ReViSalt (formerly 2MH Glas) was founded in 2019 with the aim of industrialising an innovative process for the rapid chemical strengthening of glass developed by TU Bergakademie Freiberg. Glass in its untreated form is hard but fragile. The resulting restrictions in use limit its applications and, in most cases, attempts are made to achieve robustness with thicker walls. Chipping is also a quality defect and glass breakage often results in painful economic damage due to the loss of high-quality contents.
Conventional chemical strengthening is mostly used for high-quality products, such as displays made of aluminosilicate glass or expensive bulletproof glass and yacht glass made of soda-lime glass. This process lasts up to 24 hours and usually takes place in an immersion bath. With the new technology of rapid chemical strengthening offered by ReViSalt, almost all glass materials, including the inexpensive and widely used soda-lime glass, can now be chemically strengthened quickly for the first time. Chemically strengthened glass is now ready for mass production.
ReViSalt can quickly chemically strengthen flat and container glass with all its subcategories, such as display glazing, vehicle glazing, building glazing, food packaging, bottles and containers for the cosmetics, pharmaceutical and chemical sectors. Glass can now be thinner, lighter and still have greater strength.
Compared to the current state of the art, ReViSalt enables significant energy savings of up to 95% and up to 48 times higher production capacity. The tempering time is reduced to just 10 to 30 minutes instead of the previous 4 to 24 hours. In addition, cost-effective soda-lime glass can be used instead of expensive special glass.
At glasstec 2024, ReViSalt will be exhibiting a device (ball drop test – endless loop) that demonstrates how the chemically strengthened glass withstands a test.
