Product Description and applications:

Stannic Chloride Anhydrous is a clear, colorless, heavy fuming liquid. It fumes in moist air to form basic chloride, solid and semisolid hydrates, and liberates vapors of Hydrogen Chloride. It is miscible with most hydrocarbons and chlorinated hydrocarbons. Mason's Stannic Chloride is of the highest purity found in the world with no free chlorine present in the final product.

One of the largest applications for Stannic Chloride is its ability to toughen glass. As hot glass is released from the mold into a spray or vapor of Stannic Chloride, a thin film of tin oxide is deposited on the surface of the glass. The film imparts a scratch and scuff resistance to glassware such as bottles and jars used for food and beverages. Stannic Chloride can also provide electroconductive coatings for solar collectors. A thin tin oxide coating on glass panels used in solar collectors provides an electroconductive path for the energy collected by the panels. Stannic Chloride is used to stabilize PVC plastics against heat. Unstabilized PVC can be degraded by heat and other forms of radiation. Stannic Chloride acts as an intermediate in the formation of organotin compounds such as thiotin, one of the most efficient heat stabilizers available. It also imparts exceptional clarity to the product which can be used for blow-molded soft drink and cooking oil bottles and other applications where high transparency is desirable.

Stannic Chloride serves as a chemical intermediate in the manufacture of:

  • Pharmaceuticals
  • Polymers
  • Resins
  • Urethane
  • Pesticides
  • Paint
  • Fungicides
  • Wood preservatives
  • Electroconductive coatings
  • Security alarm glazing
  • De-icing of windshields

If the presence of water is required, a Stannic Chloride Solution may be preferred.
