Polyfluo®
540XF
POLYFLUO 540XF is a special grade of micronized
modified fluorocarbon which has been developed to provide
maximum slip and lubricity when added to printing inks,
paints and surface coatings. POLYFLUO 540XF has
been micronized to a 1.0-1.5 NPIRI grind gauge reading
for easier dispersion and better gloss properties. Incorporation
into most coatings can be easily achieved with high speed
mixing equipment. There is no need for prior compounding
or grinding due to the fine particle size of the POLYFLUO
540XF. At low levels, POLYFLUO 540XF will impart
a high degree of lubricity along with excellent rub resistance
when added to inks, paints and coatings.
Recommended areas of usage are: heat-set offset, quick
set, ultra-violet and metal decorating inks, overprint
varnishes, as well as, industrial paints such as coil
and can coatings.
Optimum properties are usually achieved by adding 1-2%
by weight when the POLYFLUO 540XF is used as
the sole slip additive. In some cases, more desirable
slip properties are achieved by adding the POLYFLUO
540XF in combination with micronized waxes or polyethylenes.
When used in combination with the above types, a 2:1
ratio (wax or polyethylene: POLYFLUO 540XF) is
recommended. A concentration of 1/2-1% by weight of
the POLYFLUO 540XF is recommended when it is
used in combination.
At temperatures above 600oF some polymer fumes may
be emitted due to decomposition of the fluorocarbon
polymer. Therefore smoking should not be permitted when
working with this material.
