ALKOXYLATED RESOL-TYPE PHENOL RESIN MANUFACTURING METHOD, ALKOXYLATED RESOL-TYPE PHENOL RESIN, RESIN COMPOSITION, AND COATING |
摘要 |
In order to provide a curing agent (alkoxylated resole-type phenolic resin) with which a coating film having high hot-water resistance, high workability, and high adhesion to metals may be formed without limiting the main agent to be a bisphenol-A-type epoxy resin, the present invention provides a method for producing an alkoxylated resole-type phenolic resin. The method includes reacting a phenol (a1) including meta-cresol with an aldehyde (a2) in the presence of a basic compound to prepare a resole-type phenolic resin (A); and reacting the resole-type phenolic resin (A) with an alcohol (B) in the presence of an acidic compound having an acid dissociation constant (pKa) of 0 or less. |
