Material Description. This specification describes five different low-friction coating materials and their performance on various plastic combinations known for creating Noise, Vibration and Harshness (NVH) issues.

The low-friction coatings qualified to this specification shall be listed by type with recommended applications for controlling squeak and itch conditions.

Type I. A sprayable coating which yields excellent non-friction properties over a wide variety of substrate combinations. The Type I coatings maintain a greasy, semi-liquid state which can transfer to clothing and should only be used in areas of the vehicle where no contact with passengers is possible.

Type 2. A translucent, water-based coating which can be sprayed or brushed and is recommended over a wide variety of substrate combinations.

Type 3. A clear, solvent-based coating which can be sprayed or brushed on and is recommended over a wide variety of substrate combinations.

Type 4. A milky, water-based coating which can be sprayed or brushed on and can only be recommended for a few substrate combinations.

Type 5. A milky, water-based coating which can be sprayed or brushed on and can only be recommended for a few substrate combinations.

Symbols. Not applicable.

Typical Applications. Applications where two substrates rub against one another to create undesirable noise.

Remarks. Recommended applications are based on data generated from GMW16321 testing completed on all substrate combinations. All substrate combinations are then retested with each type coating listed in paragraph 1.1 of this specification.
