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®-255 Ultra is capable to bond on glass and ceramic frits without additional pre-treatment. It is compatible with Sika's Black-Primerless or All Black installation process for best results.
Further information on the application and use of pre-treatments, can be found in the corresponding Product Data Sheet.
Note: Glass without ceramic coatings need proper UV protection.
Application
Sikaflex®-255 Ultra can be processed between 5 °C and 40 °C but changes in reactivity and application properties have to be considered. The optimum temperature for substrate and adhesive is between 15 °C and 25 °C.
Consider that the 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 recommend to apply the adhesive in form of a triangular bead (see figure 1).
