Sodium Silicate Solution

Sodium Silicate Solution

1. Basic Introduction

Sodium Silicate Solution, commonly referred to as water glass, is an essential water-soluble inorganic silicate liquid widely applied in modern industrial fields. It appears as colorless, transparent or slight grey viscous liquid with moderate alkalinity, outstanding adhesive force, excellent film-forming property and stable chemical performance. This product features great weather resistance, high-temperature resistance, corrosion resistance and flame retardant characteristics. As a cost-effective and eco-friendly basic chemical raw material, it has stable quality, easy dilution and convenient on-site operation, serving as a critical auxiliary material for multiple manufacturing and processing industries.
