SIKA Automotive Urethane Primer 207 AGR One Step — 100ml, Fast-Flash & UV‑Fluorescent Coverage

SIKA 207 AGR One Step is a solvent-based urethane primer formulated to etch and activate pinchwelds, glass bonding faces and encapsulated parts for reliable adhesion before applying 1-component polyurethane adhesives.

SIKA 207 AGR One Step automotive urethane primer comes in a 100ml bottle and is designed for professional vehicle glass installation and body repair preparation. It creates a thin, reactive film by chemically interacting with moisture, improving wetting and bonding for SIKA’s polyurethanes. The primer’s quick flash time and UV-fluorescent marker property help technicians inspect coverage during the installation process.

How does SIKA 207 AGR prepare surfaces for auto glass installation?

SIKA 207 chemically etches exposed metal, painted edges and encapsulated frames to promote strong adhesion between the substrate and one-component polyurethane adhesives. It removes microscopic contaminants and forms a reactive intermediate layer that improves adhesive wet-out and long-term bond consistency.

• Creates a thin reactive film that links substrate and adhesive
• Etches metal and painted pinchwelds for better mechanical grip
• Works on framed plastic or metal encapsulations prior to bonding
• Fluoresces under long-wave UV to verify coverage

What are the application steps and flash time I should expect?

Apply SIKA 207 to clean, dry bond faces following manufacturer instructions and allow a brief flash time before adhesive application. The primer reacts quickly with moisture; typically a five-minute flash time is recommended, and the opened product remains usable for 1–3 weeks depending on storage and humidity.

• Clean surfaces of grease, dirt and loose paint before priming
• Apply sparingly and evenly to bond faces—avoid excess
• Wait about five minutes for the primer to flash and react
• Confirm coverage under long-wave UV if available

Which substrates and repairs is this primer suitable for?

SIKA 207 AGR is formulated for automotive pinchwelds, glass edges and encapsulated parts made of metal or plastic. It is intended for professional body shops and glass installers preparing new paint or exposed metal after glass removal to help prevent rust and ensure proper adhesive performance.

• Exposed metal pinchwelds after windshield removal
• Encapsulated frames of plastic or metal parts
• Glass bonding faces prior to polyurethane adhesive application
• Body prep after painting where adhesive will be applied

What safety and handling should I follow when using this product?
