Sika Primer-207 Adhesion primer 3N black 250 ml

Sika® Primer-207 is a black, moisture curing liquid primer specifically formulated for the treatment of bond faces prior to application of Sika® polyurethane adhesives and sealants. This primer may provide excellent adhesion without previous activation step on many substrates.
Sika® Primer-207 combines reduced flash-off time and fast adhesion built-up.
Sika® Primer-207 fluoresces under long-wave UV light.

Areas of Application:
Sika® Primer-207 is used to give improved adhesion in adhesive bonding applications on a very broad range of different substrates such as float glass, ceramic-coated glass, plastics, pre-coatings, painted surfaces, E-coats and metals.
This product is suitable for experienced professional users only.
Tests with actual substrates and conditions, especially boundary temperature conditions have to be performed to ensure adhesion and material compatibility.

Method of Application:
Surfaces must be clean, dry and free from grease, oil and dust.
Adhesion on substrates may be improved by adding and combining pre-treatment processes such as scuffing, cleaning and activating.

Application:
Shake the can of Sika® Primer-207 very thoroughly until mixing ball rattles 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-207 has to be applied once only. Care must be taken to ensure that this single application gives adequately dense coverage.
Tightly re-seal container immediately after each use.

Important Note:
If Sika® Primer-207 is used below 5 °C further testing under worst case conditions are mandatory.
Sika® Primer-207 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 pretreatment operation is completed the cap has to be screwed on.
Dispose the product of approx. one month after opening if used frequently or after 2 months in case of infrequent use. For 100 ml pack sizes dispose it of 2 weeks after opening. 30 ml cans, stix and tubes 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.
