Chemetall introduces medium-temperature sealing technology for anodized aluminium

Chemetall, a leading global surface treatment supplier and a global business unit of BASF’s Coatings division, has launched a new generation of ecologically sound, medium-temperature sealing product for anodized aluminium surfaces.

Gardo® Seal 1999 allows the process to run at lower temperatures and shorter treatment times without compromising the appearance and quality of the surface finish.

Significant energy savings

“Manufacturers can achieve substantial energy savings while realizing higher production rates,” says Martin Ings, Chemetall’s Global Segment Manager for Aluminium Finishing, and adds: “The Gardo® Seal 1999 process enables customers to realize significant process cost savings.” Another benefit is the extended service time of the Gardo® Seal 1999 process baths, which significantly reduces the amount of water required for new bath make-ups.

REACH-compliant and Qualanod-approved

Chemetall’s new sealing technology is a robust process with a broad processing window. Surfaces sealed with Gardo® Seal 1999 are free of sealing blooms and meet all relevant quality standards such as DIN EN ISO 3210. The process is REACH-compliant and approved by Qualanod, the quality label for Sulphuric Acid-Based Anodizing of Aluminium.

Aluminium substrates sealed with Gardo® Seal 1999 ensure lightfastness and corrosion resistance of anodized and colored surfaces and thus, preserve their high-quality appearance for many years.

Besides the anodizing of aluminium for architectural applications, Gardo® Seal 1999 is also suitable for interior and exterior parts of vehicles, electric consumer goods such as mobile phones and tablets, lighting systems as well as machinery and construction equipment in the mechanical engineering industry.

Gardo® Seal 1999 promotes greater efficiency and a cost reduction while meeting today’s targets for an ecologically sound sealing process.
