Sika Primer-207 - Solvent-Based Adhesion Enhancer

Sika® Primer-207 is a high-performance, solvent-based black primer designed to enhance adhesion on a wide variety of substrates. It forms a moisture-reactive layer that creates a strong bond between materials and adhesives.

This primer is formulated specifically for use with Sika’s 1-component polyurethanes, offering excellent adhesion without needing a prior activation step for many surfaces. It also fluoresces under long-wave UV light, which is useful for in-process monitoring.

Usage:

Sika® Primer-207 improves adhesion on various substrates, including float glass, ceramic-coated glass, plastics, pre-coated materials, painted surfaces, E-coats, and metals. For materials that may be prone to stress cracking, it is advised to consult the manufacturer and conduct tests on original substrates prior to application.

This product is intended for use by experienced professionals only. It is crucial to perform tests under actual conditions to verify adhesion and compatibility with materials.

Application:

Before use, thoroughly shake the Sika® Primer-207 can until mixing balls rattle freely, then shake for an additional minute. Apply a thin, even coat using a brush, felt, or foam applicator.

Optimal application and surface temperatures are between 15 °C and 25 °C. Only one coat is necessary, so ensure adequate coverage to achieve the desired results. Reseal the container immediately after each use to preserve the product.
