Potassium Silicate
Potassium silicate in powder and liquid (oil) grades — used in welding-electrode coatings and acid-resistant cements, manufactured and supplied by RK Rubber.
Potassium silicate is a high-purity inorganic binder used in welding-electrode coatings and specialty acid-resistant cements, offering strong binding performance where sodium silicate isn't the ideal fit.
We manufacture it in both powder and liquid (oil) grades to suit different mixing and application processes.
