C-EP 4239EC Technical Data Sheet

PRODUCT DESCRIPTION 產(chǎn)品描述

C-EP 4239EC is a single component, heat curable, electrically conductive, modified epoxy adhesive. C-EP 4239EC是一款單組分改性環(huán)氧體系的熱固化導(dǎo)電膠。C-EP 4239EC具有以下優(yōu)勢：

Low stress 低應(yīng)力
High elasticity 高彈性
Good adhesion on nearly all surface 與絕大多數(shù)物質(zhì)表面有很好的粘結(jié)性。
Mismatched TCE application 熱膨脹系數(shù)失配的表面應(yīng)用
