  • 10. Painting and Printing Urethane, epoxy, acrylic, polyvinyl chloride acetate copolymer and phenol resin paints can all be used. Acrylic cold setting paints are recommended. For printing, acrylic, chlorinated rubber, polyvinyl chloride and polyamide inks can be used, while chlorinate rubber and polyamide inks are preferred. When choosing a paint or printing ink, take a special note of chemical composition, especially the type and concentration of the thinner or carrier that is used. Removing paint or other materials Freshpaintmayberemovedbyrubbinglightlywithacleaningmaterialsuchasisopropylalcohol.Thenthesheetshouldbewashedimmediatelywithamildsoapordetergentinwarmwater,andrinsedthoroughlywithcleanwater.

Pre-heating is also effective in creating an efficient forming cycle with uniform result.
