NEOBENT PV is bentonite clay powder for aqueous non-stick coatings.

NEOBENT PV is developed as a suspending additive for aqueous non-stick coatings used in the painting of sand foundry moulds and cores.

NEOBENT PV provides sedimentation and aggregative stability of refractory filler, i.e. prevents rapid separation of suspensions and the formation of hard-to-mix precipitates.

NEOBENT PV is produced in two grades according to TU 08.12.22-030-41219638-2024: standard grinding and ultra-fine grinding for better dispersion in water coating compositions.
