Primer-207 – Pigmented, Solvent-Based Primer for Various Substrates
Sika® Primer-207 is a solvent-based black primer that reacts with moisture and forms a thin layer. This layer acts as a link between substrates and adhesives.
Sika® Primer-207 is specifically formulated for the treatment of bond faces prior to the application of Sika’s 1-component polyurethanes. This primer might provide excellent adhesion without a previous activation step on many substrates. Sika® Primer-207 fluoresces under long-wave UV light for a limited period of time. This feature is used for in-process control.
Sika® Primer-207 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 the manufacturer’s advice and perform tests on original substrates before using Sika® Primer-207 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 to ensure adhesion and material compatibility.
Shake the Sika® Primer-207 can very thoroughly until the 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 temperatures are between 15 °C and 25 °C.
Sika® Primer-207 has to be applied only once. 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 the container immediately after each use.
