Description

Silicic Acid, Zinc Salt CAS NO 11126-29-7 is an inorganic compound formed from zinc and silicic acid, valued for its unique combination of zinc's functional properties and the thermal stability and reinforcing characteristics of silica. This material is essential for industries requiring specific catalytic, reinforcing, or flame-retardant effects. It serves as a critical functional additive and catalyst precursor in rubber manufacturing, polymer composites, and specialty chemical synthesis.

Application

• Rubber Industry: Acts as a reinforcing agent and activator in the vulcanization process for tires and industrial rubber goods, improving mechanical properties.
• Polymer Composites: Used as a filler and flame-retardant synergist in plastics and elastomers to enhance thermal stability and reduce flammability.
• Catalyst & Catalyst Support: Serves as a precursor or active component in catalysts for organic synthesis and petrochemical processes.
• Ceramics & Glass: Employed as a modifying agent to influence the thermal expansion and opacity of specialty glasses and ceramic glazes.
• Coatings & Paints: Functions as a matting agent and corrosion inhibitor in protective coating formulations.
• Adhesives & Sealants: Provides thixotropic properties and improves bond strength in high-performance adhesive systems.
