Securing automotive glass with Autoshield 1-FC polyurethane demands uncompromising bond integrity. Autoshield GB Primer establishes the robust linking layer needed for reliable adhesion on diverse automotive glass and body substrates. Its unique UV fluorescence provides visual, in-process quality control, bringing confidence to every direct-glazing installation.
Adheseal GB Primer was formulated to prevent adhesion failure between an Adheseal Autoshield 1-FC polyurethane adhesive and automotive glass or body substrates. It is a solvent-based black primer designed to react with moisture, forming a thin, reactive linking layer between the bond face and the adhesive. Unlike general-purpose primers, Autoshield GB Primer is precisely formulated for this specific chemical system and substrate range. Its integrated UV fluorescence allows for in-process application control, ensuring complete and uniform coverage across the bond line.
Preparation begins with thoroughly shaking the can until the mixing ball rattles freely, continuing for an additional minute to ensure the black pigment and reactive components are uniformly dispersed. Apply a thin, covering coat using a brush, felt, or foam applicator. Ensure the application is single-pass and provides adequately dense coverage. The ideal application and surface temperature for best results is between 15 °C and 25 °C. After use, immediately reseal the container tightly with the inner plastic liner and screw on the cap. Never dilute or mix this product with other substances.
For in-process quality control, use a light source with a wavelength of 320 to 420 nm. The primer will fluoresce, allowing you to verify 100% coverage. Reduce ambient light (sunlight or artificial) during detection to improve visibility, but be aware the luminescent effect will degrade over time.
Autoshield GB Primer is an essential component of the mandatory 3-step Adheseal Autoshield direct-glazing system. It is step 2 in this sequence, creating the necessary linking layer after surface activation and before adhesive application.
Following this specific sequence ensures maximum adhesion performance and durability for your automotive glass installations.
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.
Apply a single, thin but covering coat using a brush, felt, or foam applicator.
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.
