Butylver glue

Primary Sealant Butyl

Butyl is a single-component, thermoplastic, solvent-free, UV-stable sealant made from polyisobutylene, specifically developed for primary sealing of insulating glass units.

Butyl is characterized by its very high adhesion and impermeability. It adheres excellently to glass, aluminum, stainless steel, and galvanized steel.

Butyl impresses with its very fast melting capabilities, high yield, and consistent application volume across a very wide temperature range.
