Product Introduction

Potassium silicate used for welding rods is a colorless, slightly blue or slightly green, non-toxic, odorless, transparent, viscous liquid or solid.



Sodium potassium silicate with water glass is one of the main raw materials for producing welding rods, which plays a role in bonding and arc stabilization in the production of welding rods. It is also used as a raw material for fluorescent screen adhesives, precision casting adhesives, coatings, reducing dyes, and silicon compounds. It is a colorless, slightly blue or slightly green, transparent, non-toxic, odorless viscous liquid or solid.



Adhesive used for producing welding electrodes, available in various specifications according to customer needs.
