LithoGard EXTRA DULL sheetfed conventional overprint varnish is Kerley's premium, no-gloss, low-color overprint varnish for the highest quality applications that require a non-yellowing finish. LithoGard SST contains PTFE, so dried films have acceptable scuff resistance after drying 30 minutes from impression. LithoGard EXTRA DULL “flat” 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 after impression to a very hard, yet flexible and more chemically-resistant film. LithoGard DULL, when properly applied and adequately air-cured, is capable of withstanding rub tests of several dozen strokes. LithoGard DULL contains cobalt drier, so it will form a skin when it is exposed to air. Contains PTFE powder and 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
