7913 is a highly reactive 9-functional Polyurethane Acrylate (PUA) resin designed specifically for high-performance UV-curable coatings. It provides high cure speeds, high gloss, and excellent mechanical resistance properties.
Thanks to its high reactivity and 9-functional structure, 7913 cures exceptionally fast under UV light. This high-speed curing rate optimizes automated processing lines, shortens cycle times, and reduces energy consumption.
7913 resin is widely used in high-end wood flooring and furniture varnishes due to its excellent abrasion, scratch, and steel wool resistance. If formulated with appropriate UV absorbers, it can also deliver excellent long-term durability on various exterior substrates.
Acrylic monomers and oligomers require dissolved oxygen to prevent premature polymerization. Leaving at least 15% headspace filled with air ensures the stability of the UV-curable resin and prevents unwanted gelation during storage.
The product must be stored in a cool, dark, and well-ventilated dry space below 35°C. Exposure to direct sunlight, high heat sources, or UV sources must be strictly avoided to prevent accidental polymerization.
