J55-4 Chlorosulfonated polyethylene cooling tower dedicated anti-corrosion and damp-proof coating (primer/topcoat)

Overview
Single-component chlorosulfonated polyethylene cooling tower dedicated anti-corrosion and damp-proof coating system for inner wall protection.​
Provides resistance to chemical corrosion, freeze-thaw, damp heat, cold, and mildew; fast drying and suitable for low-temperature application.​

Composition
Formulated with chlorosulfonated polyethylene resin, modified resin, pigments, damp-proof agent, vulcanization accelerator, and organic solvents.​

Typical uses
Cooling tower inner wall protection.​

Technical data (typical)
