ABSTRACT:
A red lead primer paint having excellent wetting and penetrating characteristics, which when applied to the surface of ferrous metals forms a tough, resilient, adherent coating characterized by having excellent weathering and corrosion inhibiting properties, is comprised of a red lead pigment well dispersed in a binder of raw linseed oil and long oil alkyd resin. The red lead primer paint has a pigment volume concentration (PVC) within the range of about 25% to about 30%. The concentration of the red lead pigment in the primer paint is in the range of 0.25 to 2.2 pounds per gallon (29.95 to 263.56 grams per liter) of solids. The binder is comprised of raw linseed oil and a long oil alkyd resin mixed in a ratio within the range of 1:1 to 2:1.
