: It provides structural reinforcement and controls flow during application.
: One of its most valued traits is its ability to change the viscosity of liquids. It creates a "thixotropic" effect—liquids become thinner when stirred or agitated but thicken back into a gel-like state when left still.
, which allows it to interact effectively with other substances.
: It acts as an anti-sagging agent, preventing paint from dripping off vertical surfaces.
While fumed silica is not classified as a carcinogen, it is an due to its fine particle size. Prolonged or high-level exposure can irritate the respiratory system and eyes. Consequently, safety protocols typically require the use of protective masks and ventilation when handling the dry powder in industrial settings. CAS 112945-52-5: Silica, amorphous, fumed, cryst.-free
