BONDERITE® offers a comprehensive range of chromium-free conversion coatings on the basis of zirconium, titanium or cobalt for the treatment of non-ferrous alloys. They offer excellent corrosion resistance and paint adhesion due to increased process stability.
BONDERITE® Nanoceramic coating products offer new pretreatment solutions to replace zinc and iron phosphating. The thin-film conversion coating (nanoceramic layer) ensures outstanding properties regarding paint adhesion and corrosion protection and simultaneously reduces the environmental impact. Suitable for the conversion treatment of multi-metal (steel, zinc, aluminum) and can be applied through dipping or spraying.
Non-crystalline, non-metallic iron phosphate coating that chemically adheres to metal surfaces. For improved paint adhesion and corrosion protection before painting.
In this process, the metal surface is coated with a polycrystalline structure of iron, manganese, nickel and zinc phosphates. BONDERITE® Zinc phosphating ensures excellent corrosion protection and prime adhesion of subsequent coatings. BONDERITE® Phosphate conversion coating is suitable for a variety of metallic surfaces including steel, galvanized steel, electrolytically galvanized steel, zinc alloy coated steel, aluminum, zinc, cadmium, silver and tin.
We offer a wide range of temporary BONDERITE® Corrosion protection products for almost all metallic products – with protection periods between a few hours and six months. Product types include water-based or oil/water emulsions, oil-based protective oils, protective oils with a dewatering agent, dewatering agents with a protective oil, dewatering agents and solvent-based cleaners.
Inhibitors reduce acid attack and embrittlement of the substrate caused by hydrogen absorption. BONDERITE® inhibitors are also available as individual product additives and can be added to base pickling liquids like sulfuric acid, hydrochloric acid and phosphoric acid. There are also inhibitors for high-temperature applications, galvanized surfaces, for the cleaning of industrial plants and for power boilers and pipelines.
Pickling products are usually acidic but can also be neutral. Acid pickling liquids are suitable for circulation, spraying or dipping processes and a variety of substrates, such as steel, iron, copper or aluminum.
In addition to cleaning, neutral cleaners offer temporary corrosion protection and are used for intermediate and final cleaning, cleaning after assembly and temporary corrosion protection.
Acid cleaners remove inorganic contaminants like oxides and limescale deposits. Pickling is used to prepare a substrate before applying a conversion coating.
Strongly alkaline cleaners are used in spray, immersion and ultrasonic baths and are recommended especially at the beginning of the BONDERITE® processes. A typical area of application is car body and parts cleaning. Alkaline cleaners remove organic contaminants like oils, grease, dust or pigments.
Developed for the bonding of components where a long service life must be observed before the joining process and the adhesive must be hardend quickly after joining.
They are pre-vulcanization inhibitors. In order to avoid premature vulcanization during processing, retarders are often added to the curing system. These compounds increase the induction time by reacting with the active accelerator fragment, which slows down or temporarily prevents the formation of zinc salt.
