Abstract: A formula comprising MC-102 acrylic emulsion 25%, aluminium dihydrogen phosphate15%, boric acid 0. 01%, zinc acetate dihydrate 0. 01%o and diethylene glycol monobutyl ether 2% was used to prepare coatings via different treatment process. The conductivity test and polarization curves revealed that a coating cured at 300 ℃ for 60 s showed good insulative and anticorrosive properties. The water boiling test indicated that the said coating had good water resistance. A cross section of the coating was investigated by scanning electron microscope(SEM), indicating that the coating had good adhesion.

Key words: phosphate, hybrid coating, performance test
