SikaForce®-800 Blue
Fast curing profile and surface filler for blade repair applications
SikaForce®-800 Blue is a two component polyurethane based profile and surface filler that works best at temperature below 15 °C. If ambient temperatures are higher than 15 °C it is advisable to use SikaForce®-800 RED.
- Superior mixing, application and tooling properties
- Very good adhesion to GFRP
- Non-sag up to layer thicknesses of approx. 20 mm
- Fast sanding time
- Easy to sand, does not clog the sandpaper

CURE MECHANISM
The curing of SikaForce®-800 Blue takes place by a chemical reaction of the two components. Higher temperatures speed up the curing process and lower slow it down.
CHEMICAL RESISTANCE
In case of chemical or thermal exposure, conduct project related testing.
Application
Surface preparation
Surfaces must be clean, dry and free from grease, oil, dust and contaminants. After the cleaning process, a physical or chemical pre-treatment might be required, depending on surface and type of material. The type of pre-treatment must be determined by tests.
Application
For the cartridge application use a suitable manual or a compressed air piston-type cartridge gun. To ensure good mixing quality the defined static mixer have to be used.
Extrude adhesive without mixer to equalize the filling levels. Attach the mixer and dispose the first few cm of the bead before the application.
Removal
Uncured SikaForce®-800 Blue may be removed from tools and equipment with Sika® Remover-208. 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.
Do not use solvents on skin.
STORAGE CONDITIONS
SikaForce®-800 Blue has to be kept between 10 °C and 30 °C in a dry place. Do not expose it to direct sunlight or frost.
The lowest allowed temperature during storage is -20 °C for max. 7 days.
