Sodium Silicate Quick Dissolving

Updated: 2026-09-19

Overview

Sodium Silicate Quick Dissolving is a versatile industrial chemical known for its rapid solubility in water and strong binding properties. It is commonly referred to as water glass due to its glass-like appearance when solidified. The compound is produced by fusing sodium carbonate with silica sand at high temperatures, resulting in a product that dissolves quickly upon contact with water. This chemical is widely used across multiple industries, including construction, ceramics, and metallurgy, due to its adhesive and sealing capabilities. Its quick-dissolving nature makes it particularly valuable in applications requiring fast setting times, such as in foundry molds and detergents.

Physical and Chemical Properties

Sodium Silicate Quick Dissolving appears as a white or grayish powder with a density of approximately 2.4 g/cm³. It has a high melting point of 1088°C, making it stable under most industrial conditions. The compound is highly soluble in water, forming an alkaline solution with a pH typically ranging from 11 to 12.5. One of its key properties is its rapid dissolution rate, which distinguishes it from standard sodium silicate. This feature is critical for applications where immediate reactivity is required. Additionally, it exhibits strong binding and adhesive properties, making it ideal for use in cements, coatings, and sealants.

Main Applications

The primary use of Sodium Silicate Quick Dissolving is in the manufacturing of adhesives and binders, particularly in the construction industry. It is a key component in cement formulations, providing enhanced strength and durability. The compound is also used in detergents and soaps, where it acts as a buffering agent and helps in removing grease and stains. In water treatment, it serves as a corrosion inhibitor and a coagulant aid. Other applications include its use in ceramics for glazing, in metallurgy for mold casting, and in fireproofing materials. Its versatility and effectiveness make it a staple in industrial processes.

Safety and Storage

Sodium Silicate Quick Dissolving is alkaline and can cause skin and eye irritation upon contact. Proper safety measures, including gloves, goggles, and protective clothing, should be used when handling the chemical. Inhalation of dust should be avoided to prevent respiratory irritation. Storage conditions are critical to maintain the product's quality. It should be kept in a cool, dry place, away from moisture and incompatible substances such as acids. Properly sealed containers are recommended to prevent caking and degradation over time.

B2B Procurement Guide

When procuring Sodium Silicate Quick Dissolving, buyers should prioritize purity levels, typically 99% for industrial applications. Packaging options include 25kg bags or bulk shipments, depending on the scale of use. Supplier certifications, such as ISO or REACH compliance, are essential to ensure product quality and safety. Price ranges vary based on purity, quantity, and market conditions, with an approximate range of $300-$600 per ton. Buyers are advised to request samples and conduct quality tests before large-scale purchases. Additionally, logistical considerations, such as storage and transportation, should be factored into procurement decisions.
