Product Overview
Model 56031: High-Performance Polyester Acrylate for Advanced UV Printing & Coatings
Model 56031 is a next-generation polyester acrylate oligomer engineered to solve critical formulation challenges in the UV curing industry. Distinguished by its exceptionally low viscosity, this resin allows formulators to create high-solid, solvent-free systems without compromising flow properties, making it a top choice for eco-friendly UV gravure varnishes and flexographic inks.
Its high reactivity ensures rapid polymerization under UV-LED or mercury lamps, significantly boosting production line speeds while delivering a surface with superior hardness and scratch resistance. Unlike standard resins, 56031 offers outstanding substrate wetting, ensuring perfect adhesion on difficult materials like BOPP, PET, and aluminum foils. It is specifically optimized for snow effect inks, providing the precise rheology needed to create sharp, durable textured finishes popular in luxury packaging.
Whether you are developing high-gloss overprint varnishes or specialized decorative coatings, 56031 delivers a perfect balance of performance and cost-efficiency.
