Symbols.

Not applicable.

Applicability.

This coating is used to improve the chemical resistance of formed aluminum trim parts (window moldings, roof rack rails, etc.)

Remarks.

This coating may be used to meet the Decorative Exterior Colored/Transparent (DEC/DET) requirements of GMW14665-DEC-Class A and GMW14665-DET-Class A. For conventional anodize and seal (without topcoat), see GMW14665-DET-Class B. For inorganic clearcoat over anodizing, see GMW16209.
