Elvacite™ 4026 is a methacrylate resin that was designed to be used to improve the performance of UV & EB curable formulations. Elvacite™ 4026 utilizes a unique UV reactive macromolecular design that allows faster cure rate, reduced shrinkage, lower viscosity, improved chemical resistance, increased flexibility, and improved adhesion. Many times a cost savings can be achieved by using Elvacite™ 4026 in place of expensive, acrylate functionalized oligomers. Elvacite™ 4026 is soluble in many common acrylic monomers including TPGDA, HDDA, and TEGDA. When formulating with this resin it is recommended to dissolve it in monomer before adding to the other components. it should be used in combination with acrylate functionalized oligomers at a ration of 30/70 to 50/50.
