In the field of UV-curable materials, Aliphatic Polyurethane Acrylate 7291B stands out with its exceptional performance, making it the ideal core ingredient for high-end applications such as adhesives, relief resins, and extension gels.
7291B features an innovative formulation that significantly enhances resistance to UV aging. It maintains the original clarity of the material over time, effectively solving the common issue of yellowing in conventional UV resins that compromises end-product aesthetics. This makes it especially suitable for crafts, decorative building materials, and other applications demanding high color stability.
Whether bonding to metal, plastic, or glass substrates, 7291B achieves efficient penetration and strong anchoring. Its molecular design ensures outstanding adhesion strength, greatly improving the peel strength and durability of UV adhesives. It offers reliable support in scenarios such as precision electronic encapsulation and automotive component assembly.
While maintaining high hardness, 7291B incorporates flexible segments to deliver excellent impact resistance, preventing brittleness and making it ideal for detailed carving in relief resins. Its unique surface film formation results in a smooth, non-tacky touch after curing, greatly enhancing application efficiency and reducing material waste.
As a functional raw material with excellent compatibility with most UV monomers and resins, 7291B is injecting fresh innovation into the UV industry chain, enabling customers to develop differentiated products that combine performance with premium quality.
