USE & PERFORMANCE
Outstanding properties: Provides a combination of abrasion, scratch and heat resistance while
imparting a smooth silky feel and surface lubricity to paints, printing inks, and coatings. It is
micronized to a NPIRI grind gauge reading of 3.5-4.5 for easy dispersion in a solvent, oil, or
waterborne systems.
Recommended for products: Can be used in all types of printing inks, paints, and coatings. How-
ever, 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 coat-
ings, industrial finishes (including plastic, metal), can coatings and low energy heat-set cover inks.
Concentrations used, wt%: 1-3
