Sika® Primer-507

Pigmented, Purform® based primer for various substrates

Sika® Primer-507 is based on Purform®, a polyurethane with less than 0.1 % monomeric diisocyanate for better health protection and occupational safety. It 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-507 is specifically formulated for the treatment of bond faces prior to application of Sika’s elastic adhesives and sealants. This primer might provide excellent adhesion without previous activation step on many substrates. Sika® Primer-507 fluoresces under long-wave UV light for a limited period of time. This feature is used for in-process control.  

  • Suitable for many substrates

PRODUCT BENEFITS

  • Suitable for many substrates
  • Less than 0.1 % monomeric diisocyanate for better health protection and occupational safety
  • Visible under UV light
 

Areas of Application

Sika® Primer-507 is used to improve adhesion on a very broad range of different substrates such as float glass, ceramic-coated glass, plastics, pre-coatings, painted surfaces, E-coats and metals.
Seek manufacturer’s advice and perform tests on original substrates before using Sika® Primer-507 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.

Technical Information

IMPORTANT NOTE

If Sika® Primer-507 is used below 5 °C further testing under expected conditions are mandatory.
Sika® Primer-507 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 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. Packages smaller than 100 ml are for single use 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-507 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, cleaning and activating.

Application

Shake the Sika® Primer-507 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 are between 15 °C and 25 °C.
Sika® Primer-507 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.
