Question: who is the ideal customer for chemical tempering?
Answer: every glazier who looks at the future of special products. There is now a lot of literature available on chemical tempering and more knowledge on the process.
In 2017, RCN promised to promote chemical tempering as an important job in the production of safety glass. At that time, it was clear that chemical tempering had the peculiarities to offer higher breakage and impact resistance than other treatments, but the approach of the glaziers was prudent, as if this system was just for big companies.
The latest news in matters of glass are reporting a trend to find technical solutions to lighten some installations, and the focus turned on thin chemical tempered glass for its high flexibility. Glass thicknesses as 0.5 millimetre or 0.7millimetre can be tempered and used as stronger glass laminated in between others to have a strong and safe product granting the features required by the regulations.
Currently under the spotlight, chemical tempering is something many glaziers are considering, and it is suitable for several jobs. There’s no need for specialised personnel or for HST, or to change potassium salts frequently; just add some when the level is reduced.
Energy consumption is low, with pre-heating at 300 degrees Celsius and process into the bath at 450 degrees Celsius. Once the temperature is reached the machine uses just 15 percent of the total installed power. The role of the potassium salts is fundamental and the use of a product without impurities determines the quality of the temper. RCN’s potassium salts are 99 percent pure, guaranteed by certified analysis.
The future of glass lies in new perspectives, and RCN is ready to respond with the right systems.
