Features & Benefits
- Ready-to-Use Product Features
- Product Features
- Colorless, transparent, with excellent gloss.
- Suitable for a wide range of pH exposure (pH 0- 10).
- Excellent resistance to hydrochloric acid, sulfuric acid, and salt water.
- Epoxy functionality provides compatibility with many topcoat formulations.
- Two variants: One has enhanced abrasion resistance (2x lower ΔHaze) and one has enhanced corrosion resistance (20+% better) relative to each other.
- Product Highlights
- Abrasion: Excellent resistance to abrasion and mechanical damage. Taber abrasion superior to stainless steel, electroless-Ni, Type III anodization.
- Adhesion: Excellent on correctly degreased and corrosion free surfaces.
- Chemical Resistance: The fully cured coating offers excellent resistance to aqueous solutions and industrial chemicals.
- Temperature resistance: Dry service temperature range up to 150°C.
