AQUA POLY 250 is a finely micronized polyethylene which has been modified for easy dispersion into aqueous systems such as printing inks, paints and coatings (varnishes). AQUA POLY 250 has been processed to a NPIRI grind gauge reading of 4.0-5.0 for direct incorporation into aqueous systems using high speed mixing equipment. Prior compounding or grinding is not necessary in most cases.
AQUA POLY 250 has been formulated to provide optimum rub resistance, anti-blocking and slip properties when incorporated into aqueous systems. The unique properties of AQUA POLY 250 eliminate the problem of "flotation" or "defoamer kickout" which is common when using most types of conventional micronized waxes or polyethylenes in aqueous systems.
Additions of 0.5-2.0% (by weight) will provide optimum performance. The level of addition will depend on the end use requirements. AQUA POLY 250 also exhibits excellent gloss retention properties.
AQUA POLY 250 is recommended for use in the following areas:
Flexographic (paper or film), packaging gravure (paper or carton) and publication gravure printing inks; water reducible wood finishes, coil coatings, industrial finishes and latex paints; aqueous coatings for two piece cans and offset printed folding cartons or paper (Dahlgren, Epic, etc.); aqueous overprint varnishes.
