## Overview

Chemiphase Liquid Sodium Silicate 40% is a high-performance, water-resistant adhesive and sealer designed for automotive, industrial, and construction use. It forms a durable, heat-resistant glass-like bond that seals leaks and repairs metal, concrete, and glass surfaces, withstanding temperatures up to 815°C. Ideal for quick, long-lasting fixes such as radiator leaks and exhaust system repairs, this 5-litre liquid glass solution delivers professional-grade strength and versatility.

## Description

Sodium silicate is used, along with magnesium silicate in muffler repair and fitting paste. When dissolved in water, both sodium silicate, and magnesium silicate form a thick paste that is easy to apply. When the exhaust system of an internal combustion engine heats up to its operating temperature, the heat drives out all of the excess water from the paste. The silicate compounds that are left over have glass-like properties, making a somewhat permanent, brittle repair. Sodium silicate can be used to seal leaks at the head gasket. Rather than pull the head, a jar of "liquid glass" is poured into the radiator and allowed to circulate. The Waterglass is injected via the radiator water into the hotspot at the motor. This technique works because at 93 C the sodium silicate loses water molecules to form a very powerful sealant that will not re-melt below 815 C. This approach is often used by disreputable used-car salespersons to disguise a leaking head gasket. A sodium silicate repair of a leaking head gasket can hold for up to two years and even longer in some cases. The effect will be almost instant, and steam from the radiator water will stop coming out the exhaust within minutes of application. This repair only works with water to cylinder or water to Air applications and where the sodium silicate reaches the "conversion" temperature of 93 C. Sodium silicate is also used currently as an exhaust system joint and crack sealer for repairing mufflers, resonators, tailpipes and other exhaust components, with and without fiberglass reinforcing tapes. In this application, the sodium silicate (60-70%) is typically mixed with Kaolin (40-30%), an aluminium silicate mineral, in order 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.

## Questions & Answers

**Q: Can this be used to produce clay slip**
A: Yes, widely used

**Q: Can this be used to seal the inside of concrete candle vessels?**
A: Sodium silicate, when correctly applied to concrete dramatically reduces the porosity. I don’t know what a concrete candle vessel is but going back to basics, if reduced porosity and ultimately sealing the concrete is the required property then it can be achieved with sodium silicate. It was used in concrete fuel tanks in WW2 and also to manufacture disposable aircraft fuel tanks from silicate coated cardboard drums

**Q: what material is the container made of?**
A: The container is plastic...

**Q: Is this sodium silicate the same as used when working with pottery clay makingclay**
A: Yes this is used to reduce the viscosity of the slip without reducing the overall solids content
