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.
The new process offers numerous economic benefits. According to Henkel, no bath heating is required and Bonderite NT coatings can be applied at room temperature, thus saving energy. Speed is also accelerated; the throughput time for parts being treated is only about 20 seconds. Moreover, Bonderite NT makes passivation unnecessary, thus eliminating an entire process step.
The new process is also offers significant environmental benefits. In addition to its low energy needs, Bonderite NT is also distinguished by its entire lack of organic ingredients. Neither phosphates nor toxic heavy metals have to be disposed of, which means that far less sludge is generated in production. Outlay on wastewater treatment, waste disposal and plant cleaning and maintenance is significantly reduced.
