PermaRez® 345S

PermaRez® 345S Saturant is a polymeric topcoat to the PermaRez 345 Crack- Bridging Chemical Resistant Composite Lining System. It is used as a saturant and bond coat to incorporate fiberglass reinforcement into the system, giving the system tensile strength between the elastomeric membrane and the chemical resistant topcoats. PermaRez 345 Saturant also serves as a bond coat for other PolySpec chemical resistant coatings.
