• ARC S4+ Severe Chemical-Resistant Coating

An advanced reinforced thin film coating to protect structures against extreme chemical attack.

This is a 100% solids, VOC free application with enhanced mechanical properties and spark testable per NACE SP0188. It ensures high adhesive strength and resists concentrated chemicals.

ARC S4+ Severe Chemical-Resistant Coating is designed to:

  • Protect against extreme chemical attack in immersion
  • Provide extended wear resistance
  • Safely and easily apply by brush, roller, airless, or plural component spraying

Application Areas:

  • ​​Exhaust gas ductwork
  • Fans & housings
  • Chemical s​torage tanks
  • Chimneys & stacks
  • Heat exchangers​​
  • Tank linings
