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 Sikas 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.
Usage:
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 manufacturers 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.
Application:
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.
Features:
Sika Primer-207 is a versatile, pigmented, solvent-based primer designed to improve adhesion across a broad spectrum of substrates including glass, ceramics, plastics, painted surfaces, and metals. Its unique formulation reacts with moisture to form a thin, reactive layer that acts as an effective intermediary between substrates and adhesives, ensuring reliable bonding performance. This primer is especially suitable for preparing bond faces before applying Sika's 1-component polyurethane adhesives, providing excellent adhesion without the need for prior activation on many materials. The primer's fluorescence under long-wave UV light allows for in-process quality control, making application tracking straightforward for professional users.
Application is simple: shake the container thoroughly until the mixing balls rattle freely, then apply a thin, even coat using a brush, felt, or foam applicator. Ideal surface and ambient temperatures range between 15°C and 25°C to ensure optimal adhesion. Since only one application is necessary, care should be taken to provide a sufficiently dense coverage to maximize bonding strength. The primer should be used immediately after opening, with the container resealed tightly to prevent contamination or evaporation.
Designed for use by experienced professionals, Sika Primer-207 requires testing on actual substrates to verify compatibility and adhesion quality. It is recommended to perform preliminary tests, particularly on materials prone to stress cracking, to confirm suitability. The primer's features include enhanced adhesion on various substrates, UV fluorescence for quality control, and ease of application, making it a reliable choice for industrial bonding tasks where durability and adhesion are critical.
