Butyl Primary Sealant

IGK 511 is a single-component, thermoplastic, solvent-free, UV-stable sealant made from polyisobutylene, which has especially been developed for the primary sealing of insulating glass panes.

IGK 511 is characterized by its very high level of adhesion and impermeability. It adheres outstandingly to glass, aluminium, stainless steel and galvanized steel.

IGK 511 impresses with its very rapid melting, high output  yield and a constant application volume over a very wide temperature range.
