The curing of SikaForce®-110 CT55 takes place by chemical reaction between the adhesive and moisture. Higher temperatures speed up the curing process and lower slow it down.
In case of chemical or thermal exposure, conduct project related testing.
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.
Typically a coat weight between 100 and 300 g/m2 is applied, depending on the substrates to be bonded. The specific coat weight for a given substrate combination must be determined by tests.
SikaForce®-110 CT55 is a moisture curing adhesive. A water mist of approx. 10 % of the adhesive coat weight, sprayed either on the adhesive or the bond face, is required.
To prevent curing of the product in the short term, the dosage nozzles for 1-component polyurethane adhesive are typically submerged in a tray filled with SikaForce®-097 Nozzle Oil, when not in use.
For manual application, apply with trowel, spray water mist on the surface and press parts together before the end of the open time.
For support on selecting and setting up a suitable pump system, contact System Engineering Department of Sika Industry.
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.
Uncured SikaForce®-110 CT55 may be removed from tools and equipment with SikaForce®-096 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.
SikaForce®-110 CT55 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.
