Autoshield Activator: A Technical Overview
Autoshield Activator is a clear, fast-drying adhesion promoter formulated to enhance bonding strength between polyurethane adhesives and smooth, non-porous surfaces like glass and painted substrates. Ideal for automotive windscreen installation, panel work, and industrial glazing, this activator ensures a secure bond by chemically prepping the surface. It applies easily using a cloth or tissue, evaporates quickly, and is effective in temperatures ranging from +5°C to +40°C. When used correctly, it improves long-term durability and minimises the risk of bond failure.

Best Practices: Do's & Don'ts
Do
- Apply sparingly with a clean cloth or lint-free tissue
- Use only on clean, dry, grease-free surfaces
- Allow full evaporation before adhesive application
- Store in original sealed container in a cool, dry place
Don't

Applications in Practice: Trade Scenarios
For Automotive Glaziers (On-Site Installer): Reliable Windscreen Bonding
The Engineering Challenge
Automotive glaziers often struggle with adhesion to factory-coated glass, especially under time pressure and in fluctuating ambient conditions.
The System-Based Solution with Autoshield Activator
By applying Autoshield Activator sparingly with a cloth, the surface becomes chemically receptive to PU windscreen adhesives. Allow 5 minutes for evaporation before bonding.
Best Practice Note
Always check the activator is clear before use. Apply in shaded, ventilated conditions and avoid over-wiping to prevent residue build-up.
For Panel Beaters (Remedial Specialist): Paint Prep for Bonding
The Engineering Challenge
Adhesion to modern automotive finishes and primers can be inconsistent, risking lift or peel in bonded panel repairs.
The System-Based Solution with Autoshield Activator
Use Autoshield Activator to pre-treat painted or lacquered surfaces before applying structural PU adhesives. This ensures consistent chemical bonding.
Best Practice Note
Avoid applying over dusty or freshly waxed paint – clean thoroughly and use lint-free cloths to prevent contamination.

Frequently Asked Questions
How do I apply Autoshield Activator correctly?
Autoshield Activator should be applied using a clean, lint-free cloth or tissue. Apply sparingly to the bonding surface and allow it to evaporate fully (typically under 5 minutes) before applying the polyurethane adhesive. Avoid over-wiping or pooling on the surface.
What surfaces is Autoshield Activator suitable for?
Autoshield Activator is designed for use on glass and lacquered (painted) surfaces. It is especially effective for windscreen installations and other smooth, non-porous automotive surfaces that require strong bonding with polyurethane adhesives.
Can Autoshield Activator be used in cold or hot weather?
Yes, Autoshield Activator can be used within a temperature range of +5°C to +40°C, making it suitable for most Australian climates. Always ensure proper ventilation and surface dryness in extreme conditions to maximise adhesion performance.
What does it mean if Autoshield Activator turns milky?
If the liquid has become milky or cloudy, it has absorbed moisture from the air and should not be used. Discard any contaminated product and open a new container to avoid adhesion issues or failures.
Is Autoshield Activator compatible with all PU adhesives?
Autoshield Activator is compatible with most polyurethane windscreen adhesives, especially those supplied by Adheseal. Always test for compatibility when using unfamiliar products or consult technical support for guidance.

Applying Autoshield Activator: Enhanced Protocols & Best Practices
-
1. Prepare the Surface
Ensure all surfaces are clean, dry, and free from contaminants such as grease, dust, or release agents before applying Autoshield Activator.
Method A: Glass Cleaner
Use an approved automotive glass cleaner to remove dirt and oils from the surface. Dry with a clean lint-free cloth.
Method B: Solvent Wipe
Use isopropyl alcohol (IPA) or an appropriate solvent to degrease the surface if heavy contamination is present. Allow to dry fully before proceeding.
Timing: Allow surface to air dry completely before application.Pro Tip: Do not apply the activator on visibly wet or dusty surfaces — moisture will reduce adhesion strength. -
2. Apply Autoshield Activator
Apply a small amount of activator to a clean, dry, lint-free cloth or tissue and gently wipe the bonding area in one direction.
Method A: Manual Wipe
Use circular or linear motion with a fresh cloth for each application to avoid contamination.
Method B: Single-Use Tissue
Use a single-use paper tissue for small applications to maintain hygiene and control dosage.
Timing: Wipe gently and avoid reapplying over the same area.Pro Tip: Apply sparingly. Excess activator may leave residue that affects bonding strength. -
3. Allow Full Evaporation
Let the surface flash off completely before applying any adhesive. Do not bond while the surface is still wet with activator.
Passive Drying
Leave treated surface exposed to ambient air. Full evaporation typically occurs in under 5 minutes depending on conditions.
Timing: Wait 3–5 minutes before applying adhesive.Pro Tip: Never use heat to speed up drying — this may degrade the active bonding agents. -
4. Apply PU Adhesive
Once the activator has fully evaporated, apply the compatible polyurethane adhesive according to its own application guidelines. Proceed with assembly or installation.
Compatible Systems
Autoshield Activator is designed for use with Adheseal’s full range of windscreen adhesives and PU-based sealants.
Timing: Adhesive should be applied immediately after activator drying for best bonding.Pro Tip: Do not delay bonding after surface prep — prolonged exposure can allow dust or vapour contamination to interfere with adhesion.
Limitations & Safety
Product Limitations
Do not use if the activator liquid has turned milky – this indicates moisture contamination and will compromise adhesion.
Autoshield Activator is not suitable for porous surfaces like timber, bare concrete, or rough plastics without specialist primers.
Product performance may degrade if stored above 30°C or exposed to sunlight in unsealed containers.
Not recommended for bonding structural metal-to-metal joints without additional primer or mechanical fixings.
Safety & Handling Requirements
Personal Protective Equipment
Wear nitrile or chemical-resistant gloves and safety glasses when applying. Avoid prolonged skin contact and ensure all application personnel are properly trained.
Ventilation Requirements
Use only in well-ventilated areas. Avoid inhaling vapours, especially in confined or poorly ventilated spaces such as enclosed vehicle cabins or body repair bays.
Fire & Handling Precautions
Keep away from open flames, sparks, and heat sources. Store in tightly sealed original containers away from ignition sources. Do not smoke while using the product.
Emergency First Aid
Eyes:
Flush immediately with plenty of clean water for at least 15 minutes. Seek medical attention without delay.
Skin:
Wash affected area thoroughly with soap and water. Remove contaminated clothing.
Inhaled:
Move to fresh air immediately. Keep at rest and seek medical advice if symptoms like dizziness or headaches occur.
Swallowed:
Do NOT induce vomiting. Rinse mouth and seek urgent medical attention.
Seek medical attention immediately in all cases of serious exposure.
Autoshield Activator Application Guide
Automotive Glass (Windscreens)
Surface Preparation
Ensure the glass is clean, dry, and free of dust, grease, or fingerprints. Clean first with a suitable glass cleaner. Wipe with Autoshield Activator using a clean, lint-free cloth. Allow to dry completely before bonding.
Primer Requirements
No primer typically required
Activator is used in place of primer on glass for PU adhesive systems.
Lacquered / Painted Metal Surfaces
Surface Preparation
Remove any surface contaminants such as wax or polish. Wipe the painted surface with a clean cloth and Autoshield Activator. Do not oversaturate. Allow to flash off completely before adhesive application.
No primer typically required
Autoshield Activator is sufficient for lacquered surfaces if applied correctly.
Plastic-Coated Substrates
Surface Preparation
Test adhesion in an inconspicuous area. Clean thoroughly to remove oils and residues. Apply Autoshield Activator and allow to dry. Bonding performance may vary depending on plastic type.
Primer recommended for optimal adhesion
For critical applications, a dedicated plastic primer may be used in conjunction with Autoshield Activator.
Contact Adheseal Technical ServicesBare Metal (Steel / Aluminium)
Surface Preparation
Lightly abrade the surface if necessary. Remove all traces of oil, rust, or debris. Wipe with Autoshield Activator and allow to evaporate fully before applying adhesive.
Primer recommended for critical joints
Use of a corrosion-inhibiting primer may be beneficial in exposed or structural bonding areas.
