SST®-4 is a white low MW PTFE micropowder with particle size distribution at a mean value of 3-4 µm.
SST®-4
SST® products are Shamrocks 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®-4 is a white low MW PTFE micropowder with particle size distribution at a mean value of 3-4 µm.
Application:
SST®-4 is frequently used in both the inks and thin-film coatings applications due to its small particle size. SST®-4 is recommended for use in offset and liquid inks. SST®-4 is also recommended for use in powder, water-based, solvent-based and UV coatings at 0.5-3.0% of the total formula weight.Typical applications include can and plastic coatings.
