Use Autoshield GP Primer for: Enhancing adhesion of polyurethane adhesives to auto glass, ceramic-coated glass, plastics, and metals.
Autoshield GP Primer is a high-performance, solvent-based black primer designed to improve the adhesion of polyurethane adhesives on a wide range of substrates, particularly in automotive glass applications. This primer reacts with moisture to form a thin, durable layer that acts as a crucial link between the substrate and the adhesive, ensuring a strong and lasting bond. Its formulation is specifically tailored for use with Adheseal’s NP60 primerless polyurethane adhesive, providing excellent adhesion without the need for additional activation steps on many surfaces. The inclusion of UV detectable properties allows for easy in-process quality control, ensuring comprehensive coverage and consistent application.

Technical Overview
Autoshield GP Primer is formulated to provide a reliable and durable bond in automotive glass applications. Its solvent-based polyurethane solution ensures excellent wetting and penetration on various surfaces, creating a strong foundation for adhesive application. The primer's ability to react with moisture forms a thin, robust layer that enhances the adhesive’s performance, particularly in challenging environmental conditions.
Chemical Properties: Solvent-based polyurethane solution that reacts with moisture to form a bonding layer.
Application Temperature Range: 5°C to 40°C (41°F to 104°F). Ideal application and surface temperature are between 15°C and 25°C (59°F and 77°F). Ensure surfaces are clean, dry, and free from contaminants before application.
Application Information
-
Required Tools: Brush, felt, or foam applicator, UV light source (320-420 nm), cleaning solvents.
-
Trade-Specific Tips: Shake the primer can thoroughly before use. Apply a thin, even coat. Reseal the container immediately after use to maintain product quality. Use UV light to verify coverage.
-
Common Issues and Solutions: Gelling or increased viscosity indicates the primer should be discarded. Ensure proper resealing to prevent moisture contamination. For transparent substrates, ensure adequate UV protection.
