LithoGard EXTRA DULL sheetfed conventional overprint varnish is Kerley's premium, low-gloss, low-color overprint varnish for the highest quality applications that require a non-yellowing finish. LithoGard EXTRA DULL contains mainly polyethylene wax, plus a little PTFE, so dried films have good scuff resistance. LithoGard EXTRA DULL OPV is formulated to be used in the press fountain, just like an ink. This means that LithoGard EXTRA DULL varnish can also be used a “spot” varnish for selective application of varnish on the printed sheet.
LithoGard EXTRA DULL also contains Tung Oil (aka: Chinawood Oil), enabling the film to continue to air-cure to a very hard, yet flexible and more chemically-resistant film. LithoGard EXTRA DULL, when properly applied and adequately air-cured, is capable of withstanding rub tests of several dozen strokes. LithoGard EXTRA DULL contains cobalt drier, so it will form a skin when it is exposed to air. Contains silica, which must be stirred from the bottom of any container before usage.
LithoGard EXTRA DULL will pass Calif. AQMD maximum 300 g/L VOC content requirements, and contains 66% bio/renewable materials.
