Bentone 38

BENTONE 38 rheological additive is the oil service industry's standard for a high temperature/high pressure performance organoclay. This additive is manufactured with a high efficiency hectorite clay noted for imparting superior heat stability. BENTONE 38 exhibits an excellent balance of dispersibility and efficiency. BENTONE 38 performs well in diesels, mineral oils, poly, linear and isomerized alpha olefins and vegetable oil derivative base fluids Key applications: • increases viscosity • provides thixotropy • prevents pigment settling during storage • improves flow and leveling • controls sagging on vertical surfaces and penetration on porous substrates • prevents syneresis in thixotropic systems.
