Preparation of the window.
9. Lay the polycarbonate window on a stable and flat surface.
The 8 mm polycarbonate window has a 20 mm milled area all around the window and black painted area to protect the bonding material against UV exposition. Be careful while removing the polyeurethane adhesive to not alter that black paint layer.
Use a cutout knife in order to remove the remaining adhesive from the polycarbonate perimetrical milled surface (20mm width).
Prepare the polycarbonate window by applying primer Sika? primer 209 to the milled area around the window. Refer to Image1.9.1 and 1.9.2.
Use a foam brush to evenly apply primer.
Allow the primer to dry at least 30 minutes and no more than 24 hours at 23?C (73?F). Do not apply at temperature below 10?C or above 35?C.
Care must be taken that this application gives adequately dense coverage.
Reseal the container tightly and immediately after use.

Image1.10.1
Dimensions for the width and the height of the adhesive are 10 - 15mm (0.39 to 0.59 inch) (width) and 10mm (0.39 inch) (depth). Refer to Image1.11.1.
Cutting a groove into the tip of the cartridge will help in the even application of the Sikaflex? 295 - UV. Refer to Image1.11.2.
