Organophilic Bentonite Rheological Additive BT-383

BT-383 is an advanced, self-activating organoclay engineered for medium-to-low polarity systems as an upgraded alternative toBT-185. While retaining superior thixotropic thickening and anti-sagging performance, it features exceptional ultra-dispersion, selfactivation, and high clarity with low gel color. It eliminates the need for polar activators or pre-gels, making it widely ideal for premium paint, ink, cosmetics, and sealants, while effectively serving as a high-performance alternative to fumed silica.
