Nov 12, 2015· So I need some sodium silicate and I happened across somebody making it from oven cleaner (sodium hydroxide) and silica gel. Has anybody ever tried this out before? Going to look into it a bit more but it seems a lot cheaper than buying it. Seems like an interesting material I dont know much about.
Water glass, also called sodium silicate or soluble glass, a compound containing sodium oxide (Na 2 O) and silica (silicon dioxide, SiO 2) that forms a glassy solid with the very useful property of being soluble in water.
Sodium silicate, also known as "liquid glass," as a versatile and widely used solution.Sodium silicate is known as liquid glass for good reason: When the water it is dissolved in evaporates away, the sodium silicate bonds into a solid sheet of glass.
In this application, the sodium silicate (60–70%) is typically mixed with kaolin (40-30%), an aluminium silicate mineral, to make the sodium silicate "glued" joint opaque. The sodium silicate, however, is the high-temperature adhesive; the kaolin serves simply as a compatible high-temperature coloring agent.
the use of sodium silicates for various water treat-ment applications in ANSI/AWWA Standard B404. Sodium silicates with NSF certification are also available from PQ. ... PQ sodium silicate finds use in these applications because of its natural adhesive properties and its ability to provide a quick set and cost savings. Agglomeration.
The advantages of sodium silicate adhesives include their ability to expand and make contact; a controllable index adjustment across broad ranges; and the formation of a rigid layer that is a strong, permanent seal resistant to tearing, bugs (i.e., pests) and moderately resistant to heat and water.
