SST® –4P by Shamrock is an off-white to light gray low molecular weight PTFE powder with a particle size mean value of 3 µm. Acts as a slip, mar/scuff, rub and abrasion resistance agent. Provides slip (low COF), high temperature resistance, gloss retention, rub and abrasion resistance properties. 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.
