Field of Application:
PANOVARSS series are squeeze tube varnish and designed for PE plastic squeeze tube mass production. RSS series may divide into two different type of curing methods. UV curable type of varnish gives fast cure and economizes energy. Solvent type of varnish has low odor and non-yellowing merit. PANOVA® RSS series varnish are advantageous on excellent leveling, water and chemical resistance, flexibility, folding endurance and adherent to PE plastic substrate.
Good in-line stability: No skinning and no dry-up after long-term printing run.
Fast curing performance and good abrasion resistance.
Well stirring before application is required for best performance.
For PE plastic substrate, surface tension of coating surface should be higher than 46 dyne/cm (pre-treatment of corona discharges) .
Minimum of light accumulation consumption for UV curable type of varnish is 150mj/cm2.
Solvent type of varnish must mix according to the proportion before used and place into oven over 70℃ for 15 min.
