Silica Gel Blue Description

Blue semi-transparent glassy substance containing an indicator as “cobalt”. When free from moisture the Granules or beads are dark blue in color. As the beads takes up moisture, they turns to light blue gradually & When they turn pink, it indicates that the gel need to be replaced or regenerated. In fact, it is mainly used as indicator for the extent of dehumidification and moisture absorption in sealed vessel
