Product Description

UV-Curable Modified Epoxy Acrylate 61003A: The "Versatile Innovator" in Industrial Coatings

At the forefront of UV-curing technology, modified epoxy acrylate has emerged as a premium material for demanding applications such as plastic film UV coatings, UV inks, and LED-UV potting, thanks to its rapid curing speed, excellent adhesion, superior flexibility, outstanding anti-yellowing properties, and exceptional weather resistance. It delivers dual value to industrial manufacturing by enhancing both efficiency and durability.

Rapid Curing Speed

Triggered by UV light, its molecular chains achieve crosslinking curing within 3-5 seconds, enabling compatibility with high-speed roll-to-roll coating lines. This boosts production efficiency by over 30%, making it ideal for smartphone protective film coatings and flexible packaging printing.

Exceptional Adhesion

With a 5B adhesion rating (ASTM D3359) on plastic films such as PET, PC, and PVC, the coating bonds tightly without primers, solving delamination in automotive interior films and electronic screen hardening.

Superior Flexibility

Imparts rubber-like flexibility, enduring 100,000 bending cycles (ASTM D522) without cracking. Ideal for flexible display encapsulation and wearable device UV inks.

Anti-Yellowing & Weatherability

Maintains color difference ΔE <1.5 after 1,000 hours QUV accelerated aging testing and withstands thermal cycling from -40°C to 120°C for outdoor signage and LED chip potting compounds.
