ABSTRACT:
An anticorrosive primer composition comprises (1) 100 parts by weight of an epoxy resin having a number-average molecular weight of from 500 to 10,000, (2) from 10 to 60 parts by weight of an aromatic polyamine containing from 2% to 30% by weight, based on the aromatic polyamine, of a promoter selected from the group consisting of phenol compounds and cresol compounds, (3) from 10 to 60 parts by weight of a polyisocyanate, (4) from 10 to 40 phr, based on the sum of components (1), (2), and (3), of silica particles of colloidal silica or fumed silica or a mixture of these, (5) from 0.5 to 5 phr of a lubricant, and (6) an organic solvent. The composition is particularly suitable for use to apply onto the chromate coating of a chromated, zinc-plated steel sheet.
