PLJ52-4 Chlorosulfonated polyethylene gas holder dedicated coating (primer/intermediate/topcoat)

Overview
Single-component chlorosulfonated polyethylene gas holder dedicated coating for external wall protection.​
Provides resistance to water, hydrogen sulfide, and chemical gas corrosion; fast drying and suitable for low-temperature application.​

Composition
Formulated with chlorosulfonated polyethylene resin, modified resin, quality pigments, mixed solvents, and multiple additives.​

Typical uses
Protection of gas holder outer walls; also suitable for anti-corrosion of other steel structures.​
