GMW 14674:2017

Material Description. This coating can be an organic electrostatically applied powder epoxy paint or liquid applied paint.
Symbols.
• Type A. Electrostatic Applied Epoxy Powder Coating. Only epoxy materials are approved for this type coating. Other paint technologies may be suitable and shall require validation to assure conformance to durability, machinability and topcoating specifications.
• Type B. Liquid Applied Paint Film.
Applicability. This coating is suitable for medium to large parts in underhood and underbody applications where protection from ultraviolet (UV) light exposure is not required. The resultant paint film is intended to provide cosmetic corrosion resistance to exterior surfaces of cast iron components, e.g., cylinder heads and blocks.
Remarks. This standard covers the performance requirements for organic paint finishes to underbody/hood parts for cast iron parts.
