Overprint varnishes (OPV) need good film-forming properties along with block resistance and a variety of other resistances. Styrene acrylic RSE polymers are often a best choice when formulating an OPV. For example, these emulsion polymers can be formulated into a non-skid or high gloss OPV.
Rovene® 6114 is a low glass transition temperature, acrylic polymer emulsion with improved oil & grease resistance. It is a very soft film forming vehicle that provides good gloss, excellent water and rub resistance, and non-skid properties for flexographic and gravure inks and overprint varnishes.
Rovene 6202 is a general use styrene-acrylic resin solution that is used as a grinding resin to produce pigment dispersions. The solution can also be used as an additive to modify certain properties of an ink or overprint varnish.
Rovene 6201 is an alkali soluble styrene-acrylic resin with a mid-range molecular weight for overprint varnishes, water based inks and pigment dispersions
Rovene 6204 is a 34% solids solution version of Rovene 6201 styrene-acrylic resin neutralized with ammonia hydroxide. It can be used as a pigment dispersant resin and as a modifying additive in inks or overprint varnishes.
Rovene 6107 is a very hard, resin supported emulsion but has a minimum film forming temperature below 20°C that is designed to be used as a letdown vehicle in inks and overprint varnishes for paper and paperboard substrates.
Rovene 6104 is a very soft, film forming vehicle that provides good water and rub resistance for flexographic and gravure inks and overprint varnishes.
Rovene 6103 is a styrene-acrylic resin supported emulsion can be used as the film forming component in overprint varnish formulations or as the sole vehicle for inks and overprint varnishes.
Rovene 6102 is a hard, film forming vehicle with a moderately low glass transition temperature (Tg) for flexographic and gravure inks and overprint varnishes, that exhibits good water resistance
Rovene 6112 is a hard, film forming, low glycol and VOC vehicle with a moderately low glass transition temperature for flexographic and gravure inks and overprint varnishes.
Rovene 6106 is a low viscosity but high solids letdown emulsion for paper and paper board substrates.
Rovene 6101 is a non-film forming, high gloss extending vehicle for flexographic and gravure inks and overprint varnishes. It is intended primarily for use on paper and paperboard substrates.
Rovene 6111 is a low glycol and low VOC styrene-acrylic resin supported emulsion. It is a general purpose, hard, non-film forming emulsion for flexographic and gravure inks and overprint varnishes.
Rovene 6115 is a styrene-acrylic resin supported emulsion. Rovene 6115 is hard, non-film forming vehicle that is neutralized with sodium hydroxide for flexographic and gravure inks and overprint varnishes primarily for use on paper and paperboard substrates.
