General description
HWR-638 is a semi-solid reaction product of epichlorohydrn 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.Property | Value |
