When doing plastic working of a pre-coated aluminum sheet, wax is added to the paint as inner wax, or wax is coated on the pre-coated film as outer wax, for the purpose of ensuring surface lubricity. In the case where two or more kinds of wax are used simultaneously and the coated film is subjected to baking or other kind of heat treatment, interactions will take place between these waxes. However, there have been few studies about this.
This study melted and mixed carnauba wax and polyethylene wax, and carnauba wax and paraffin wax, and investigated their behavior. As a result, the study found that these waxes show new physical properties when melted and mixed, that is, these mixtures offer excellent lubricating performance by melting and mixing.
