High performance non-sagging structural adhesive

SikaForce-818 L07 is a structural 2-component polyurethane adhesive, which cures at room temperature.It is designed for bonding composite components. The adhesive is characterised by fast curing and strength build-up. While uncured, it has very good non-sag and compressibility behaviour.  

  • Very good non-sag behaviour
  • Short curing time
  • High strength and modulus for structural bonding applications
  • Low smell
  • Does not contain solvents or PVC
PRODUCT BENEFITS

Technical Information
CURE MECHANISM

The curing of SikaForce-818 L07 takes place by a chemical reaction of the two components. Higher temperatures speed up and lower temperatures slow down the curing process. The final glass transition temperature, as well as the tensile and shear strengths, may be increased with higher curing temperature.

CHEMICAL RESISTANCE

In case of chemical or thermal exposure, it is required to conduct project related testing.
Application Information
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 dispenser.
To ensure good mixing quality the defined static mixer is to be used.

Extrude adhesive without mixer to equalise the filling levels. Attach the mixer and dispose the first few cm of the bead before the application.

SikaForce-818 L07 can also be processed from pails with adequate 2-component equipment. For automated applications, contact the System Engineering Department of Sika Industry.
Removal

Uncured SikaForce-818 L07 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-818 L07 has to be kept between 10 °C and 30 °C in a dry place. Do not expose it to direct sunlight or frost. After opening of the packaging, the content has to be protected against humidity.
The lowest allowed temperature during transportation is -20 °C for max. 7 days.
