Methyl ethyl ketone
D.E.N.* 438-EK85 epoxy novolac
resin is a solution of a semi-solid
reaction product of epichlorohydrin
and phenol-formaldehyde novolac in
methyl ethyl ketone.
D.E.N. 438 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. 438 has multiepoxy
functionality (±3.6). These additional
reactive sites produce tightly
cross-linked cured systems. D.E.N.
438-EK85 epoxy novolac resin solution
is used alone or in combination
with bisphenol-A based epoxy resins
in solution formulations where ease of
mixing and processing is required.
The thermal stability offered by epoxy
novolac resins is a widely accepted
asset in pre-preg manufacture for
electrical laminates where they
improve the resistance to hot solder
as well as elevated temperature service.
They are also used in coating
applications where an increased corrosion/
chemical resistance is desired.
