The requirement profile for the pre-treatment process changes continuously in surface finishing. In addition to pure functionality, cost considerations, process reliability, the consistent achievement of quality standards and product sustainability are becoming increasingly important. It is precisely these factors that enable a user to differentiate and position himself in his respective market environment.

This is why SurTec is concentrating primarily on a new generation of processes in the development and marketing of its special chemicals for metal pre-treatment. These are generally characterised by their ease of use, industrial robustness, possibilities for precise process control and, above all, optimised process costs, while at the same time maintaining extremely stable quality values.

CY-50 Aluminum Passivation

CY-50 offers unmatched corrosion resistance in uncoated condition, low surface resistance, and superior adhesion base for subsequent coatings. It is considered the industry benchmark for aluminum pre-treatment and is highly recommended for use in the Automotive, Electronics & Electrical, and Aerospace industry.

Multi-Metal Pre-Treatment Phosphate Alternative

The phosphate-free CY-Series pre-treatment achieves corrosion protection properties comparable to traditional zinc phosphatings. Additionally, it minimizes flash rust formation and maximizes resistance against contamination during operation.

High-Performance Chrome-free Conversion Coating for Aluminium

xxx is especially characterised by the fact that filiform corrosion and paint adhesion remain within the specifications without any problems even in strongly aged and contaminated baths. During the development of this technology, the main focus was put on an optimised process and quality control for bath and final product.

Next Generation for Pre-treatment of Aluminium Wheels

Aluminium wheels are becoming increasingly popular with car owners all over the world. They convince above all through their extraordinary design. Of course, aluminium wheels must also meet the highest demands of car manufacturers in terms of corrosion and weather resistance. Therefore, SurTec has developed the innovative technology xxx, a process which not only fulfils all quality requirements - even for machine faced wheels - at the highest level, but also offers the wheel manufacturer the possibility to realize significant cost advantages by saving energy in the cleaning step and reducing maintenance efforts in all process steps.
