Hicoat 74
ACRYLIC EMULSION
Summary
Hicoat 74 is a soft film forming polymer used as modifier
in overprint varnishes and as the letdown vehicle to provide
adhesion to film and substrates. Having good pigment wetting
and viscosity stability allows it to be used in the grind
stage of dry pigment dispersions. It is suitable for printing
on Films and Foils.
Characteristics
- Good viscosity stability
- Good pigment wetting
- Low foaming – good compatibility with defoamers
- Excellent Rheology properties – good transfer
& printability
- Good grease & water resistance
- Good ice crinkle resistance
- Good adhesions to a wide variety of flexible films
that have been corona tested to a minimum of 35 dynes

Compatibility
Hicoat 74 is not as readily compatible with some of the
alcohols (isopropanol and ethanol) but is compatible with
n-propanol and other glycol ether solvents. Predilution
with water is recommended.
Packaging
Available in 200kgs drums normally.
Shelf Life
Store under cool, dry conditions. It is recommended that
the material should be used within 10 months of certification.
