DRY TOP® Frequently Asked Questions

Q. What is Silica Gel?

A. Silica Gel is a dry solid, not a wet substance as the name might suggest. The capsules hold silica gel beads that remain dry to the touch even when fully saturated. The Silica Gel is made from sodium silicate, is a highly porous substance that can absorb up to 40% of its own weight, which makes this the highest absorption capacity of any commercially used desiccant.

Q. What is Indicating Silica Gel?

A. Our Cobalt Chloride (II) FREE indicating Silica Gel has been impregnated with a chemical that change from an orange color to a green color when it comes into contact with moisture. Silica Gel beads will turn from Orange to Dark Green when the Silica Gel is about 60% absorbed with moisture and it means that the Silica Gel is saturated and needs to be reactivated

Key Factor: There is a Blue Indicating Silica Gel that is impregnated with a color changing chemical containing Cobalt Chloride (II) that is blue when activated and pink when deactivated. There have been some significant health and environmental risks attributed to the use of Cobalt Chloride (II) within the Blue Indicating Silica Gel including possibly causing cancer, along with skin and respiratory irritation.

We offer a safer alternative which is Indicating Silica Gel that goes from orange to green and does not contain cobalt chloride which is classified as an IARC Group 2B carcinogen.
