Abstract

Abstract PURPOSE:To provide the titled compsn. which gives a coating film having excellent rustproofness and barrier to corrosive materials, by blending a scaly lead alloy pigment to a specified vehicle. CONSTITUTION:Stearic acid or mineral spirit is added to a lead alloy contg. 0.05-5wt% Cu, Ni or Sb. The mixture is processed in a ball mill to obtain a scaly lead alloy pigment (A) having a particle size of 10-100mu and a thickness of 0.5-3mu. 10-900pts.wt. component A and optionally an extender pigment, a suspending agent, a diluent, etc. are blended with 100pts.wt. at least one vehicle selected from among drying oil, alkyd resins, phenolic resins, chlorinated rubbers and vinyl resins to obtain a rust-inhibiting paint compsn. The compsn. is applied to a substrate to be coated in a coating thickness of 20-200mu and dried at room temp. or by heating.
