Sika® Aktivator-110 LUM
Sika® Aktivator-110 LUM is a solvent-based colorless adhesion promoter, which reacts with moisture and deposits active groups on the substrate. These groups act as a link between substrates and primers or sealants/adhesives. Sika® Aktivator-110 LUM is specifically formulated for the treatment of bond faces for vehicle glass installations prior to application of Sika’s 1-component polyurethanes. Sika® Aktivator-110 LUM fluoresces under long-wave UV light for a limited period of time. This feature is used for in-process control.
- Visible under UV light, suitable for automated in-process control
- Easy to apply
- Suitable for different substrates

IMPORTANT NOTE
Sika® Aktivator-110 LUM contains solvent which may dull the surface finish of some freshly applied paints. Preliminary trials must be carried out. Never apply to porous substrates since it may not dry completely and prevent the adhesive or sealant from curing. Protect adjacent surfaces by masking where necessary. Sika® Aktivator-110 LUM is a moisture reactive system.
In order to maintain product quality it is important to reseal the container with the inner plastic liner immediately after use. Once the surface pre-treatment operation is completed the cap has to be screwed on. Prolonged exposure to atmospheric moisture will cause Sika® Aktivator-110 LUM to become inactive. Immediately discard Sika® Aktivator-110 LUM if it has become opaque instead of clear. Dispose of product one month after opening.
If used on transparent or translucent substrates such as float glass, plastics, etc., an adequate UV protection is mandatory.
Never dilute or mix Sika® Aktivator-110 LUM with any other substances.
It must not be used for tooling/smoothing of products or as cleaning agent.
DETECTION OF THE LUMINESCENCE
Sika® Aktivator-110 LUM can be visualized by using a light source with a wavelength of 320 to 420 nm as in-line control. By reducing foreign light such as sunlight or artificial light during the detecting process the quality of the detection can be increased significantly.
Note: The luminescent effect will degrade with time.
Application
METHOD OF APPLICATION
Surfaces must be clean, dry and free from grease, oil, dust and contaminants.
Adhesion on substrates may be improved by adding and/or combining pre-treatment processes such as scuffing and cleaning prior the activator application.
Application
Wipe bond faces with a clean, lint-free paper towel moistened (not wet) with Sika® Aktivator-110 LUM. Immediately wipe-off with a clean, dry, lint-free paper towel. Never dip the towel into the activator. Only wipe the surface with a clean side of the towel. Do not moisten the same paper towel twice and change it frequently.
Do not touch pre-treated bond face.
Sika® Aktivator-110 LUM has to be applied sparingly as excess of activator could lead to adhesion failure.
If the pre-treated area is not bonded within the maximum flash-off time, the activation process has to be repeated (once only).
Ideal application and surface temperature is between 15 °C and 25 °C.
Consumption and method of application depends on the specific nature of the substrates.
Tightly reseal container immediately after each use.
