Claytone 40

Claytone 40 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 40 is a traditional organoclay requiring the addition of an activator to achieve full efficiency. As an organophilic smectite product, Claytone 40 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. For optimum efficiency the complete separation of the platelets (complete dispersion of agglomerates into primary particles) is necessary. Claytone 40 prevents sagging and settling in resin-based systems. In heavy duty coatings and rust inhibitors based on salts of oxidized petrolatum Claytone 40 can be used. Further applications include trade sales, wood stains, printing inks, architectural paints, do-it-yourself paints, etc.
