Additional treatments for electrical steels

Additional treatments by voestalpine not only offer added value in the areas of corrosion protection or forming aids, but also for highly efficient electrical steel stacks. In close cooperation with leading European varnish producers, voestalpine supplies insulating varnishes that meet specific customer requirements. The varnishes do not contain any toxic, carcinogenic or mutagenic substances.

Backlack Standard

The Backlack Standard is characterized by a number of efficiency and processing advantages when compared to conventional joining techniques. 


Upgrade your Backlack! With its development of the innovative backlack-v® coating voestalpine has made it possible for customers for the first time to efficiently bond electrical steel packages for applications in generators and industrial engines while improving product quality at the same time. 

Backlack-v + Accelerator

backlack-v® + Accelerator is a high-speed bonding varnish system for electric motors of all sizes and types, even in large-scale production. The backlack-v® varnish features a significantly reduced bonding temperature, and the combination of backlack-v® with a reaction accelerator reduces bonding times to a minimum.
