Henkel Product Supplier

Metal Pre-treatment

General overview

For pre-treatments before coating, Henkel Surface Technologies offers a full range of products that significantly improve the adhesion properties of organic coatings and that ensure extremely good protection against corrosion. The entire process can be described by the following process steps: cleaning, activating, phosphating and post rinsing/passivating.

Nano-ceramic technology (NT)

Bonderite NT is suitable for surface pretreatment for all conventional powder and wet paint coatings. It can be applied by dipping or spraying and creates a cohesive, inorganic, high-density layer incorporating nanoparticles. Measurements have shown that the nanoceramic coating delivers markedly better corrosion protection and paint adhesion than iron phosphating

Zinc phosphate

Zinc phosphate layers are generated on steel, zinc, aluminum and magnesium by means of acid phosphate solutions, sometimes containing fluoride additives, in spray or immersion applications. The formation of the zinc phosphate layer can be increased with the use of our accelerator products.

Iron phosphate

Henkel Surface Technologies offers a wide range of special products for the surface treatment of steel, cast iron, aluminum and galvanized substrates.

Passivation / Post Rinse

Chromium-free, as well as, chrome containing post rinse / passivation products are used to seal the phosphate coating.

Conversion Coatings

Prior to top coating, the metallic surfaces have to be pre-treated with an appropriate conversion layer. This provides the substrate with an anticorrosive layer that acts, at the same time, as an adhesion promoter for organic coatings. The specialized products from Henkel Surface Technologies ensure that the parts have a high quality and long lasting finish.

We supply a two-component process for the green chromating of aluminum; absolutely safe in food-manufacturing processes as well as Yellow chromating powder compounds that are particularly suitable for treatments as per MIL C 81706. Chromium-free process systems are also available.

Manganese phosphate coating for wear reduction

Products for the treatment of iron and steel, for various applications, with excellent friction and abrasion reducing properties i.e. in machinery and motor parts. Our manganese-iron phosphate layers improve lubrication and free running properties of components in machinery and motors.

Decorative Coatings

A black oxide coating can be applied to iron and steel components to provide a durable and attractive finish and is a simpler process than the traditional "blackening" originally used by gunsmiths.

Paint Strippers

A range of highly effective paint strippers allow re-work of products that have been painted or powder coated.
