Primerless to Glass Polyurethanes

Sikaflex® primerless to glass windshield polyurethanes are built to eliminate steps, increase robustness (reduce mistakes of workmenship) and speed up installation by providing primerless adhesion to glass. These products are based on OEM approved polyurethane technology and are compatible with Sika’s establised All Black and Black Primerless installations processes. Sikaflex® primerless to glass polyurethanes contain a built-in adhesion promoter and may be used as a primerless to glass adhesive in auto glass replacement applications.

With its primerless-to-glass polyurethane solutions, Sika is responding to evolving industry needs, including the growing focus on health and well-being in the workplace..

Exposure to solvent smell after the windshield installation can be an unpleasant experience and, in some cases, can have an effect on health as well. 

The latest generation of Sikaflex® primerless polyurethanes is solvent-free. Installations done with the Sikaflex® primerless adhesives do not leave an unpleasant odor in the car after replacing the windshield.

Removing the solvent from our primerless adhesives offers a pleasant application and an enjoyable experience for our customers when they pick up the vehicle again.
