Product Description
Product Description
7224-1 is a high-performance aliphatic polyurethane acrylate (PUA) photocuring resin, meticulously designed to meet the demands of premium UV applications. It combines multiple advantages including low shrinkage, excellent flexibility, fast curing, superior film formation, outstanding yellowing resistance, and low exotherm during curing, making it an ideal choice for various UV formulations.
During photocuring, the 7224-1 resin exhibits extremely low volume shrinkage, effectively reducing internal stress caused by shrinkage. This significantly enhances the flexibility of the coating or adhesive layer and its adhesion to substrates. This makes it particularly outstanding in applications requiring good bending performance and impact resistance, such as flexible UV leather, UV plastics, and UV nail gels.
This resin features a rapid curing speed, which can greatly improve production efficiency and shorten processing times. Simultaneously, its low heat generation during curing is especially suitable for heat-sensitive substrates like thin wood veneers, certain plastics, and nails, preventing substrate deformation or damage due to overheating.
After curing, the 7224-1 resin forms a smooth, high-gloss film with excellent physical properties. As an aliphatic polyurethane acrylate, it possesses outstanding UV resistance, ensuring long-term non-yellowing and maintaining the aesthetic appeal of the product. This is particularly important for light-colored or transparent UV nail gels, UV wood coatings, and UV plastic finishes.
Thanks to its balanced performance, the 7224-1 resin is widely used in various UV systems, including UV nail gel, UV leather, UV wood coatings, UV plastics, and UV inks, making it an ideal choice for enhancing UV product performance.
