SurTec® 650 treatment

SurTec® 650 is a chromate conversion coating of aluminum based on chromium (III: trivalent chromium) and complies with the RoHS III(1) (Restriction of Hazardous Substances in Electrical and Electronic Equipment) Directive and ASTM B449-93(2), MIL-DTL-81706 B(3) and MIL-DTL-5541F Type 2.

The SurTec® 650 treatment allows the protection of aluminum surfaces to be achieved, avoiding the use of subsequent treatments.
This anti-corrosive treatment is widely used:

– As a primer for preparing the metal surface, improving the adhesion of the subsequent painting phases and, more generally, increasing adhesion even when using lacquers, enamels and other types of coatings;

– To improve the environmental resistance of aluminum by maintaining good surface conductivity and thus preserving the electrical properties of this metal.
