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. It is a traditional organoclay requiring the addition of an activator to achieve full efficiency. As organophilic smectite product, it 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.
