    JULY 2009

  1. Product Description

    A universal, solvent based, anti-corrosive metal primer. The product contains the proven anti-corrosive agent zinc chromate.
    A classic alkyd and zinc chromate based corrosion resistant primer for use on mild steel. Especially formulated to give good long term performance for the total system when used to provide a very strong and stable base for over-coating with a range of NEO Paints’ solvent based products.
  2. Application Areas

    • Interior and exterior use.
    • Mild steel substrates.
    • This primer is not suitable to prime galvanised metal.
  3. Product Features

    • Excellent corrosion protection.
    • Excellent adhesion and hiding power.
    • Can be top-coated with a wide range of NEO Paints’ decorative solvent based products.
    • NEO Zinc Chromate should not be used as a base for two-component or highly chemical resistant coatings. In such cases NEO Corroguard (cg00) or NEO Corrotec (ct00) is recommended.
    • A simple to use very effective metal primer, which prevents corrosion on steel through its anti-corrosive abilities and through protection. 
    • The coating dries to a hard, resistant coating which can be over-coated with undercoat and all types of enamel paints.
    • NEO Zinc Chromate contains a certain amount of zinc chromates. Although it poses no danger for the applicator, it can be harmful when removing the old paint coating by sandblasting or grinding. An alternative product based on non-toxic zinc phosphate, is NEO Corroguard (cg00).

  6. Surface Preparation

    • Mild Steel (Renovation) • Affected areas need to be cleaned back to bright metal and spot primed with NEO Zinc Chromate.
    • With brush or spray, apply a generous coat of NEO Zinc Chromate.
    • For very severe cases e.g. in very harsh marine environments, two coats of NEO Zinc Chromate are required.
    • Thereafter apply one coat of NEO Universal Undercoat (wu00) and two final enamel based coats.
    • Mild Steel (New) • Surfaces need to be abrasively degreased to remove the manufacturer’s grease protective layer. This process is repeated until the surface is water break free.
    • Remove any rust or mill scale from steel surface either by grinding, sanding or with use of a chemical de-ruster such as NEO Rust Remover (rr00).
    • For best results use sandblasting.
    • With brush or spray, apply a generous coat of NEO Zinc Chromate.
