Description

High-quality multifunctional 2-component acrylic primer with anti-corrosion additives. Thanks to the use of advanced technology and high-class ingredients, the product has a very wide range of applications. It works perfectly both as a filling undercoat and an insulating primer. It can be applied directly to metal, providing excellent anticorrosion protection for areas sanded to bare steel. It insulates difficult substrates and body fillers very well from varnish coatings, protecting them against the so-called mapping effect. An additional advantage of the primer is the possibility of applying it “wet on wet”, no sanding required.

Mixing the 3 colors of primer available in the right proportions allows you to obtain 2 additional colors, making it possible to work in the full spectrum of the grey system and select the recommended color of primer for the target base coat color.

Advantages

  • Excellent anti-corrosion protection of steel
  • Strong adhesion to various types of surfaces
  • Very good insulating and filling properties
  • Very short curing time
  • Can be applied using the “wet on wet” technique
  • Working in the spectral gray system.

Substrates

Mutifunctional acrylic primer DTM PRIMER SEALER can be applied directly on:

  • Steel and aluminum after matting and degreasing.
  • Zinc-coated steel and galvanized steel after matting and degreasing.

  • Polyester body fillers and putties.
  • Epoxy primers.
  • Wash primers.
  • Old paint coatings in good condition after matting and degreasing.

Good surface preparation is essential to achieve the best repair results.
