Aluminum

AD Chemicals supplies a range of products for the pre-treatment prior to powder coating, liquid painting and passivation of aluminum substrates. 

Pre-treatments:

AD Chemicals produces and supplies a range of products to prepare the surface of substrates prior to powder-coating that enhance adhesion and the surface quality of the finished product. These products can be applied in dip, spray and cascade processes.

These products include:

  • Degreasers, Etch, Etch additives, desmut/neutralisation, chromate based products and chrome free products (Chrome-free PRECOAT products meet and exceed the ‘Qualicoat stated requirements and are Qualicoat and GSB approved)
  • AD Chemicals supplies a range of paint-strippers for aluminum

Passivation:

Oxidation is the enemy of aluminum strip and profiles; it is in itself a form of corrosion that occurs during storage and is unacceptable for critical applications in automotive, aviation, white goods, construction and in other industries.

Passivation treatments, that are applied in-line, form a barrier to corrosion and form a suitable layer for post painting operations. Passivation products are both economic and effective in use. AD Chemicals broad based knowledge and experience is available as a development service such that customers specify their passivation requirements tailored to the substrate type and application process.
