corrosionpedia - what is an epoxy phenol novolac

Phenol formaldehyde resin

Phenol formaldehyde resins (PF) or phenolic resins are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde Used as the basis for Bakelite PFs were the first commercial synthetic resins (plastics) They have been widely used for the production of molded products including billiard balls laboratory

Novolak

Novolaks (sometimes: novolacs) are low molecular weight polymers derived from phenols and formaldehyde They are related to Bakelite which is more highly crosslinked The term comes from Swedish lack for lacquer and Latin novo for new since these materials were envisioned to replace natural lacquers such as copal resin Typically

Phenolic vs Epoxy Resin Work Surface

Epoxy resin will handle higher continuous heat loads including open flame and will maintain its looks and functional characteristics in severe laboratory conditions For lab environments that deal with sustained exposure to high heat or severely caustic chemicals epoxy may be the better choice but for most applications phenolic resin is your clear cut winner and new champion
