​Thermagard™ HQ SATIN Heatset OPV

ThermaGard HQ SATIN heatset overprint varnish is Kerley's premium, semi-gloss overprint varnish. ThermaGard HQ SATIN contains PTFE, so dried films have good scuff & burnish resistance right from the delivery end of the press. ThermaGard HQ SATIN formulated to be used in the press fountain, just like an ink. This means that ThermaGard HQ SATIN varnish can also be used as a “spot” varnish for selective application of varnish on the printed sheet. 

ThermaGard HQ SATIN also contains Tung Oil (aka: Chinawood Oil), enabling the film to continue to air-cure after heat-setting to a very hard, yet flexible and more chemically-resistant film. Consequently, ThermaGard HQ SATIN OPV does not accept lamination or stamping readily (please see our wax free offerings). ThermaGard HQ SATIN, when properly applied and adequately air-cured, is capable of withstanding rub tests of several hundred strokes, especially if a small amount of drier such as our “Litho Dri CO 6” is added press-side. Contains PTFE and silica, which must be stirred from the bottom of the container before usage.

ThermaGard HQ SATIN contains 41% bio/renewable materials.
