Chematur is marketing a process to produce Sodium Percarbonate (SPC) which is based on mixing Sodium Carbonate and Hydrogen Peroxide in a fluid bed where heat is input to remove the water. The mixing device is proprietary and patented.

The SPC produced is withdrawn from the fluid bed as granules of a specific size. The SPC granules can be coated with an inert substance to improve the storage stability which is important, especially at warm, humid conditions.
