Mekoprint is able to deliver customised solutions and so handle all stages of production. This means that we also deliver solutions in connection with the surface treatment of aluminium and other workpieces – including passivation with SurTec 650 as a surface treatment of aluminium.
SurTec 650 is a trivalent chromium compound for the surface treatment of aluminium, achieved through a dipping process. The treatment is electrically conductive and an excellent pretreatment prior to powder coating. The process complies with the corrosion requirements of MIL-DTL-81706-B and F-MIL5541. The colour is transparent to slightly blue/purple.
Amongst other things, the advantages of SurTec 650 are that the corrosion properties are improved, the surface’s electrical conductivity is retained and the aluminium’s binding capacity for, e.g. paints, adhesives and lacquers is increased.
Mekoprint is available for questions about the surface treatment of aluminium and SurTec 650 products – so, please do not hesitate to contact us.
