PLH55-28 Non-Toxic Epoxy Coating

Overview
Two-component epoxy coating system (primer/topcoat) formulated for internal lining protection where low odor and non-benzene solvent formulation is required.​

Composition
Imported special epoxy resin, curing agent, medical-grade pigments, fillers, additives; supplied as two components for both primer and topcoat.​

Typical uses
Internal lining protection for tap-water pipelines, water storage tanks, drinking water tanks/compartments, fresh water tanks, dry cargo holds, and grain silos.​
Protection for steel or concrete equipment/facilities in medical, food, beer, and beverage industries.​
