hot/wet resistance, low coefficient of thermal expansion
SM-ER-65 Resin
Good mechanical properties, good hot/wet resistance, low coefficient of thermal expansion.
Product Description：
SM-ER-65 is a high-purity, low-viscosity liquid naphthalene-based epoxy resin. The rigid naphthalene ring delivers a superior combination of high glass transition temperature (Tg), extremely low moisture absorption, and a low coefficient of thermal expansion (CTE).
CAS NO. 27610-48-6
Classic Applications:
Hot/wet resistant aerospace composite prepregs.
High-performance Copper Clad Laminate (CCL) matrix or modifier.
