Hicoat 37
Summary
Hicoat 37 is a nonionic, polyethylene wax emulsion. It
can be formulated into a pigmented or clear coatings to
provide rub resistance and improve slip, without detracting
from gloss or clarity.
Characteristics
- Hardness : The wax emulsion in Hicoat 37, with a
hardness of <0.5 dmm (ASTM method D-5), has outstanding
toughness and scuff resistance.
- Softening Point : The high softening point (ASTM
method E-28) of the wax emulsified in Hicoat 37 is
280F (138C) which contributes to heat and block resistance.
- Compatibility : Hicoat 37 is highly water dispersible
and exhibits good compatibility and stability in aqueous
vehicles.
- Formulating : Typically, Hicoat 37 emulsion is
added at a 5-10% level (1.75-3.5% solids) to water-based
inks or clear coatings. The higher solids of Hicoat
37 emulsion, over competitive emulsified waxes, allows
for more formulating latitude. Adding Hicoat 37 lowers
the coefficient of friction and improves toughness
while maintaining gloss and clarity.
