摘要:
A resin coating composition comprising an epoxy resin derivative having an imidazoline ring functional group of the formula ##STR1## wherein R.sub.1 represents an alkylene group having 2 to 6 carbon atoms, each of R.sub.2, R.sub.3, R.sub.4 and R.sub.5 represents a hydrogen atom or a methyl group, and R.sub.6 represents a residue of a carboxylic acid,as a resin binder. This resin coating composition is useful for cationic electrodeposition coating.
摘要:
A vinyl or acrylic polymer-modified epoxy resin comprising a reaction product of(A) an epoxy group-containing vinyl or acrylic polymer,(B) a bisphenol compound, and(C) a diglycidyl ether of a bisphenol compound.
摘要:
An acid-neutralizable cationic electrodepositable resin composition comprising as a film-forming ingredient the reaction product of(A) an epoxy resin or an adduct of an epoxy resin with a primary amine and/or a secondary amine,(B) an amino-terminated condensation product between a maleinized fatty acid and a polyamine, and(C) a partially blocked polyisocyanate compound.The composition can form a cathodically electrodepositable aqueous bath by being neutralized with an acid, and can give a coated film having superior surface smoothness and corrosion resistance with a high throwing power.
摘要:
A process for preparing a cationic electrophoretic coating composition comprising the steps of:(I) mixing or reacting(1) a reaction product of an epoxy-amine adduct (A) and a partially blocked polyisocyanate (C) and(2) a reaction product of a polyamide (B) and a partially blocked polyisocyanate (C) and(II) dissolving or dispersing the resulting mixture or reaction product in an aqueous medium by neutralization with an acid.
