General industry (steel)

AD Chemicals develops, produces and supplies a complete product range of chemicals for the iron phosphating process. Next to traditional iron phosphating products AD offers a portfolio of innovative iron phosphate alternatives to create a perfect finish on steel substrates.

Iron phosphating for general industry (steel)

The AD phosphate technology has been developed with the high quality demands of iron and steel coating companies in mind.Iron phosphating (short phosphating) is a chemical pre-treatment process. During the process, a layer of insoluble phosphates is applied to the metal surface. This layer is often referred to as the “conversion layer”. Phosphating is used to provide steel and iron with corrosion protection, in addition, the phosphate layer improves paint adhesion. In order to achieve additional corrosion protection and paint adhesion a passivation product can be added to the final treatment bath.

Steel (phosphate) portfolio

• Degreasers
• Degrease and phosphate combination products
• Pickling/Etch products
• Iron Phosphating chemicals (PHOSPHATE 06H)
• Passivation additives, chromium-6 free (PreCoat ADL-4P)

Iron phosphate alternatives

AD Chemicals is known for its innovative power with associated continuous product development and has developed a range of alternative products for the phosphating of iron based on polymer/silane and trivalent chrome technology. This makes it easy to switch to a hexavalent chrome-free system while maintaining or improving the existing quality.

• PreCoat CPF – Sustainable and cost-efficient pretreatment
  PreCoat CPF is the smart alternative to traditional iron phosphating. It degreases and applies a conversion/passivation layer in a single step, with little to no sludge formation. Operating at lower temperatures (15–30 °C), it reduces energy costs while delivering excellent corrosion protection and paint adhesion on steel, aluminium, and galvanized steel. Phosphate-free and environmentally friendly, PreCoat CPF simplifies wastewater treatment.
• Starter MM & MM31® – The smart replacement for iron phosphating
  Starter MM & MM31® offer an innovative alternative to traditional iron phosphating. This two step solution combines powerful cleaning with the formation of a conversion layer, creating a clean, coating ready surface with strong paint adhesion and corrosion protection. At the same time, the process helps reduce energy, water, chemical use, and maintenance requirements..
