D.E.N.* 438-MK75 epoxy novolac
resin is a solution of a semi-solid
reaction product of epichlorohydrin
and phenol-formaldehyde novolac in
methyl isobutyl 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-MK75 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.
Coil Coatings
Marine & Protective Coatings
Standard semi-solid reaction product of epichlorohydrin and phenol-formaldehyde novolac in methyl isobutyl ketone. Used for high temperature applications such as coil, marine and protective coatings. Produces tightly crosslinked cured systems. Can be used alone or in combination with bisphenol-A based epoxy resins. Offers ease of mixing and processing, thermal stability and increased corrosion and chemical resistance.
