Non sagging assembly adhesive

SikaForce-422 L105 is a high viscous 2-component polyurethane adhesive for assembling sandwich panels and similar constructions of various materials.  

  • Non sagging
  • Good gap filling properties
  • Solvent free
  • Long open time
PRODUCT BENEFITS
  • Non sagging
  • Good gap filling properties
  • Solvent free
  • Long open time
 
Usage
SikaForce-422 L105 is used primarily for assembling of profiles and sandwich constructions of e.g. glass fibre reinforced plastic, wood, metal, ceramic materials and pre-treated plastic materials. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed, ensuring adhesion and material compatibility.

Technical Information
CURE MECHANISM

The curing of SikaForce-422 L105 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.
Application

Volume and positioning of the adhesive must be defined in a way, that the intended gap is sufficiently filled after joining the parts. The specific applied quantity and position must be determined by tests.
The procedure for manual application is as follows: Ensure that the A-component is stirred thoroughly to avoid any sediment or separation, taking care not to stir too vigorously as this may introduce air into the product. Add the B-component in the specified ratio and stir thoroughly, ensuring a homogeneous mixture is achieved.

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.
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-422 L105 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-422 L105 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.
Lowest temperature during transportation is  -20 °C for max. 7 days.
