D.E.N. 438-MAK80 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-MAK80 has multi-epoxy functionality (± 3.6). These additional reactive sites produce tightly cross-linked cured systems. D.E.N.438-MAK80 is used alone or in combination with bisphenol A based epoxy resins insolution formulations where ease of mixing and processing is required. D.E.N. 438-MAK80 is used in coating applications where an increased corrosion/chemical resistance is desired.
Solution of D.E.N. 438 in methyl n-amyl ketone mainly for laminating or prepreg applications.
