SST®-4 is a white low MW PTFE micropowder with particle size distribution at a mean value of 3-4 µm.
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.
SST®-4P is an off-white to light gray low MW PTFE powder with a particle size mean value of 3 µm.
SST®-4P is used in both the inks and thin-film coatings applications due to its small particle size. SST®-4P is recommended in offset and liquid inks. SST®-4P is also recommended for use in powder, water-based, solvent-based, and UV coatings.Typical applications include can and plastic coatings.
