Introduction
WQ-290 is a non-film forming hard styrene-acrylic copolymer
emulsion specially formulated for
waterborne overcoat varnishes and printing inks. The varnish
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 by itself, it must be used with a suitable
film-forming additive or mixed with a
film-forming acrylic emulsion with a smaller particle size. In
addition, this product has good
pigment wetting in flexo and gravure inks ability.
