Multi DTM 4:1

Description

High-quality 2K multifunctional acrylic primer with the addition of anti-corrosive agents and a very wide range of applications. It works perfectly both as a filling and a grounding primer and can be applied directly to metal, providing excellent protection against corrosion for areas sanded to bare steel. An additional advantage of the primer is the possibility of applying it with the „wet on wet” technique, without the need for sanding.

Advantages

  • Excellent anti-corrosion protection of steel.
  • Very good insulating and filling properties.
  • Very short curing time.
  • Can be applied using the „wet on wet” technique.
  • Strong adhesion to various types of substrates.

Substrates

Acrylic primer MULTI DTM 4:1 can be applied over:

  • Bare steel and aluminum after matting and degreasing
  • Zinc coated, galvanized steel.
  • Polyester laminates (GFK/GRP).
  • Wash primers.
  • 2-pack polyester putties, polyester spraying fillers.
  • 2-pack acryl fillers.
  • 2-pack epoxy fillers.
  • Old finishes in good condition.
  • Good surface preparation is necessary to achieve the best results of repairs.
