Sodium Silicate Solid Powder

Milled solid sodium silicate for formulators who need a dry, high-solids silicate with slower, controlled dissolution.

Sodium Silicate Solid Powder
Product Overview

Ground solid silicate for controlled release.

Sodium silicate solid powder is produced by milling solid silicate to a defined particle size, giving a high-solids dry material that dissolves more gradually than spray-dried powder. That slower profile is useful wherever silicate must become available over time rather than instantly.

It suits dry blends and site-mixed systems in which the silicate acts progressively — refractory and construction mixes, slow-release cleaning blocks and certain foundry preparations.

Properties & Advantages
01

High active content

Minimal bound water, so more silicate per kilogram.

02

Controlled dissolution

Particle size selected to tune the release rate.

03

Blend stability

Low reactivity in dry storage alongside other ingredients.

04

Cost efficient

Solid form avoids the freight and handling cost of solution.
