| Introduction: |
Sodium Silicon Flouride is mainly used in glass and enamel creamilizer, fusing agent, pesicider, ,hygroscopic agent and solidificater for acid resisting binder cement, stuff material of certain plastic, and the freeze-thaw of mercury, etc.. It can also be used in corrosion protection, pharmaceutical, leather, and rubber industry as well as the fluorating of drinking water. All our productions are according to the National Bureau, so to ensure the stable quality, with an assay above 98.5%. We have smoothly passed the ISO9002 quality standard system accreditation in 1999. |
