  • Thermosetting resinous binder compositions, their preparation, and use as coating materials
    Patent number: 4405763
    Abstract: A thermosetting binder composition for coating, comprising:(I) (1) A non-acidic resinous saturated compound having a molecular weight of at least 900, and an alcoholic hydroxyl content of at least 0.2 eq./100 g;(2) A non-acidic polyester of a polycarboxylic acid cross-linking agent having more than one .beta.-hydroxyl ester group per molecule, and at least one of components (1) and (2) having an alcoholic hydroxyl functionality of more than 2, and(II) A transesterification-promoting metal salt or complex curing catalyst which is soluble in liquid hydrocarbons.For aqueous compositions, component (I) (1) is preferably a neutralized epoxy resin/amine adduct and component (II) should be insoluble in water; they can be used for cathodic electrodeposition.

  • Esters containing phenolic groups as epoxy resin curing agents
    Patent number: 4214068
    Abstract: Phenolic curing agents, especially suitable for use in powder coatings, are prepared by reacting a dihydric phenol (diphenylol propane), a diepoxide (liquid diglycidyl ether of diphenylol propane), and a dicarboxylic acid (adipic acid) with the phenolic functionality in excess over the difference between the epoxy functionality and the acid functionality.
