SST® 4D

1 of 33 products in this brand
SST®-4D is a white low MW PTFE powder with a particle size mean value of 3 µm. SST®-4D has a tightly controlled particle size distribution, resulting in fewer oversized particles. 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.

Functions: Anti-Abrasion Agent, Slip Agent

End Uses: Offset Ink, Powder Coating, Radiation Curable Coating, Solventborne Coating, Solventborne Ink, Waterborne Coating, Waterborne Ink
