D.E.N. 439-EK85 epoxy novolac resin
solution is a semi-solid reaction product
of epichlorohydrin and phenolformaldehyde
novolac in methyl ethyl
ketone.
D.E.N. 439-EK85 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-
EK85 has multi-epoxy functionality
(±3.8). These additional reactive sites
produce tightly cross-linked cured systems.
D.E.N. 439-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 are
required. The thermal stability epoxy
novolac resins offer 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 ethyl 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.
