PTFE Micropowder

SST® products are Shamrock’s PTFE micropowders that are defined by particle size and distribution, molecular weight, crystallinity, surface area, oil adsorption, powder flow, and color. Made primarily from highly controlled recycled PTFE feedstocks, SST® products are used for their ability to provide slip, non-stick, water repellency, texture, release, rub, and abrasion resistance to surfaces.

Product Description

SST®-2 is a white low MW PTFE micropowder with particle size distribution at a mean value of 8 µm.


SST®-2 is recommended for use in water-based liquid inks, powder coatings, and water-based, solvent-based and UV coatings at 1-3% of total formula weight when used alone, or at 0.5-1% when used with 2-3% synthetic wax.
