Micronized Wax for Inks and Coatings
Micronized waxes are used in printing ink to provide rub resistance while maintaining over-printability. Gloss and slip are other considerations in the selection of wax. In coatings, wax provides mar and abrasion resistance. (Re-coatability, slip, gloss retention or matting, clarity and overall surface properties are important.)Shamrock produces a full line of micronized waxes: natural, synthetic, and blends that impart specific physical properties. These compositions cover a range of properties to suit various applications. We offer these as products in a range of particle sizes as described by their stir-in reading on NPIRI and Hegman grind gages. A reading of 10 on the NPIRI grind gage equals 25 microns. N5 =12.5 microns, N3= 7.5 microns, etc. We also use instrumentation that measures particle size distribution.

Hydrophillic Synthetic Wax Powders
Powders can be made wettable with wetting agents. The Neptune products are composed of hydrophilized synthetic waxes, thus making them excellent for polar systems.
