Sika® Aktivator-100 is a solvent-based colourless 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-100 is specifically formulated for the treatment of bond faces prior to application of Sika’s elastic adhesives and sealants.

Usage

Sika® Aktivator-100 is used to improve adhesion on substrates such as float glass, ceramic screen prints, the cut face of old Polyurethane adhesives and paints. After intensive testing, this activator is also suitable to enhance the adhesion of other Sika sealants and adhesives on non-porous substrates. Seek manufacturer’s advice and perform tests on original substrates before using Sika® Aktivator-100 on materials prone to stress cracking. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.

IMPORTANT NOTE

Sika® Aktivator-100 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-100 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-100 to become inactive. Immediately discard Sika® Aktivator-100 if it has become opaque instead of clear. Dispose of product approx. one month after opening if used frequently or after two months in case of infrequent use. 30 ml cans and pads are for single application only.

Never dilute or mix Sika® Aktivator-100 with any other substances.

It must not be used for tooling/smoothing of products or as cleaning agent.

If used on transparent or translucent substrates such as float glass, plastics, etc., an adequate UV protection is mandatory except for Sikasil® silicone sealants and adhesives.

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-100. 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.

Sika® Aktivator-100 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.
