Description

Zinc Silicofluoride is an inorganic salt primarily valued for its role as a durable source of fluoride and zinc ions in industrial processes. Its key commercial value lies in providing effective surface treatment and hardening properties for a variety of substrates. This compound is essential for manufacturers in the construction, ceramics, and metal finishing industries seeking to enhance material performance and longevity.

Application

• Concrete Hardener and Waterproofer: Used to densify and harden concrete floors and surfaces, improving abrasion resistance and reducing dusting.
• Metal Surface Treatment: Acts as a component in formulations for galvanizing fluxes and metal pretreatment to improve coating adhesion and corrosion resistance.
• Ceramics and Enamel Opacifier: Employed in the production of ceramics, porcelain, and vitreous enamels to enhance opacity, gloss, and durability.
• Wood Preservative: Serves as an active ingredient in formulations designed to protect lumber from fungal decay and insect infestation.
• Laundry Sour and Water Treatment: Used in industrial laundries as a souring agent to neutralize alkalinity and in water treatment for fluoridation.
• Manufacturing of Other Fluorides: Acts as a key intermediate or raw material in the synthesis of other complex fluoride compounds.

Quality Control

Our Zinc Silicofluoride is manufactured under strict quality management protocols to ensure batch-to-batch consistency and reliability. The product undergoes comprehensive analytical testing, including assay, impurity profiling, and physical characterization. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and degradation. Recommended storage temperature is between 15°C and 25°C.
