For pre-treating auto glass and vehicle body bond faces before applying Adheseal Autoshield 1-FC single-component polyurethane, Autoshield GB Autoglass Primer provides a secure bond link and critical UV blockout protection. This solvent-based black primer reacts with atmospheric moisture to form a thin, receptive layer that chemically bridges the substrate and the adhesive.
Upon application, the polyurethane-based solution forms a physical and chemical barrier on the substrate. To assist with quality control on busy production lines, the formula contains a luminescent agent that fluoresces under long-wave UV light (320 to 420 nm). This allows installers to visually verify complete, continuous coverage before adhesive application. Note that this luminescent effect degrades over time and is best inspected under reduced ambient light.
This primer is formulated to improve adhesion across a wide selection of automotive substrates, including:
Surfaces must be completely clean, dry, and free of grease, oil, dust, and general contaminants. Adhesion can be further enhanced by incorporating pre-treatment steps such as scuffing, cleaning, and activating.
Shake the can thoroughly until the mixing ball rattles freely, and then continue shaking for one full minute. Apply a single, thin, but covering coat using a brush, felt, or foam applicator. The ideal application and surface temperature range is between 15 °C and 25 °C. Ensure the single application achieves an adequately dense, opaque coverage.
Adheseal GB Primer enhances adhesion between automotive glass and body substrates and Adheseal's Autoshield 1-FC polyurethane adhesive. It creates a critical link layer for a durable bond.
The primer fluoresces under UV light (320-420 nm), allowing for visual in-process control of application coverage. This helps verify proper priming before the final adhesive application, reducing the risk of bond failure.
Yes, but adequate UV protection is mandatory when using Adheseal GB Primer on transparent or translucent substrates like plastics. This prevents potential issues with the substrate.
Adheseal GB Primer is moisture-reactive. Failure to reseal the container immediately after each use will compromise product quality due to moisture ingress, leading to gelling or increased viscosity.
| Application | Key benefit | Primary trades |
|---|---|---|
| Automotive glass bonding (e.g., windscreens) | Enhanced adhesion with Adheseal Autoshield 1-FC polyurethane; reliable, durable bond for vehicle safety. | Auto glass technicians, panel beaters |
| Bonding to vehicle body panels (metal, painted, E-coat, plastic) | Improves bond strength for components attached to diverse automotive substrates; prevents bond failure on mixed materials. | Automotive body repairers, vehicle manufacturers |
| Quality control in production lines | UV luminescence enables quick, visual verification of primer coverage, reducing errors and ensuring consistent application. | Automotive assembly line operators, quality assurance technicians |
Ensure bond faces are clean and dry. Shake the can until the mixing ball rattles freely, then continue for one additional minute.

This material is classified as a Class 3 Flammable Liquid. Keep away from heat, sparks, open flames, and hot surfaces. No smoking.
Wear protective gloves (nitrile rubber recommended), safety glasses, and a suitable respirator. If an inhalation risk exists, wear an organic vapour/particulate respirator meeting AS/NZS 1715 and AS/NZS 1716 requirements.
Ensure ventilation is adequate to maintain air concentrations below exposure standards. Use only in well-ventilated areas, or with local exhaust ventilation.
Store in a cool, dry, well-ventilated place, out of direct sunlight and away from foodstuffs and incompatible materials. Keep the container standing upright and tightly closed when not in use. Check regularly for leaks. Dispose of contents and container in accordance with local, regional, national, and international regulations.
Proper surface preparation is crucial for achieving the enhanced adhesion Adheseal GB Primer provides for automotive applications.
Surface prep: Surfaces must be clean, dry, and free from grease, oil, dust, and any contaminants. For optimal adhesion, consider pre-treatment processes such as scuffing, cleaning, or activating the surface as needed.
Primer: Required. Adheseal GB Primer creates a linking layer for enhanced adhesion with Adheseal Autoshield 1-FC polyurethane adhesives.
