We have a state-of-the-art clear chemical coating facility onsite, which negates reliance on outside contractors and enables us to process parts 24/7.

This process has been built around our customers’ requirements and is approved to AS9100 Rev D.

The current preferred clear chemical coating offered is Surtec 650, however alternatives are available if required.

By using SurTec 650, a chromium-free passivation for aluminium, we can conduct high quality industrial cleaning. SurTec 650 is a high-value chemical product, which is primarily used in the electronics, automotive and aerospace industries, as well as in the electroplating industry where it can be either pre-treatment or post-treatment.

SurTec 650 Properties:

  • Hexavalent chromium free passivation for aluminium
  • Suitable as post-treatment of anodic coatings
  • Suitable as conversion coating of magnesium
  • Liquid concentrate, based on trivalent chromium
  • Excellent bare corrosion protection comparable to hexavalent passivations
  • Works on alloyed and casted aluminium
  • Suitable as pre-treatment before lacquering, powder coating and gluing
  • Approved by GSB and QUALICOAT
  • Easy to handle in immersion, spray and wipe, application produces an iridescent, faintly blue to tan visible layer
  • Meets or exceeds MIL-DTL-81706B and MIL-DTL-5541F for bare corrosion (336 h in NSS per ASTM B-117, respectively, DIN EN ISO 9227)

The Exact Group has the ability to tailor the process to suit our customers’ requirements and specifications, ensuring that a quality coating is achieved each and every time.
