TS421 is based on engineering thermoplastics, specifically designed for extremely low friction in lubricated conditions under low loads but presenting good characteristics in dry low load conditions as well. This system comprises a primer layer and an active hybrid top-coat. TS421 is part of the standard TriboShield® product range.


  • Pumps
  • Hydraulic motors
  • Precision linear guides
  • Extremely low friction in lubricated condition
  • Very low friction in dry conditions at low loads
  • Excellent chemical resistance

TriboShield® coatings are applied directly to the customer’s part and are suitable for complex geometries as well as various substrates e.g. steel, stainless steel, Al, Ti, Mg, etc. They can be used for both interacting surfaces that are in relative motion.
