GMW15196

Description / Abstract: Material Description. This specification covers two types of high-temperature resistant, anti-corrosion coating. Type A is a black coating that is usually applied by a spray operation. It is capable of withstanding temperatures up to 450 °C without a loss of corrosion-resisting properties. Higher test temperatures are permissible in consultation with the responsible Materials Engineer. Type B coating can withstand high temperatures up to 600 °C without adverse effects.

Note: Type B should not be specified on vehicles that are intended for use in countries that apply salt to roads in winter.

Symbols. Not applicable.

Typical Applications. These coatings are typically used for visible exhaust system components such as tailpipes and the side and bottom portions of mufflers and may be applied to stainless steel, aluminized stainless steel, or aluminum.

Remarks. Only the substrate/paint combinations that are shown in the Approved Source List shall be used. When material approval testing is performed, each test must be completed on a minimum of three panels.
