ABSTRACT

After removing the protective oil in an organic solvent (methyl ethyl ketone, MEK), the sheets were spray coated with an amino alkyd paint (with green pig­ ment) to a dry film thickness of 15 pm, followed by baking for 20 min at 160 °С in an oven. The ATR-FTIR spectrum of the coated paint is shown in Figure 2, which indicates a typical oil-modified polyester resin, i.e., an alkyd (orthophthalic acid type)/urea-formaldehyde resin.
