The BONDERITE M-NT Process (former TECTALIS)

Metal Pre-Treatment - New Technology

The BONDERITE Metal Pre-Treatment New Technology Process (BONDERITE M-NT) is the fast, easy, green and efficient alternative to zinc phosphate: It is an innovative multi-metal pre-treatment which leads to superior corrosion resistance and paint adhesion on the level of zinc phosphating.

BONDERITE Metal Pre-Treatment New Technology is suitable for dip and spray applications.

Technical Details
A Nano Process with thin Coatings

BONDERITE M-NT forms a cohesive, inorganic, high-density coating.This protective layer is significantly thinner than zinc phosphate coating and has been specifically developed for all metal surfaces, like steel, zinc and aluminum.

BONDERITE M-NT coatings are generally less than 100 nm in thickness. Being a typical representative of the nanoceramics, it combines ecological saving potentials with superior quality and performance.

Robust Process

The operation window of BONDERITE M-NT is in general broader while still delivering superior quality.

Major Cost Savings with BONDERITE M-NT

BONDERITE M-NT stands for major cost savings in comparison to traditional zinc phosphating lines.

Why is BONDERITE M-NT “green”?

BONDERITE M-NT coatings are composed of nanoceramics. Thus, the BONDERITE M-NT conversion coating is free of nickel, phosphate, VOC and CO2 equivalent emissions resulting in minimal environmental impact. Sludge formation is marginal, leading to significant savings in maintenance and disposal.

BONDERITE M-NT is applied at ambient  temperature, reducing utilities and natural resource requirements. Thus, the pretreatment footprint can be reduced significantly in a brownfield site as well as in a greenfield operation:
