    PRODUCT CODE: ARH00
    TECHNICAL DATA SHEET NO. 06-Specialised Products
    JULY 2009

  1. Product Description

    NEO Heat Reflective Roof Paint is a water based, acrylic, durable roof coating with heat reflective abilities.
  2. Application Areas

    • Cement tiles, new or weathered.
    • Fibre cement sheeting, new or weathered.
    • Plaster.
    • Previously painted substrates.
    • Primed metal and wooden substrates.
  3. Product Features

    • NEO Heat Reflective Roof Paint, especially when white or in pastel shades, reduces the temperature in especially buildings with metal roofs considerably. It contains reflective minerals, which reflect infrared light rays from the surface of the coating. This results in a considerable reduction in the roof surface temperature and consequently the room temperatures.
    • Highly durable and UV resistant for the harsh Namibian climate.
    • Highly water resistant.
    • Excellent adhesion.
    • Low odour.
    • Quick drying - two coats can be applied in one day.
    • If correctly applied to a properly prepared substrate, the product has a life expectancy of 5 to 7 years, possibly longer. The use of the reflective minerals has a positive effect on the lifespan of the roof coating. Not only infrared but also harmful UV rays are reflected, thus slowing down the degradation of the coating.

    Resin Base Acrylic resin emulsion
    Drying Time Touch dry: ± 30 minutes
    Hard dry: ± 3-4 hours
    Solid Matter by Content By volume: 47%
    By mass: 62%
    Film Thickness 40-50 microns per coat
