Novolak compounds useful as adhesion promoters for epoxy resins |
摘要 |
A composition useful as a powder coating comprises an epoxy resin and a novolak compound or resin having a structure obtained from the reaction of a substituted phenol such as cresol and an aldehyde to form a substituted bis(hydroxymethyl) phenol intermediate which is then reacted with a polyhydroxyphenol containing adjacent hydroxyl groups such as catechol to yield a polyhydroxyphenol-endcapped novolak compound or resin.
