Released by Micro Powders, Inc.

August 12, 2013

POLYSILK 750 is a finely micronized polyethylene that has been specifically modified to provide a combination of toughness, abrasion and block resistance while imparting a silky feel and surface lubricity to printing inks and coatings.

POLYSILK 750 is micronized to a NPIRI grind gauge reading of 2.0-3.0 for easy incorporation into solvent, oil, or waterborne systems by means of a high speed disperser.

POLYSILK 750 has been formulated to be used as the sole additive in order to provide maximum surface protection and a smooth feel which eliminates the need for other additives that are used to achieve this combination of properties.

Additions of 1-3% by weight are suggested for best performance. However, the level of addition will depend on end use requirements. Due to the unique nature of this product, the optimum effect of a smooth silky feel will be reached approximately 12 to 24 hours after application while all other surface protection characteristics are realized immediately.

POLYSILK 750 can be used in all types of printing inks, paints and coatings. However, it is especially recommended for use in the following areas: solvent and water based printing inks, lacquers and coatings applied on non-porous substrates, wood and leather finishes, coil coatings, industrial finishes, can coatings and low energy heat-set cover inks.
