Special potassium silicate used in welding electrode is one of main materials for the production of welding electrode. It plays the role of reducing agent and bonding agent for electric welding rods and electrodes. It also mainly used in resisting corrosion, reducing dyestuff industries, indispensable filler of soap,detergent and so on.
Potassium silicate is a colorless or with a bit green/blue, transparent, nontoxic and flavorless solid or thick liquid.
