Sinepoxy ® PER-DF638
(Phenolic Epoxy Resin)
General information:
PER-DF638 is a semi-solid reaction product of epichlorohydrin 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.
