What is SurTec 650?
SurTec 650 is a chromium-free chemical process specifically developed for the passivation of aluminum and its alloys. Unlike traditional chromate-based treatments, SurTec 650 is free of hexavalent chromium, making it environmentally compliant and safer for users. This product forms a protective conversion coating on aluminum surfaces, ensuring high corrosion resistance and optimal adhesion for subsequent coatings or paints.
Key benefits of SurTec 650
SurTec 650 offers a wide range of benefits that make it an ideal choice for industries looking for high-performance, environmentally-friendly solutions:
-
Chromium-free: Contains no hexavalent chromium, making it compliant with stringent environmental standards like RoHS and REACH.
-
High corrosion resistance: Provides effective protection against corrosion, even in harsh environments.
-
Adhesion promotion: Improves the adhesion of paints and other coatings applied after passivation.
-
Environmentally compliant: A safer alternative to traditional chromate treatments, reducing environmental impact.
-
Cost-effective: Offers competitive costs while ensuring long-term durability and performance.
-
Easy application: Can be applied through spray, dip, or brush processes, offering flexibility for various manufacturing settings.
How SurTec 650 works
SurTec 650 works by forming a conversion coating on aluminum surfaces. The process involves applying a chemical solution that reacts with the aluminum, forming a thin, protective layer that provides excellent corrosion resistance. This layer also enhances the adhesion of subsequent coatings, such as paints or lacquers, ensuring a strong bond and a smooth finish.
The application process is flexible and can be adapted to different production environments. SurTec 650 can be applied via dipping, spraying, or brushing, depending on the specific needs of the component and the manufacturing setup. The process is straightforward, making it easy to integrate into existing production lines without requiring significant changes to equipment or workflow.
Certification and standards compliance
SurTec 650 is fully compliant with international environmental and quality standards, making it an ideal choice for industries that prioritize both performance and sustainability. Some of the key certifications and regulations it adheres to include:
-
RoHS (Restriction of Hazardous Substances Directive): SurTec 650 complies with RoHS regulations, which restrict the use of certain hazardous materials in electrical and electronic equipment, including hexavalent chromium.
-
REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals): The product is REACH-compliant, meeting the stringent requirements for chemical safety and environmental protection within the European Union.
-
MIL-DTL-5541F: SurTec 650 meets the specifications of MIL-DTL-5541F, Class 1A and Class 3, which outlines the standards for corrosion resistance and electrical conductivity in military and aerospace applications.
-
ISO 9001 and ISO 14001: SurTec 650 is produced in facilities that are certified under ISO 9001 for quality management and ISO 14001 for environmental management, ensuring consistent product quality and minimal environmental impact.
