IGK 611 XL

Reactive Thermoplastic Spacer

IGK 611 XL is a single-component, thermoplastic, solvent-free spacer made from polyisobutylene, which was developed especially for use in (reactive) TPS® systems. IGK 611 XL is characterized by its outstanding flow and chemical bonding to the glass surface with leads to an excellent adhesion to glass, when applied hot and with the subsequent grouting of the cold pane. The excellent adhesion between IGK 611 XL and the polyurethane secondary sealant IGK 130 means the edge seal is also mechanically stiffened in the insulated glazing unit. 

The product can be pumped very well and has a high level of stability up to a height of 20 millimetres. In addition, IGK is the only manufacturer whose reactive Thermoplastic Spacer® can be combined with both polysulfide and polyurethane – an economic alternative that has been proven for many years.
