Indicating – Silica Gel

Description

Indicating Silica Gel is made by processing sodium silicate to create a porous form of silicon dioxide (SiO2). Silica Gel can appear as beads or in granular form, tough and hard, and resembles glass. This product is a desiccant and is typically used in static applications to dry and maintain the humidity of a contained area. Using Silica Gel with indicating abilities allows the user to know when the product has reached its adsorption capacity.


Product Application

Blue Silica Gel can be utilized to maintain the integrity and quality of leather, shoes, clothes, foodstuffs, electronics, & medicine. With cobalt chloride, Blue Silica Gel turns from blue to pink after adsorbing moisture, visually indicating adsorption capacity has been reached and the product needs to be regenerated.

Yellow Silica Gel has been enhanced with phenolphthalein to allow for color indication. Yellow Silica Gel is sometimes
used in place of blue and is considered very safe for use around food or medicine.
