PM-1 organic inorganic hybrid heavy anticorrosive coating is a new type of material obtained by crosslinking of modified polymer resin and inorganic silicate solution. It has the advantages of strong chemical resistance and stability of silicate and good mechanical and mechanical properties of resin and forms a dense protective layer, which can resist strong acid, strong alkali, high salt and most chemical corrosion for a long time. It is environmentally friendly, non-toxic, flame retardant and does not require primer. Can be brushed/roller coated/sprayed on carbon steel, stainless steel, concrete and other substrates, the construction period is short, widely used in Marine engineering, energy engineering, large industrial enterprises, transportation industry and municipal facilities heavy anticorrosion applications.
