Minerals Used for Adhesives & Sealants Industry

Minerals play a critical role in adhesives and sealants, enhancing viscosity, adhesion, durability, and thermal resistance. These minerals act as fillers, rheology modifiers, and reinforcement agents, improving the performance, workability, and longevity of adhesives and sealants. Minerals like Talc, Calcium Carbonate, Dolomite, Lime, Kaolin, Quartz, Feldspar, Bentonite, Barytes, and Mica contribute to better bonding, stability, and cost efficiency in formulations.
