Applications  

It is used commercial for insulating glass sealant strips and solvents 

Available in powder for dehydration of coating and polyurethane glue etc

Available in powder for dehydration of coating and solvents

Available in powder for dehydration in coating industry and paint industry 

Activated Alumina is non-toxic, insoluble in water and alcohol, high mechanical strength & strong adsorption of moisture.

Activated Alumina (sphere) A-AS-04

White sphere, odorless, tasteless, non-toxic, insoluble in water and alcohol, regular in particle size, smooth at surface, with high mechanical strength and strong adsorption of moisture, not expanding and cracking after adsorbing water, original shape kept.

As an effective concentrated drier for trace moisture, its drying capability could reach to dew-point below 70 under certain operating and recovering conditions. Widely used for drying in electronic, textile and oxidizing industry, also as adsorbent in air-grading industry (dew-point below 55). Its especially suitable for atmospheric temperature recovering equipment. Also could be used as a de-fluorinating agent of drinking water, a de-fluorinating agent of cyclical alkane in alkyl benzenes production, a de-acidifying regenerator of transformer oil, and as a dryer, purifying agent, catalyst and carrier in chemical fertilizer, petrochemical industries.
