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: Efficiency in Seconds

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% while significantly reducing energy consumption.

Exceptional Adhesion: Mastering Diverse Substrates

With a 5B adhesion rating (ASTM D3359) on plastic films such as PET, PC, and PVC, the coating bonds tightly to substrates without primers, resolving traditional delamination issues.

Superior Flexibility: Dynamic Application Reliability

The modified molecular structure imparts rubber-like flexibility to the coating, enduring 100,000 bending cycles (ASTM D522) without cracking. Ideal for flexible display encapsulation.

Anti-Yellowing & Weather Resistance

Maintains color difference ΔE <1.5 after 1,000 hours of QUV accelerated aging. Withstands thermal cycling from -40°C to 120°C without delamination.
