Product Description
HJ-707Pis a two-component epoxy polyamide anticorrosive high performance primer containing
zinc chrome as rust inhibitive pigment. It cures to a tough and highly rust preventive coat.
Features and Benefits
· Easy to apply and can be applied via airless spray, conventional spray, brush or roller.
· Ideal for use as a field primer on interior and exterior steel as part of a system to be topcoated with
chlorinated rubber, epoxy and polyurethane topcoats.
· A rust inhibitive primer over iron and steel and protects steel from atmospheric corrosion.
· Provides much higher degree of protection than conventional primers in severe corrosive
· Excellent resistance to acids, alkalis, water, salts, oils, petroleum solvents.
· Has very low water and water vapour permeability.
· Has excellent adhesion, toughness, abrasion resistance and overall chemical and solvent
· While inferior surface preparation can never be recommended, HJ-707Pcan tolerate,
though with shorter life, power tool and hand cleaned steel surfaces.
· Ideal for high humidity, moisture, marine atmospheres, heavy rains, high temperatures, damp
conditions, very low dusty and fungus prone conditions.
· Durable and economical.
Recommended uses

Blasted Steel structures

Off-shore structures

Pipelines Power Plants

Fertilizer Plants Marine & Shore Installations

Surface Preparation
Steel - The surface should be blast cleaned to SSPC-SP 10-63T . loose rust and scales,
dirt, grease, oil, paint, wax, weak oxide films and other contaminants should be removed. Blast cleaning to
SSPC-SP 5-63 is recommended where heavy corrosive conditions exist or coating is
required to be immersed. That means a surface with a grey metallic colour, slightly roughened to form a
suitable anchor pattern for coatings. This surface is free of all oil, grease, dirt, mill scale, rust, corrosion
products, oxides, paint and other foreign matter. In absence of blast cleaning, prepare the metal surface by
wire brushing, sanding, grinding, scrapping or chipping with hand or power tools. Remove all the
contaminants. Apply one coat of HJ-707P. It can be overcoated with Durapoxy 0 Epoxy
Enamel, Anuthane Enamel Polyurethane or Monocoat Enamel Polyurethane, HJ-070
Chlorinated Rubber Enamel.
Non-ferrous Metals- Remove dirt, dust, oil, old paint etc. Degrease the surface with degreasing solvents
like xylene or tri-chloroethylene. Apply one coat of HJ-292 Wash Primer for obtaining maximum
adhesion. Apply one or two coats of HJ-707P.

· Brushes and spray equipments should be cleaned with Our Epoxy Thinner.
· The contents should be stirred thoroughly prior to use.
· After mixing Base and Hardener in recommended proportions, allow for 30 minutes induction
period or sweat-in-time (maturing) before application.
· When overcoating the weathered HJ-707P, ensure that the coating is free from all
contamination like oil, dust, grease, grease stains.
· This coating should always be thinned with Honest joy Epoxy Thinner. The use of alternative
thinners can severely inhibit the curing mechanism of the coating.
