Silmaco Sodium Trisilicate

Sodium trisilicate is produced in a state-of-the art granulation plant allowing a careful control of the composition (ratio, hydration, particle size) which ensures a stable product quality ! It is hydrated for a quicker dissolution in water. Sodium trisilicate is a versatile product that shows effective corrosion inhibition, good bleach stabilizing- and binding properties. The product is made from sand and soda ash and recognized as environmentally safe. Our sodium trisilicate is particularly suitable for use in dry-mix products and where less water is desired.

Product Highlights

Our hydrated sodium trisilicate contains both silica and alkalinity in a molar ratio of 3,4:1 between silica and sodium oxide. In addition, as it is hydrated it contains 17% of water which improves it's solubility. Our powder range has been specifically developed to meet the demand for different rates of solution and reactivity. Sodium trisilicate granular is a white free-flowing product with a SiO2/Na2O molar ratio of approximately 3,40 and a solid content of 83%.

Advantages
  • White and free-flowing granules and powders
  • High bulk density
  • Good bleach stabilizing properties
  • Effective corrosion inhibition
  • Outstanding binding properties to metals, ceramics, glasses and fibers
  • High temperature resistance (up to 1600°C)
  • Non-toxic and non-flammable

Safety & Health

Safety and Handling

Sodium trisilicates are alkaline products which are classified as irritating. They should be handled with care in order to prevent injuries. Whenever sodium trisilicate as a substance on its own or in a preparation is handled outside closed systems, suitable personal protective equipment (gloves, goggles, dust masks or respirators) is the preferred and only measure of control. We strongly advise to carefully read our corresponding Material Safety Datasheet before using the product.
