Sika® Primer-206 G+P

Sika® Primer-206 G+P

Pigmented, solvent based primer for various substrates

Sika® Primer-206 G+P is a solvent-based black primer, which reacts with moisture and forms a thin layer. This layer acts as a link between substrates and adhesives. Sika® Primer-206 G+P is specifically formulated for the treatment of bond faces prior to application of Sika’s 1-component Polyurethanes.  Sika® Primer-206 G+P fluoresces under long-wave UV light for a limited period of time. This feature is used for in-process control.

Technical Information

IMPORTANT NOTE

If Sika® Primer-206 G+P is used below 5 °C further testing under expecting conditions are mandatory.
Sika® Primer-206 G+P 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.

 

Dispose of product approx. one month after opening if used frequently or after two months in case of infrequent use. For 100 ml pack sizes dispose it of two weeks after opening. 30 ml cans are for single application only.

If gelling, separation or a significant increase in viscosity is noted, discard the primer immediately.
Never dilute or mix this product with any other substances.
If used on transparent or translucent substrates such as float glass, plastics, etc., an adequate UV protection is mandatory.

DETECTION OF THE LUMINESCENCE

Sika® Primer-206 G+P can be visualized by using a light source with a wavelength of 320 to 420 nm as inline 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

Application Information

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.
Pre-treat the bond face of the substrates with Sika® Aktivator-100 using the wipe-on, wipe-off method and allow flashing-off.

Primer Application

Shake the Sika® Primer-206 G+P can very thoroughly until mixing balls rattle freely. Continue shaking for another minute and apply a thin but covering coat with a brush, felt or foam applicator.
Ideal application and surface temperature is between 15 °C and 25 °C.
Sika® Primer-206 G+P has to be applied once only. Care must be taken to ensure that this single application gives adequately dense coverage. Consumption and method of application depend on the specific nature of the substrates. Tightly reseal container immediately after each use.
