Substitute To Joncryl 90 Hard Non-Forming Low Viscosity
Styrene-Acrylic Copolymer Emulsion
WQ-2090L Water Based Acrylic Emulsion
Introduction
WQ-2090L is a hard non-film-forming styrene-acrylic copolymer
emulsion specially formulated for water-based overprint varnishes
and printing inks. The OPV formulated with this product has fast
drying speed and high gloss, excellent water resistance and
anti-stick back performance, and it has good compatibility with
popular acrylic polymers on the market. Since this product cannot
form a film alone, so it must be used with a suitable film-forming
aids or mixed with a film-forming acrylic emulsion with a smaller
particle size, such as used with our film-forming varnish emulsion
WQ-2027, WQ-2024, WQ-2018, WQ-2015, etc. In addition, in flexo and
gravure inks, the product has good pigment wetting.
WQ-2090L is low-viscosity version of WQ-2090, it is has low
viscosity and is spefically designed for replacing Joncryl 90.
WQ-2090L has excellent gloss and transparency and quicking drying,
it is highly recommended for water-based overprint varnishes
and flexographic and gravure-printing inks.
