Applications
● Construction
● Fertilizer
● Pesticide
● Extinguishant
● Pellet binder
● Insulating material, waterproof material, paint, coating, printing industry, etc.
Features
● Improve compressive strength, bond strength, abrasion resisitance, reduce permeability in construction application.
● As dispersant for chemical products, micro silica instead of mica or diatomite to prevent fertilizer particles caking. Making potassium silicon compound fertilizer, protect the soil from erosion or deterioration.
● With strong adsorbability and large specific surface, as anti-caking agent or pellet binding agent improve economic performance.
