Water Glass Works as an Excellent Adhesive

2 years ago 67 Views 1 comment

You couldn’t be more mistaken if you thought water glass – aka sodium silicate – can be used only for sand mold casting or metal mold making. While you may have heard that sodium silicate is often used to create an antique patina on ceramics, not many people know that it works as an excellent high temperature adhesive as well.

Indeed, the binding properties of sodium silicate make it an effective adhesive for bonding and coating applications. All you have to do is apply a thin layer of water glass on the surface or between two materials and let it dry. The liquid will react under acidic conditions and form a hard glassy gel after drying. This functions as a tightly adhering bond that is rigid, resilient, odorless, non-toxic, moisture resistant, non-flammable and resistant to high temperatures. It is also one of the most low-cost adhesives available!

Sodium silicate can be effectively used to bond different materials like metals, concrete, plaster, paper, glass, fiberglass, ceramics, and even refractory materials. Besides this, it works as an effective sealer for plaster and cement, and makes the surfaces where it is applied water repellant as well. It is a cheap and effective sealer for all types of concrete surfaces making them impervious to water and other liquids; think garage, shed and basement floors.

If you are wondering where to source this high temperature adhesive, just turn to EnvironMolds. This leading manufacturer and supplier of all kinds of mold making and casting products and equipment also offers liquid sodium silicate for varied applications like ceramics, metal mold making, concrete and plaster sealing, and adhesives.

Could this product be used to stiffen fabric maybe? I'm looking for a product that will stiffen fabric and remain it's shape in high heat and humid weather.
