Sodium silicate

ABOUT PRODUCT

Sodium silicate adhesives, derived from easily accessible and cost-effective raw materials, boast an economical edge over many synthetic organic polymer-based adhesives. Notably, their exceptional resistance to extreme temperatures sets them apart, with some variants capable of withstanding up to 1100°C. Their inherent inorganic composition renders them completely flame-resistant and impervious to microbial or animal degradation. As a consequence, sodium silicate adhesives find frequent application in the realm of building and construction.
Sodium silicate water solutions serve as versatile adhesives, either in their pure form or when combined with polymeric enhancers to enhance toughness. Additionally, they find utility as cost-effective modifiers in various water-based adhesives. While these adhesives exhibit a moderate level of tackiness, sustained pressure is necessary until the bond adequately sets. Fortunately, the rapid drying properties of sodium silicate solutions facilitate their usage in applications demanding swift machine operations.
Sodium silicate solutions are frequently employed as a standalone adhesive or combined with polymer additives to enhance desired characteristics such as durability. Additionally, they serve as cost-effective modifiers in various water-based adhesives. These formulations exhibit a moderate level of tackiness, necessitating consistent pressure application until the bond sets adequately. Thankfully, the rapid drying nature of sodium silicate solutions enables their utilization in applications demanding swift machine operations.
The main advantages of sodium silicate adhesives are:
  • Relatively low cost
  • Total resistance to combustion, and
  • Suitability for fast, waterborne coating application to many porous substrates
