The number average molecular weight (Mn) of a standard phenol novolac resin is between 250 and 900. Rheological measurements indicated that cresol novolac/epoxy mixtures have an increased processing window compared to phenolic novolac/epoxy mixtures. Epoxy esters provide a hard, durable film ideal as a machinery finish. They are related to Bakelite, which is more highly crosslinked. Novolaks (sometimes: novolacs) are low molecular weight polymers derived from phenols and formaldehyde. Properties and Applications. PHENOLITE is a novolac phenol resin for epoxy resin curing agents.
