ReViSalt receives seven-figure investment from TGFS

TGFS Technologiegründerfonds Sachsen is investing a seven-figure sum in ReViSalt GmbH, a Freiberg-based tech start-up specializing in the chemical strengthening of glass.

Leipzig - ReViSalt GmbH, a spin-off from the Institute of Glass and Glass Technology at TU Bergakademie Freiberg, is bringing industry-proven expertise in the mechanisms of glass tempering and strengthening to the market. With regeneration materials and a new process approach for chemical strengthening, they offer technologies that are already being tested by well-known players in the glass industry.

The team impresses with its excellent technical and sales expertise. Within a short space of time, they have succeeded in establishing solid contacts and references and laying the foundations for their own production.

Sören Schuster, Managing Director TGFS

Chemically strengthened glasses are more stable and resistant than normal glasses. They enable thinner and lighter products, have new applications and reduce costs and emissions. The difficulties and costs of the chemical strengthening process are mainly due to the long duration of the process and the complex mechanisms involved. The glass products are kept in a special bath of molten salt for several hours. However, this salt bath wears out after several runs and has to be replaced at great expense. Due to these challenges, the process has so far only been used for expensive products.

The regeneration of a salt bath saves resources, energy and costs - and not least maintains the quality of the glass refined in this way.

Dr.-Ing. Martin Groß, Co-Managing Director ReViSalt

ReViSalt has developed solutions to deal with the problems associated with the chemical strengthening process. They have developed special materials called SaltClean that make the salt bath last longer and reduce wear. As a result, the salt needs to be replaced less frequently and the service life of the salt bath can be extended. They also have a new process approach that accelerates solidification and greatly shortens the processing time. By combining these two technologies, a new level of chemical solidification is achieved.

With our technologies, chemical bonding will become economical for a wide range of applications. New products and markets will emerge

Michael Heidan, Co-Managing Director ReViSalt

The investment by TGFS Technologiegründerfonds Sachsen in ReViSalt GmbH, which was founded in 2021, is a seven-figure investment. These funds, together with additional debt capital, will be used to further develop the company and production.
