Reliable adhesion of polyurethane (PU) adhesives to smooth glass and lacquer demands the right preparation. Without it, you chase callbacks and risk bond failure on critical automotive and industrial applications. Autoshield Activator AP1001 provides the chemical activation needed for strong, lasting adhesion where it matters most. It ensures your PU adhesive grabs hard and holds fast.
Autoshield Activator AP1001 is not a general primer. It is an adhesion promoter specifically formulated to chemically activate non-porous glass and lacquer surfaces for optimal bonding with polyurethane (PU) adhesives. This targeted formulation prevents common adhesion failures on smooth, often challenging substrates, ensuring the full performance of your chosen PU adhesive system. It's the critical first step in a reliable direct-glazing sequence.
The activator’s clear colour ensures no visible lines or discoloration, critical for transparent substrates like glass. An application temperature range of +5°C to +40°C provides a broad working window, accommodating diverse Australian climates and workshop conditions. With an 18-month shelf life, the product maintains potency when stored correctly, ensuring consistent performance for scheduled projects.
Start with a dry, clean surface, free from dust or grease. Apply Autoshield Activator AP1001 sparingly with a clean applicator or rag, wiping the surface effectively. Work only in well-ventilated areas due to its solvent base. Do not expose treated surfaces to thermal, mechanical, or chemical influences before the activator is completely dry. For tool cleaning, use a suitable solvent or alcohol while the product is still wet.
Autoshield Activator AP1001 is engineered for demanding adhesion scenarios:
Autoshield Activator AP1001 is the mandatory first step in the Adheseal Autoshield direct-glazing system. It prepares the surface for the subsequent adhesion layers. The sequence is critical for guaranteed performance: first, activate glass and lacquer with this product; second, apply Autoshield GB Primer as a thin linking film; and finally, apply Adheseal NP-60 Autoshield polyurethane adhesive.
Autoshield Activator AP1001 is an adhesion promoter specifically designed to chemically enhance the bond of polyurethane (PU) adhesives to critical surfaces like glass and lacquer. This prevents bond failure and ensures long-term adhesion stability, crucial for applications like automotive glazing.
No. This activator is formulated for use only on glass, lacquer, and specified non-porous surfaces when preparing for polyurethane adhesive application. Always confirm suitability for your specific substrate by performing adhesion tests.
A milky appearance indicates water absorption into the product, rendering it unusable. The activator must be clear to be effective. Dispose of any milky product and use a fresh, clear batch to ensure proper adhesion promotion.
Apply Autoshield Activator AP1001 very sparingly using a clean applicator or rag. Over-application can negatively impact adhesion or cure of the subsequent adhesive. A thin, even wipe is sufficient.
| Application | Key benefit | Primary trades |
|---|---|---|
| Pre-treatment for PU adhesive to glass | Ensures reliable chemical bond, preventing premature adhesive failure on critical glass installations. | Automotive glaziers, marine fabricators, building facade installers |
| Surface preparation for PU adhesive to lacquer | Enhances adhesion to lacquered surfaces, providing a durable and robust bond for long-term performance. | Automotive body repair, industrial manufacturers |
| Adhesion promotion on non-porous surfaces | Facilitates strong, lasting adhesion of PU adhesives to various non-porous substrates where mechanical keying is limited. | General construction, industrial assembly |
Ensure all surfaces are clean, dry, and free from contaminants such as grease, dust, or release agents before applying Autoshield Activator.
Use an approved automotive glass cleaner to remove dirt and oils from the surface. Dry with a clean lint-free cloth.
Use isopropyl alcohol (IPA) or an appropriate solvent to degrease the surface if heavy contamination is present. Allow to dry fully before proceeding.
Apply a small amount of activator to a clean, dry, lint-free cloth or tissue and gently wipe the bonding area in one direction.
Use circular or linear motion with a fresh cloth for each application to avoid contamination.
Use a single-use paper tissue for small applications to maintain hygiene and control dosage.
Let the surface flash off completely before applying any adhesive. Do not bond while the surface is still wet with activator.
Leave treated surface exposed to ambient air. Full evaporation typically occurs in under 5 minutes depending on conditions.
Once the activator has fully evaporated, apply the compatible polyurethane adhesive according to its own application guidelines. Proceed with assembly or installation.
Autoshield Activator is designed for use with Adheseal’s full range of windscreen adhesives and PU-based sealants.
Danger
Autoshield Activator is a hazardous chemical. Read the SDS before use. It is a highly flammable liquid and vapour (H225). Harmful if swallowed (H302), causes skin irritation (H315), and may cause an allergic skin reaction (H317). Toxic to aquatic life with long-lasting effects (H411). Repeated exposure may cause skin dryness or cracking (AUH066).
Wear safety shoes, protective gloves (nitrile rubber recommended for intermittent contact), apron, chemical goggles, eye/face protection, and a suitable respirator. Ensure adequate ventilation is available.
Use only outdoors or in a well-ventilated area. Ensure local exhaust ventilation is sufficient to maintain air concentrations below occupational exposure standards. Avoid breathing fumes, gas, mist, vapours, or spray.
Store in a cool, dry, well-ventilated place, out of direct sunlight, and away from foodstuffs, heat, and ignition sources. Keep containers tightly closed and upright. Autoshield Activator is a Class 3 Flammable Liquid and a Schedule 5 poison; store and handle according to relevant regulations. Dispose of contents and containers in accordance with local, regional, national, and international regulations.
Proper surface preparation is critical for establishing a strong, durable bond with polyurethane adhesives.
Surface prep: Ensure surfaces are dry, clean, and free from dust or grease. Mechanical cleaning or chemical pre-treatment may be necessary depending on contamination.
Primer: Required. Autoshield Activator AP1001 enhances the chemical bond between the glass and subsequent PU adhesive layers.
Surface prep: All lacquer surfaces must be dry, clean, and free from dust or grease before application. Remove any loose or flaking material.
Primer: Required. Autoshield Activator AP1001 improves the adhesion of PU adhesives to lacquer, reducing the risk of delamination.
Surface prep: Surfaces must be dry, clean, and entirely free of dust, grease, or other contaminants. This ensures direct contact for adhesion promotion.
Primer: Required for optimal adhesion. The activator is designed to improve PU adhesive bonding on these surfaces.
