Description / Abstract:

Material Description. This standard gives performance requirements for organic-coat finishes on the surfaces of underhood and underbody components. It also gives opportunity to specify the type of coating material to be used.

Symbols. Not applicable.

Applicability. These coatings are typically used on chassis components, as well as other underhood and underbody components.

Remarks. Eight types of paint are covered by this specification: Types A and B are both cathodic e-coats in two different thickness ranges. Type C is dip primer other than cathodic e-coat. Type D is powder coating. If Type E is specified, the applicator is free to choose Type A, B, C or D but must stay with this choice. Type F is to be further specified on the drawing using notes or a paint material specification. Type G is solventor water-based, spray-applied paint. Type H is a dip or dip spin high-performance coating commonly specified for high-strength control arms, links and cradles/framing. Type H coatings are normally used on bare steel substrates
