Henkel Bonderite M-ZN 958 (was Granodine 958)

Henkel’s Bonderite M-ZN 958 is a tricationic phosphating process that creates a dense phosphate coating inherently resistant to alkali attack. Suitable for use on most metal substrates, including electro- and hot-dip galvanised steel, zinc alloy coated steel (Zi/Ni), and aluminium, it produces a fine-grained surface with excellent morphology.

As a dip or spray pre-treatment, Bonderite M-ZN 958 is used before the deposition of cathodic electrocoats of all types. It is also highly effective as a pre-treatment to organic coatings.

The Bonderite M-ZN 958 process takes just two to three minutes, in a bath at 48-54C temperature. The process typically begins with Bonderite C-AK type alkaline cleaner, water rinse, and Bonderite M-AC 50 activating rinse. The Bonderite M-ZN 958 phosphating treatment is applied, followed by two water rinses, a Bonderite M-PT rinse, and finally a rinse in demineralised water.

The resulting phosphated surface is exceptionally dense and fine-grained, with intrinsic protection against alkaline attack especially when compared to conventional zinc phosphate surface treatments.
