NEO CORROGUARD
    ANTI-CORROSIVE PRIMER
    PRODUCT CODE: CG00
    TECHNICAL DATA SHEET NO. 03-Primers & Undercoats
    JULY 2009

  1. Product Description

    New generation water based, non toxic, anti-corrosive metal primer for use on degreased galvanised steel and rust free, clean and dry mild steel. Suitabable as primer for a range of NEO Paints’ water and solvent based decorative products.
    Very effective heavy-duty anti-corrosive metal primer.
  2. Application Areas

    • Interior and exterior use.
    • Degreased and/or weathered galvanised steel.
    • Rust free, clean, dry mild steel.
    • Sandblasted steel degreased galvanised metal and aluminium.
    • Highly recommended for high-corrosive areas such as coastal regions as well as in industrial environments and mines.
    • Can be used as an adhesion promoter on galvanised metal and as primer for old corroded zinc roofs.
    • Highly suitable as additional coating for steel primed with NEO Corrotec (ct00).
  3. Product Features

    • An anti-corrosive primer suitable for use in the Namibian environment.
    • Suitable for use on degreased galvanised steel and rust free mild steel.
    • Excellent adhesion.
    • Can be over-coated with a range of NEO Paints’ decorative water and solvent based products.
    • Low odour.
    • Based on a water based resin and can be diluted with water. No thinner is required which makes the primer highly cost efficient.
    • NEO Corroguard contains no lead or lead derivates, which makes this product environment friendly.
    • Developed after extensive testing in our salt spray cabinet and by long-term exposure at Walvis Bay. After one thousand hours exposure in salt spray the test panels showed no failure or deterioration. Other solvent based primers used in comparison failed between 500 to 1 000 hours in salt spray. These tests showed that a water based primer in combination with zinc phosphate and other rust inhibitors can be equal or even superior to conventional solvent based metal primers.
    • NEO Corroguard dries to a completely water insoluble, tough and abrasive resistant coating. The dry film thickness should not be less than 30 microns per coat. For coastal use we recommend a two-coat application. In the interior of the country one coat is sufficient.
    • Can be over-coated with enamel paints and water based paints.
  4. Product Data

    Resin Base Acrylic emulsion
    Drying Time Touch dry: 30–60 minutes 
    Hard dry: 2 – 3 hours
    Solid Matter by Content By volume: 44%
    By mass: 57%
    Spreading Rate 5 – 9 square metres per litre at 30 – 35 microns.
    Although the spreading rate will vary with porosity and type of substrate, for uncoated new surfaces, work on 5-7 square metres per litre for the first coat and 7-9 square metres per litre for subsequent coats and when applied to sealed, previously painted substrates.
  5. Application Details

    • Mixing Always stir well before use with a flat paddle.
    Due to extended storage NEO Corroguard may have a slightly jelly-type consistency. Thorough stirring will lower the viscosity of the primer considerably and result in a ready to use paint.
    • Application Method Air or airless spray and brush. Roller application is not recommended.
    • Thinning NEO Corroguard is ready for use un-thinned; thinning with water will reduce its hiding power and impair anti-corrosion protection.
    • Cleaning Water.
    • Application • Stir well before use.
    • With a brush or spray, apply a generous coat of NEO Corroguard.
    • For very severe cases e.g. in very harsh marine environments, two coats of NEO Corroguard are required.
    • Allow to dry 2-4 hours before recoating with NEO Paints’ water or solvent based products.
    • NEO Corroguard is ready for use un-thinned; thinning with water will reduce its hiding power and impair anti-corrosion protection.
    • Clean up application equipment with clean tap water.
    • NEO Corroguard should never be mixed with other products.
    • NEO Corroguard should never be used under two pack solvent based products.
    • Do not apply before 09:00 and after 16:00 in the winter.
    • Although the spreading rate will vary with porosity and type of substrate, for uncoated new surfaces, work on 5-7 square metres per litre for the first coat and 7-9 square metres per litre for subsequent coats and when applied to sealed, previously painted substrates.
    • Do not apply exterior if it looks like rain will occur within 4-6 hours of application.
  6. Surface Preparation

    • Mild Steel (Renovation) • Affected areas need to be cleaned back to bright metal by hand mechanical or blast cleaning.
    • Apply one or two coats of NEO Corroguard by means of brush or spray application, but not by means of a paint roller.
    • Mild Steel (New) • Degrease surfaces with NEO Metal Conditioner (mc00) to remove the manufacturer’s grease protective layer. This process is repeated until the surface is water break free.
    • After drying, the whole substrate is coated with one or two coats of NEO Corroguard.
  7. Colour Range and Quantities

    • NEO Corroguard is available in Red oxide only.
    • Available in 1 litre and 5litres (20 litres can be supplied on special order).
  8. Precautions

    • NEO Corroguard is not flammable.
    • Contains no toxic ingredients and very low VOC levels (EU regulations).
  9. Disclaimer

    NEO Paints can not be held liable if the product fails due to improper surface preparation or application.
