Sodium Silicate Powder

Spray-dried sodium silicate in free-flowing powder form, for dry-blended detergents, cleaning compounds and construction products.

Sodium Silicate Powder
Product Overview

Silicate chemistry without the water.

Sodium silicate powder is the dried form of silicate solution, supplied as a readily soluble free-flowing powder. It gives formulators the binding, buffering and alkalinity of liquid silicate in a dry material that can be blended, bagged and shipped without tanker logistics.

It is the natural choice for dry-mix products — powder detergents, tile and grout compounds, welding-electrode coatings and dry cleaning blends — where added water would compromise shelf life or set time.

Properties & Advantages
01

Free flowing

Dry-blends cleanly with builders, surfactants and fillers.

02

Rapid dissolution

Dissolves in water to reconstitute silicate solution.

03

Lower freight

No water to transport, so more active material per consignment.

04

Long shelf life

Stable in sealed packing under dry storage conditions.
