Australian Chemicals and Coatings are pleased to annouce that we are now authorised Pre-Treatment and Anodising distributors for SurTec. SurTec develops, manufactures and supplies chemical specialities for surface finishing.

With its three fields of application – Industrial Parts Cleaning, Metal Pre-treatment and Electroplating – SurTec offers a highly comprehensive portfolio in this sector. SurTec supplies almost all segments dealing with surface treatment, including automotive, aerospace, construction/architecture, household, electronics, renewable energies, and mechanical engineering industries. In 2010 the Freudenberg Group took over the shares of SurTec International. This resulted in SurTec becoming the 4th division of Freudenberg Chemical Specialities Company. They've now established a dedicated research group for Metal Pre-treatment.

SurTec 609 GV  

SurTec 609 GV is based on trivalent chromium and is suitable as multi-metal passivation prior to painting steel, aluminium, HDG and EG zinc die cast. This Phosphate free Pre-Treatment is especially designed for subsequent anaphoretic or cataphoretic paint and produces uniform nano-size layers. It gives perfect adhesion of lacquers, excellent corrosion protection, has no or very low sludge formation, only requires a low process temperature and is especially robust again flash corrosion.

SurTec 640

SurTec 640 is a no-rinse chromium-free conversion coating for aluminium. It’s suitable for use prior to powder respraying, wet painting and chemical respraying, adhesive bonding and is the optimal pre-treatment for adhesion and corrosion resistance. SurTec 640 is the global No. 1 chromium-free technology for aluminium that forms a colourless conversion layer and is applicable in spray and flooding application in horizontal and vertical lines as well as in immersion application. It has a proven track record as aluminium pre-treatment in the building, automotive supplier, electronics and wheel industry. It enhances the corrosion resistance when used as post-seal for phosphate alternative or phosphate layers. This special product is based on Bulk Chemical Technology and is proven to be a far more environmentally friendly method in terms of waste treatment and is economically easier to dispose of.

SurTec 650

SurTec 650 is a Chromium(VI)-Free Passivation for Aluminium for the Electronics, Automotive and Aero-space industry. It’s a liquid concentrate based on trivalent chromium, which is suitable as conversion coating of magnesium and as a post-treatment of anodic coatings. This specific SurTec product is used as a pre-treatment before lacquering, powder-coating and gluing. It has excellent bare corrosion protection comparable to hexavalent passivations and works on alloyed and casted aluminium, whilst being easy to handle in immersion, spray and wipe application.
