FAQ

Can I request samples or lab testing for my specific application? 

Yes! We offer free samples in crystal or customized powder form, along with COA and lab analysis. Our team can assist with compatibility testing for welding flux, toothpaste, metallurgy, or construction uses to ensure optimal results in your process.

Can I add my logo or label to the packaging?

Yes! Simply provide your logo or label design, and we'll incorporate it into the packaging—helping you maintain brand consistency in your supply chain.

How should Sodium Fluoride be stored to maintain quality across different grades?

Store in tightly sealed containers in a cool, dry place away from moisture, acids, and food items. Its low hygroscopicity ensures excellent stability; proper storage prevents caking and maintains purity for long-term use.

How does Sodium Fluoride perform as a welding flux and slagging medium in metallurgy?

W&Q's high-purity Sodium Fluoride (standard ≥98%, customizable higher) effectively removes oxides, lowers melting points, and improves slag fluidity. This results in cleaner welds with better penetration and higher-quality metal output with reduced impurities in smelting processes.

Is W&Q's Sodium Fluoride suitable for toothpaste additives, welding flux, metallurgy, or other industrial applications? Are there regulatory considerations?

Yes – W&Q's Sodium Fluoride (standard ≥98%, other purity customizable) is optimized for welding flux, toothpaste additives, preservation, bactericide, metallurgical slagging, and use in adhesives, paper-making, and construction. For toothpaste and related uses, we offer compliant high-purity grades. We provide full SDS, safety guidelines, and documentation to support safe use and local regulatory compliance.
