrosion coating of the inner walls of FGD system absorber towers, and is also suitable for some areas in contact with other corrosive chemical media; please consult our company regarding the types of applicable media. Three-component; it is composed of bisphenol A vinyl ester resin, fine glass flakes of 120–180 mesh, colouring pigments, a small amount of reactive thinner, additives, etc. During application, mix uniformly according to the specified ratio before application. Parameters on this page: dry film thickness 400 µm, theoretical spreading rate 2 m²/kg, number of components three.
