Pel-Plug TR30  3/8" Coated 

  • A clean, virtually odorless and easy to handle Bentonite pellet which combines the high quality yield of western Bentonite with a biodegradable nonsticking coating.
  • The coating, developed by PDSCo, allows the pellets to be poured through standing water without sticking together, eliminating voids and bridging.
  • Pel-Plug TR30 has the same ability to absorb water and maintain the 8-12 times expansion pattern that has been typical of the regular Pel-Plug Bentonite pellet.
  • Pellets should be allowed to hydrate for at least 2 to 3 hours depending on water quality.
