- Quick, clean and easy to apply
- Short flash off time
- Single wipe process
Areas of Application
Sika® Aktivator PRO has been especially designed for the Automotive Glass Replacement business. It can be processed down to −10 °C without special requirements. The broad application temperature range in combination with the short flash off time makes it an all year round product, which is ideal for mobile or in-house applications. This product is suitable for experienced professional users only. For other applications than glass replacement, tests with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.Product Details

IMPORTANT NOTE
Sika® Aktivator PRO 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 PRO to become inactive. Dispose of product approx. one month after opening. Sika® Aktivator PRO pads are for single application only.
Never dilute or mix Sika® Aktivator PRO with any other substances.
It must not be used for tooling/smoothing of products or as cleaning agent.
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
Apply Sika® Aktivator PRO sparingly without wipe-off process.
Ideal application and surface temperature is between -10 and 45°C. Prolonged exposure to atmospheric moisture will cause Sika® Aktivator PRO to become inactive.
Can
Moisten a clean and lint free cloth or paper towel with Sika® Aktivator PRO and wipe bonding surfaces once ensuring the bond face has been treated.
Consumption and method of application depends on the specific nature of the substrates.
Tightly reseal container immediately after each use.
Pad
Hold pad directly against the frit on the glass, then pinch the handle with thumb and index finger to break internal vials thus releasing Sika® Aktivator PRO into the pad (do not bend!).

Apply the Sika® Aktivator PRO to the glass in one direction while maintaining continuous contact. Finish just beyond the beginning point to ensure complete coverage of bond area.
FAQ
- Sika® Aktivator PRO and Sika® Primer-207 contain reactive components which react chemically with glass, paint and other materials. Once cured, they can only be removed mechanically and the upper layer of the substrate is damaged in the process. Care must be taken to apply Sika® Aktivator PRO only to the required areas. If the product is applied to the transparent area of the glass, it will be visible and the customer will have cause for complaint.
- Sika® Aktivator PRO performs a cleaning function, as well as an activating function. Application with a dauber simply moves dirt around and does not clean it off. Daubers apply too much product, which is unnecessary and wasteful.
- They can become dirty and contaminate the activator if they are dipped in the bottle several times.
- Yes. It is OK to apply Sika® Aktivator PRO up to three times onto the bonding surface. It is important that the surface is clean and activated. You can tell if the surface has been activated when it has a shimmery aspect to it. If you are uncertain it is better to re-apply Sika® Aktivator PRO.
- Yes, Sika® Aktivator PRO can be used in damp conditions, e.g. on windshields with a light misting of condensation. (In this application, ‘damp’ refers to any humid condition where larger water droplets are NOT visible, either as pooled condensation or as spots of rain). However, it is better if the part is dried first.
