Product Description

 
Product Description

Product Name: Epoxy Resin 638
Quality Standard: Tech grade
Description: Epoxy resin 638 is a semi-solid reaction product of epi chlorohydrin and phenol-formaldehyde novolac. It has advantageous characteristics of good adhesion strength, excellent heat and chemical resistance because of its multi-functional groups in one molecule fully cross-linked. Therefore, it has excellent physical properties in addition to the basic reactivity of general Epoxy Resin
