High Toughness Cationic Hybrid UV Resin

U-9210 resin is a cationic and free radical hybrid system UV resin, and its low viscosity curing speed is faster than U-9310. It also has the characteristics of low shrinkage and high adhesion of the cationic curing system. It has excellent outdoor weather resistance and is recommended for use on organic and inorganic materials surfaces that are difficult to adhere to, such as glass, ceramics, and metals. At the same time, it maintains high hardness and flexibility, and has excellent water and chemical resistance. Grafted acrylate improves curing and construction properties and is suitable for various processes. It can be fully cured under the energy of 400-600mj. After being mixed with sulfonium salt and iodonium salt cationic photoinitiators, it can be used in UV coatings, inks, special adhesives that require extremely low shrinkage and high refractive index, film printing, optical fiber coatings and other fields with good results.

U-9210 is used as the main resin in UV optical adhesives and electronic packaging adhesives. It can provide excellent bonding performance, high refractive index and good moisture and heat resistance. Suitable for bonding in solar and other outdoor applications, glue molding, surface coating, aging resistance, and no yellowing. In UV coating applications, U-9210 has low film thickness and high performance, and is suitable for optical fiber coating. As special coatings such as film processing and low viscosity solvent-free spraying. In the field of 3D printing, U-9210 is used as the main resin for SLA industrial-grade 3D printing. It has low shrinkage, high molding accuracy, no yellowing, and is suitable for 355nm laser light sources. 25-100um film thickness, rapid curing with low exposure, and molding modulus with ABS-like plastic characteristics.

U-9210 is used in electronic packaging glue process
