Features & Benefits
- Ready-to-Use Product Features
- Product Features
- Colorless, transparent, with excellent gloss.
- Suitable for a wide range of pH (pH 0-10).
- Excellent resistance to hydrochloric acid, sulfuric acid, and salt water.
- Can be applied over ITO, SiO2 and other coatings.
- Product Highlights
- Abrasion: Excellent resistance to abrasion and mechanical damage. Taber abrasion superior to stainless steel, electroless-Ni, Type III anodization, and many commercially available hardcoats for polycarbonate.
- Adhesion: Excellent on degreased, corrosion-free, and activated glass, Al, and polycarbonate.
- Chemical Resistance: The fully cured coating offers excellent resistance to aqueous solutions and industrial chemicals.
