Grinding discs for edge deletion
Edge deletion is a central topic for gas-tight, coated IG units. As a rule, butyl is used as the primary seal. However butyl only establishes an inadequate connection with the coated IG unit! Therefore it is strictly necessary to remove the coating in the edge area.
To do this either automatic edge deletion systems or manual grinding devices are used. Both systems use a grinding disc for edge deletion. A different composition of the abrasive material, as well as grit and degree of hardness, are necessary depending on the coating and the machines used. Usually uneven edge deletions cannot be detected visually. However the consequences are serious: leaks.
