D.E.N.* 439 epoxy novolac resin is a
semi-solid reaction product of
epichlorohydrin and phenol-formaldehyde
novolac.
D.E.N. 439 epoxy novolac resin is a
general purpose, widely used epoxy
novolac resin. It is recognized as a
standard for high temperature applications
from which variations have been
developed. D.E.N. 439 has multi-epoxy
functionality (±3.8). These addi-tional
reactive sites produce tightly crosslinked
cured systems. D.E.N. 439
epoxy novolac resin is useful in adhesives,
structural laminates, coatings
and castings for elevated temperature
service. The thermal stability of a phenolic
backbone with the reactivity and
versatility of a bisphenol-A epoxy resin
are combined in D.E.N. 439 epoxy
novolac resin. Laminates can be made
using D.E.N. 439 resin in combination
with mica, synthetic glass-fiber or
fiberglass reinforcement.
