Title - Use of Rheological Clays in Water Based and Solvent Based Systems

Abstract - Specialty rheology modifiers from Tolsa include Sepiolite, Attapulgite and Bentonite. These clays are used in water based and solvent coatings to provide rheological properties. Because of the special structure of these clays they provide viscosity, antisettling and antisagging properties. These clays are thixotropic and pseudoplastic which provide for easy pumpability. They are used as partial/complete replacements with other rheology modifiers such as Heur, Acrylic thickeners and Cellulosics. These clays can be provided in activated form to replace fumed silica (pyrogenic silica) for solvent based coatings for cost savings. The unique structure, surface area and silanol density of these groups provide excellent rheological properties for w/b, s/b coatings and cementitious products.

Bio - Emmanuel Durant is the North American, Central American and Caribbean Sales Manager for the Additives and Filler Market for Tolsa. He is in charge of promoting specialty clays for rheology applications in the ACES and Construction market. Emmanuel has a B.S Degree in Business Administration from Cal State Univ of Northridge and is finishing up his MBA in December from University of Northwestern Ohio. He has spent the last 4 ½ years working for Brenntag Specialties on the West Coast as an Account Manager and Corporate Account Manager.
