Light Cure UV Resin

Many coatings attract oil and ink stains. Marker pens leave marks that are hard to clean. Winsir Light Cure UV Resin incorporates silicone chains into the acrylate. The cured surface has very low surface energy below 25 mN/m. Both water and oil have trouble sticking. We tested this with an elevator panel factory in Guangdong. Their button panels coated with our light cure UV resin cleaned fingerprints and oil stains with a simple wipe. This product meets ASTM D-3359 standards. It is used in anti-graffiti coatings, anti-fingerprint coatings for electronics, and kitchen/bathroom protection.

Winsir Light Cure UV Resin uses reactive silicone intermediates for block copolymerization with urethane acrylate or epoxy acrylate. Silicone content can be adjusted from 10% to 30%. The appearance is a clear to slightly hazy liquid. At 25°C, viscosity is 500 to 2,000 centipoise. Functionality is 2 to 3. Solid content is 100%. We recommend using it with radical photoinitiators like 184 or TPO. Cure is achieved under 300 to 500 mJ/cm² mercury lamps or high-power LEDs. The cured film has a water contact angle of 105° to 115°.

Winsir Light Cure UV Resin delivers very low surface energy. Water contact angle is 110° or higher. Hexadecane contact angle is 60° or higher. Vegetable oil and marker ink form beads on the surface. They wipe off easily. For anti-graffiti performance, marker pens leave no residue after dry or wet wiping. It passes EN 13523-22 anti-graffiti testing. For durability after abrasion, Taber abrasion testing per ASTM D-4060 shows water contact angle drops by less than 10° after abrasion. Washability is good. For adhesion and transparency, cross-cut adhesion on glass, metal, and PET film is level 0 to 1. Light transmittance is above 90% and does not affect the underlying pattern.
