PLY-1/PLY-2 Vinyl Ester Glass Flake Mastic

Overview
Two-component vinyl ester glass flake mastic for lining service in severe corrosion environments and thermal cycling.​

Composition
Vinyl ester resin (high corrosion resistance, high temperature resistance, high toughness) with specially surface-treated flake materials, additives, and corrosion-resistant pigments/fillers; paste-like material.​

Typical uses
Linings for steel structures and concrete buildings in harsh flue gas environments (power plants, smelters, fertilizer plants).​
Protection of internal/external surfaces of equipment, pipelines, and tanks for liquid media up to medium corrosion severity.​
Composite use with FRP (e.g., high-speed metal impellers).​
Acid-making and desulfurization environments and equipment; marine splash zone and harsh three-phase alternating corrosion environments.​
