At a Glance: Key Applications
Use Autoshield GP Primer for: Maximising adhesion in automotive glass replacements, UV blockout priming on float and ceramic glass, and bonding structural components in vehicle assemblies.
Autoshield GP Primer: A Technical Overview
Autoshield GP Primer is a moisture-reactive, black solvent-based polyurethane primer designed to boost adhesion between substrates and Adheseal’s Autoshield 1-FC polyurethane adhesive. Its unique UV fluorescence allows for inline quality control. Whether you're working with float glass, ceramic-coated glass, metal, or painted panels, this primer forms a thin but powerful link layer to ensure consistent, long-term bonding—ideal for automotive glazing and structural glass applications.
Core Features & Specifications
- Solvent-based polyurethane primer with moisture-reactive technology
- Fluoresces under UV light for quality control inspection
- Covers approximately 50 ml/m² depending on substrate porosity
- Works on a wide range of substrates including glass, Ecoats, and plastics
- Quick flash-off time—dry in under 10 minutes above 5 °C
- 9–12 month shelf life in unopened, upright storage
The Autoshield GP Primer Advantage
- Improves bond reliability and weather resistance in automotive glass installations
- Simplifies QA with visible UV detection during install
- Prevents adhesive delamination in critical bonding zones
- Reduces application errors with easy brush or felt application method
- Ideal for controlled workshop conditions (15–25 °C)
Cure Profile & Performance
Flash-off time is under 10 minutes when applied above 5 °C. In cooler climates, extended drying may be required—always verify with visual and tactile checks. Apply only one coat for best results. For environments below 5 °C, conduct field tests to validate performance.
Coverage Rate & Yield
Approximate coverage is 50 ml per square metre. Porous substrates may reduce yield slightly. One thin, complete coat is recommended—do not overapply or layer. Always reseal container immediately after use to maintain product quality.
Storage & Shelf Life Considerations
Store upright in sealed original packaging in a dry environment ≤ 25 °C. Shelf life is up to 12 months for small packaging and 9 months for 1000 ml cans. Once opened, use within 2–8 weeks depending on pack size and frequency of use. Discard if viscosity increases or gelation occurs.
Certifications & Regulatory Compliance
Not classified as hazardous by WorkSafe Australia. Always consult SDS for full handling and safety requirements. Manufactured to strict internal QC standards by Adheseal.
Frequently Asked Questions About Autoshield GP Primer
Q: How do I ensure correct application of Autoshield GP Primer on glass?
A: Clean the glass surface thoroughly to remove dust and grease. Shake the primer can until the mixing ball rattles, then apply one thin, uniform coat using a brush or felt applicator. Let flash off for 10 minutes before adhesive application.
Q: Can I use Autoshield GP Primer in cold weather?
A: Yes, but if the temperature is below 5 °C, additional testing is mandatory. Cold conditions may increase flash-off time and affect performance. Warm the surface or product slightly if practical, or apply in a controlled indoor environment.
Q: Does the primer need to be reapplied if I miss a spot?
A: No re-coating should be done. Autoshield GP Primer must be applied once only. Ensure adequate coverage during the first application. For missed areas, gently remove the existing primer layer and reapply a fresh coat.
Q: What is the significance of the UV fluorescence?
A: The primer fluoresces under 320–420 nm UV light, allowing installers to verify coverage during the process. This is especially useful in workshops with QA checks. The effect fades over time, so inspect promptly after application.
Q: What should I do if the primer starts gelling or thickening?
A: Discard it immediately. Changes in viscosity, separation, or gelling indicate moisture exposure or product degradation. Do not dilute or attempt to remix. Always reseal tightly after use and store as per guidelines.
