Epoxidized Soybean Oil Acrylate 6720: A High-Efficiency UV Coating Solution for Paper and Wood

Epoxidized Soybean Oil Acrylate 6720: A High-Efficiency UV Coating Solution for Paper and Wood

In the UV coatings industry where efficiency and environmental performance are paramount, Epoxidized Soybean Oil Acrylate 6720 stands out with five core advantages: low viscosity, moderate reactivity, excellent yellowing resistance, soft cured film, and superior wetting on substrates and pigments/fillers. It is an ideal solution for surface finishing on substrates such as paper, wood, and PVC—offering both high quality and excellent process adaptability to enable cost-effective, value-added production.

Low Viscosity

With a viscosity below 500 cps, 6720 offers excellent flow and application flexibility. It is easily compatible with high-speed coating methods like roll and curtain coating, minimizing overspray and material waste while increasing production efficiency by over 20%.

Moderate Reactivity

Balanced photoreactivity enables controlled curing within 8-12 seconds, avoiding internal stress from overly rapid crosslinking. This ensures stable production throughput and is particularly well-suited for multi-layer coating systems that require precise layer stacking.

Excellent Yellowing Resistance

Derived from natural soybean oil and enhanced with anti-yellowing technology, 6720 maintains excellent clarity under long-term UV exposure with ΔE < 1.5. It preserves the brightness and visual appeal of paper and wood coatings, meeting the high color stability demands of book covers and premium furniture finishes.

Soft Cured Film

The cured film is flexible and resistant to cracking, passing bending tests (1 mm mandrel) without damage. This makes it ideal for deformable substrates such as paper and soft PVC, preventing brittle fractures due to substrate movement and extending the lifespan of end-use products.

Superior Wetting Performance

6720 offers excellent wetting on porous wood, fibrous paper, and pigments/fillers like titanium dioxide and calcium carbonate. Adhesion improves by 35%, significantly reducing defects like pinholes and color float. Its compatibility with high-solids formulations supports lower overall system costs.

Recommended Core Applications

UV Varnish for Paper: High gloss, anti-curl performance that enhances print durability and visual quality

Wood UV Primers: Fast penetration into wood grain with excellent sealing, reducing topcoat usage by up to 20%

PVC Decorative Coatings: Flexible and aging-resistant, ideal for complex curved surfaces, minimizing delamination risk

Eco-Friendly Packaging Coatings: Compatible with waterborne systems and compliant with food-contact safety standards

Defining Quality Through Flexibility, Driving Innovation Through Efficiency

Epoxidized Soybean Oil Acrylate 6720 leverages technology to balance performance and cost—transforming every coating layer into a powerful tool for adding product value.
