D.E.N.* 431 epoxy novolac resin is a
semi-solid reaction product of
epichlorohydrin and phenol-formaldehyde
novolac.
D.E.N. 431 epoxy novolac resin combines
in one molecule the thermal stability
of a phenolic backbone with the
reactivity and versatility of an epoxy.
D.E.N. 431 epoxy novolac resin has
multi-epoxy functionality (± 2.8).
These additional reactive sites, as
compared to a bisphenol-A type
epoxy resin, produce tightly crosslinked
cured systems. This makes
epoxy novolac resins especially useful
in adhesives, electrical and structural
laminates, coatings and castings for
elevated temperature service.
D.E.N. 431 epoxy novolac resin will
exhibit chemical resistance and
elevated temperature performance
between the properties of D.E.N. 438
epoxy novolac resin and the bisphenol-
A based liquid epoxy resins.
Adhesives based on D.E.N. 431 epoxy
novolac resins are ideal for use as
binders for abrasives in grinding and
polishing products. The low viscosity
of D.E.N. 431 epoxy novolac resin
makes it especially suited for electrical
varnishes, filament-wound pipes and
highly chemical resistant coatings for
storage tanks.
