Should the presence of a restricted substance in paint (prior to processing) from a supplier be reported on the W18?
A material safety data sheet (MSDS) obtained from a paint supplier indicates the presence of a restricted substance that exceeds Motorola’s reporting threshold. The paint, prior to spray application onto a plastic substrate, contains 2.1% of Ethylene Glycol Monomethyl Ether and its acetate. This exceeds the Motorola reportable limit of 5 ppm. According to W18 specifications and the Compliance Connect report, process chemicals and other substances that do not remain with the part received by Motorola should not be included. Often, the solvents in paint evaporate during processing and no longer remain in the paint film. so, if the substances have completely evaporated from the coating during processing, these chemicals do not have to be reported to Motorola. However, if tests of the finished part show the restricted substance is still present in the coating in an amount at or above the reportable level for that chemical, then it should be reported.
