SO VCI® Rustopowder and Suprabha Dehumidifier desiccant

Silica gel can hand moisture back to the pack when the day warms up, and turns acidic. Suprabha’s answer is two products: Rustopowder, whose VCI vapour coats every surface in the pack, and Suprabha Dehumidifier, a clay-based desiccant that holds on to the moisture it absorbs.

FAQ

Rustopowder & desiccant: questions buyers ask

How much Rustopowder do I need?

About 5 g per cubic foot of pack volume protects almost any metal surface for a full year. With Suprabha Dehumidifier, 2.5 g/cft is enough.

Why not just use silica gel?

Silica gel absorbs and stores moisture but can release it back when temperatures rise, and becomes acidic. Suprabha Dehumidifier is clay-based, near-neutral and does not release the moisture it absorbs.

How much moisture does Suprabha Dehumidifier absorb?

Up to 85% of its own weight. About 20 g per cubic foot controls humidity when used with Rustopowder.

What pouch sizes are available?

Rustopowder comes in 5, 10, 20, 50 and 100 g pouches, and in tablet form.

Is it safe for electrical parts?

SO VCI® does not impact the working of most electric and electronic components, which makes Rustopowder suitable even in working electric panels.
