IGK 511 S

Butyl Primary Sealant for Foam Spacers

IGK 511 S is a single-component, thermoplastic, solvent-free, UV-stable sealant made from polyisobutylene, which was developed exclusively for the primary sealing of insulating glass panes with foam-based spacers.

IGK 511 S is characterised by its very high adhesive properties and impermeability and adheres outstandingly to glass and foam spacers.

The melting process is very rapid; application is even and its pressure grouting on foam spacers is outstanding.
