medium-high viscosity, thermal resistance
SM-ER-30 Resin
Medium-high viscosity, flexible structure, resistant to thermal aging
Product Description：
SM-ER-30 is a polyoxyethylene ether-modified bisphenol-A epoxy resin. It functions as an excellent internal flexibilizer, offering low viscosity, yellowing resistance, and seamless compatibility with standard BPA epoxies to dramatically improve toughness and impact resistance.
Classic Applications:
Toughening additive for structural adhesives and laminates.
Semiconductor and IC encapsulation materials.
Fiber-reinforced composites requiring high impact resistance.
