Self-bonding Solvent-based
Self-bonding Water-based (water dilutable self-bonding varnish)

This varnish is used in a special compound technology where the coated laminations of the core stack are not fixed by mechanical or welding connections, but are bonded only by pressure and temperature. This special bonding technology consists of 2 steps: first, the electrical steel is coated with Voltatex® 1175/1175W and dried (but not cured) in a tunnel oven, whereby the curing reactivity remains preserved. In a second step, the bonding of the punched parts is carried out under pressure and temperature, leading to the complete curing of the self-bonding varnish. A more elastic bonding over the whole surface resulting in reduced noise is a main advantage of this special compound technology. The use of special catalysts limits the squeezing of the varnish at the edges of the lamination.
