A GOOD BASIS: ZINC FLAKE BASECOATS

The basecoat series from Dörken MKS are the basis for a wide range of requirements and areas of use. And we have been continuously improving our basecoats for 30 years, adapting them to specific customer requirements and changing market situations.

BASECOAT – THE PRINCIPLE

The basecoat is the actual zinc flake coating, applied directly to the substrate. The application technology can vary, depending on component. The dip spin process is typical for bulk products. The basecoat determines the corrosion protection characteristics of the system, with the zinc responsible for the cathodic protection.

The right basecoat for every requirement

  • The original DELTA®-TONE 9000 product was developed specifically for springs, spring band clips and stamping parts.
  • A new product family developed in 2001 is ideally tailored to the requirements of threaded parts. Pilot product here was the DELTA-PROTEKT® KL 100, which fulfils long-term temperature loads of 96 hours at 180°C – requirements specified by many automobile manufacturers.
  • Since 2005 the portfolio has been augmented by DELTA-PROTEKT® KL 105: this uses integrated lubricants to remove the requirement for a topcoat, it is set to the specific coefficient of friction 0.12–0.18 µtot (as per ISO 16047) and therefore enables cost savings as a 2-in-1 system.
  • In the portfolio since 2013 is DELTA-PROTEKT® KL 130: the dark grey basecoat is ideally suited for black topcoats, as points of impact are not visible.
  • Finally, the current DELTA-PROTEKT® KL 120 sets new standards on the market. Its resistance to red and white corrosion goes far beyond the standard. It is particularly well-suited for threaded fasteners and springs/spring band clips. It is also currently first choice for large components, for example in combination with a scratch-resistant topcoat.

WE WILL GLADLY HELP YOU TO PICK THE APPROPRIATE BASECOAT FOR YOUR NEEDS.
