Primerless Auto Glass polyurethane adhesive
Sikaflex® SOLO is a solvent-free primerless to glass windshield adhesive offering three (3) hours Minimum Drive-Away Time (MDAT). It provides a long open time and ensures safe application even under warm conditions. Installations done with the Sikaflex® SOLO do not leave unpleasant odour in the car after replacing the windshield.
Note: Primerless to glass application requires the glass to be prepared using an Automotive grade glass cleaner such as Sika® Cleaner G+P. The bonding surfaces must be free of contamination and have proper UV protection.

Application
Surface Preparation
Surfaces must be clean, dry and free from grease, oil, dust and contaminants. The bond faces must be prepared with an Automotive grade glass cleaner such as Sika® Cleaner G+P. Sikaflex® SOLO is capable to bond on glass and ceramic frits without additional pre-treatment.
Further information on the application and use of cleaning agent, can be found in the corresponding Product Data Sheet. It is compatible with Sika's Black-Primerless or All Black installation process. Windshields without ceramic coatings need proper UV protection.
Application
It is recommended to apply the adhesive with a piston-type application gun. Sikaflex® SOLO can be applied with good quality manual application guns. Consider that viscosity will increase at low temperature. For easy application, condition the adhesive at ambient temperature prior to use.
To ensure a uniform thickness of the bondline, it is recommended to apply the adhesive in form of a triangular bead (see figure 1).

The open time is significantly shorter in hot and humid climate. The glass must always be installed within the open time. Never install a glass after the adhesive has built a skin.
Removal
Uncured Sikaflex® SOLO may be removed from tools and equipment with Sika® Remover-208 or another suitable solvent. Once cured, the material can only be removed mechanically. Hands and exposed skin have to be washed immediately using hand wipes such as Sika® Cleaner-350H or a suitable industrial hand cleaner and water.
