CLAYTONE-AF

CLAYTONE AF is an organophilic bentonite derivative which is used as thixotropic thickener and anti-settling agent in solvent based coating systems of low to medium polarity. CLAYTONE AF is easy to disperse and self-activating. A specially activated, organophilic smectite product, CLAYTONE AF can swell in organic media and build a gel structure (card-house structure). Weak hydrogen bonding between the single smectite platelets is the reason for this thixotropic gel structure. Therefore, the complete separation of the platelets (complete dispersion of agglomerates into primary particles) is necessary for optimum efficiency. CLAYTONE AF is designed as an easy-to-disperse, self-activating rheological additive for low to medium polarity solvent-based coating systems. It prevents sagging and settling in resin-based systems. CLAYTONE AF is not effective in products without binders, such as lubricating grease or pure solvents. In rust inhibitors based on salts of oxidised petrolatum CLAYTONE AF can be used. Further applications include trade sales, wood stains, printing inks, architectural paints and do-it-yourself paints.
