Protective over-printvarnish (OPV) topcoats
Protective overprint varnishes, used on magazine covers, or for some other printed graphics applications were some of the first UV/light curable products. Due to excellent abrasion, scratch and wear resistance of UV/light curable products they are also often used as protective topcoats.
Photocured low viscosity over coat varnishes are part of Spectra's product base. Contact us for all your varnish over coat needs.
