POLYFLUO 400 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 400 has been micronized to a 1.0-2.0 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 POLYFLUO 400. At low levels, POLYFLUO 400 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 400 is used as the sole slip additive. In some cases, more desirable slip properties are achieved by adding the POLYFLUO 400 in combination with micronized waxes or polyethylenes. When used in combination with the above types, a 2:1 ratio (wax or polyethylene: POLYFLUO 400) is recommended. A concentration of 1/2-1% by weight of the POLYFLUO 400 is recommended when it is used in combination.
At temperatures above 600°F some polymer fumes may be emitted due to decomposition of the fluorocarbon polymer. Therefore, smoking should not be permitted when working with this material.
