This specification covers the basic requirements for a corrosion protective coating system for spring hose clamps per GM6298M. This coating is resistant to strong oxidizing corrosives and provides excellent adhesion properties for glued on clamp applications.

Material Description.

The coating system is free of hexavalent chromate and is in compliance with GMW3059 requirements.

The coating system does not induce hydrogen embrittlement.

Typical Applications.

The coating is suitable for constant tension clamps. The maximum continuous service temperature is 200°C.

Remarks.

Use of this coating system on threaded surface and/or bearing surface of joints could effect the torque-tension relationship. It is recommended that a torque-tension study of the fastener joint be performed before releasing this finish on any new application.
