2020 China New Design Weld Metal Powder - Potassium silicate for welding electrode production – Tianqiao

As the binder of welding powder for making welding electrode, potassium silicate is a colorless or slightly yellowish translucent to transparent glassy liquid substance, which is hygroscopic and has strong alkaline reaction. It decomposes in acid to precipitate silica. Potassium silicate is commonly used in the manufacture of welding rods, electrodes for welding, vat dyes, and fire retardants. In the stable state, it is a non-toxic, odorless, transparent, viscous liquid. Soluble in water and acid, insoluble in alcohol.
