GMW17190

Description / Abstract: Material Description. This standard covers the requirements for a coil coated aluminum sheet for exterior hardware applications. The coating systems indicated consist of:

a. a urethane primer, a fluorocarbon color coat and, where indicated, a compatible fluorocarbon or urethane clear coat or,

b. a proprietary aluminum oxide anodic layer and a clear fluorocarbon topcoat or,

c. a proprietary aluminum oxide anodic layer, a fluorocarbon color coat and a clear fluorocarbon topcoat.

The organic coatings are applied by reverse roll coating. Various systems which correlate to coating thickness, color, and gloss are identified by codes, as shown in Table 1. Due to lower film builds, Code H and Code I may not be appropriate for some high wear applications. Some applications requiring high elongation may be inappropriate for this material as whitening of material may occur. Each part needs to be evaluated on an individual basis.

Symbols. Not applicable.

Applicability. Interior or exterior formed aluminum trim parts such as roof ditch moldings, side window division posts and pillar appliques.
