PN-1 Cyanate Waterproof Coating

Overview
Single-component cyanate waterproof coating for waterproofing and damp-proofing on building structures.​

Composition
Cyanate prepolymer, adhesion promoter, pigments, sealing additive, solvent, catalyst.​

Typical uses
Waterproofing and damp-proofing for cooling tower internal walls, sewage tanks, and basements.​
Can be used in systems with epoxy and polyurethane coatings.​
