SikaForce®-710 L30
Fast curing 2-component balancing material
SikaForce®-710 L30 is a 2-component polyurethane adhesive which cures at room temperature. It is designed for balancing of wind turbine blades. The system is characterized by high injectability and thixotropic viscosity build up.
- Room temperature curing
- High injectability
- Medium viscosity
- Easy to apply
- Solvent free
PRODUCT BENEFITS
- Room temperature curing
- High injectability
- Medium viscosity
- Easy to apply
- Solvent free
Areas of Application
SikaForce®-710 L30 is primarily used for balancing of wind turbine blades in factory but also for onsite-rebalancing. The material can be used in other industry applications such as bonding of sandwich panels after a detailed project review. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.Packaging

CURE MECHANISM
The curing of SikaForce®-710 L30 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
Apply before reaching half of the pot-life and join parts together within the open time. Consider that, if mixed in larger amounts, the exothermic reaction can reduce the pot-life and open time significantly.
SikaForce®-710 L30 can be applied with automated application equipments. For automated applications, contact the System Engineering Department of Sika Industry.
Removal
Uncured SikaForce®-710 L30 may be removed from tools and equipment with 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®-710 L30 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.
