Technical Information CURE MECHANISM The curing of SikaForce-648 L10F 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 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.
During the curing process, carbon dioxide is released from the adhesive. If none of the substrates are porous, measures need to be taken to allow the carbon dioxide to escape. Application Typically a coat weight between 100 and 250 g/m2 is applied, depending on the substrates to be bonded. The coat weight for a given substrate combination must be determined by tests. For A2 classified panels, the maximum coat weight must be determined by calculation according to EN14509.
The product is only suited for use on continuous production lines.
For automated applications, contact the System Engineering Department of Sika Industry. Pressing An adequate bonding pressure is necessary to obtain a voidless contact between the substrates and the adhesive. The specific pressure is, however, dependent on the core material and must be determined by tests. The pressure must always be below the maximum compressive strength of the core. After starting the press process, do not release the pressure until the press time has elapsed. Removal Uncured SikaForce-648 L10F may be removed from tools and equipment with SikaForce-096 Cleaner (formerly SikaForce-7260 Cleaner). 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-648 L10F 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. |
