IGK 311

Polysulfide Edge Sealant

IGK 311 is a solvent-free two-component sealant and adhesive made with polysulfide, which was developed especially as a secondary sealant and to connect multi-pane insulating glass.

IGK 311 is characterised by its above-average adhesion and very good water vapour- and gas retention rates.

The product can be processed using all conventional two-component mixing and dosing machines and two-component manual systems. IGK 311 adheres to all conventional clean, dry, grease-free and oil-free base coats used in the insulating glass industry.
