Sodium Silicate Adhesives

SpecialChem / Feb 22, 2006

Commonly known as "water-glass", soluble sodium silicates are colorless low cost inorganic materials. When used as adhesives, liquid silicates offer significantly low cost, versatility, and ease of handling. Their main use is to bond porous substrates such as paper and cardboard where an inexpensive, fast processing adhesive is required. Other adhesive applications for sodium silicates include bonding of wood, metal foils or glass to porous substrates, glass fiber insulation bonding, as well as the fabrication of foundry molds and abrasive wheels. Because of its inorganic nature sodium silicates can be formulated into industrial cements with exceptionally high resistance to temperatures and chemicals. Sodium silicate adhesives are usually supplied as a viscous water solution. The adhesive bond forms by (1) the evaporation of water and / or (2) chemical reaction. Sodium silicate water solutions are often used directly as an unmodified adhesive, but they can also be blended with polymeric additives to improve specific properties such as toughness.

Dear Sir / Madam I went through your article regarding sodium silicate for adhesives, and tried on my home project. I tried to spray on my glass table top and left it for a few days to dry but there was no affect, i tried using a hair dryer the liquid started to foam. Then i tried to spray on my wood table and the same thing happened. I also tried doing it by paint brush but it did not dry. Can you please help me thanks Rommy.L Jakarta, Indonesia
