D.E.N.* 438-A85 epoxy novolac resin
is a solution of a semi-solid reaction
product of epichlorohydrin and phenol-
formaldehyde novolac in acetone.
D.E.N. 438-A85 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-A85
has multi-epoxy functionality
(± 3.6). These additional reactive sites
produce tightly cross-linked cured systems.
D.E.N. 438-A85 epoxy novolac
resin 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 acetone. Used for high temperature applications such as coil, marine and protective coatings. Produces tightly cross-linked 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.
