Potassium Silicate For Welding Rod

Potassium silicate is specifically recommended as a binder for consumable electrodes ([stick rods") which are used with alternating current welding machines. Along with good binding properties, potassium silicate serves as a fluxing component and produces a steady hot arc, with lower arc voltage than sodium silicate, which tends to sputter or extinguish. Higher tensile strength and less elongation of weld metal can be obtained. Potassium silicate finds use as a binder in welding rods for mild, low-hydrogen, and stainless steel. 865 grade, available in glass or solution form, represents an excellent balance of potassium for a uniform arc and silicate for binding and fluxing.
