For prep work on porous substrates or metal surfaces prior to sealing, Adheseal Primer 2001 is a solvent-based reactive polyurethane primer that enhances bond strength and prevents corrosion. It provides a reliable bonding surface for polyurethane and hybrid sealants on challenging substrates, and acts as a rust inhibitor on scratched metal surfaces during automotive glass and windscreen replacements.
Primer 2001 operates as an air-drying, reactive polyurethane liquid. When applied to porous materials like timber and masonry, the low-viscosity formula penetrates the surface to establish a secure chemical key for subsequent polyurethane and hybrid coatings. On metals, it seals the substrate to inhibit rust formation in areas where the protective coating has been scratched or compromised.
Apply Primer 2001 using a clean brush or cloth. Uncured primer must be cleaned immediately with acetone or xylene. Once the primer has cured, it cannot be dissolved by solvents and must be removed by mechanical means. Store the product in cool, dry conditions between 10-35 degrees Celsius.
Use Primer 2001 to ensure strong adhesion of Adheseal polyurethanes and hybrids on porous materials like timber and masonry. It is also critical for rust prevention on metal surfaces, particularly in automotive glass installations. This reactive primer creates a reliable bond and prevents common failures.
No. Primer 2001 is specifically formulated for porous substrates such as timber and masonry, and for metal where rust inhibition is required. It is a solvent-based reactive primer and its suitability for other surfaces should be verified through testing.
Primer 2001 is a highly flammable, solvent-based product with a "Danger" signal word, causing serious eye irritation and potential drowsiness. Ensure adequate ventilation or use outdoors. Consult the SDS for full safety and PPE requirements.
Apply Primer 2001 at a rate of 50-150ml per square metre. The exact amount depends on the porosity of the surface. More porous materials will require a higher consumption rate within this range to achieve proper coverage and adhesion.
| Application | Key benefit | Primary trades |
|---|---|---|
| Polyurethane and hybrid sealant bonding on timber | Ensures superior, lasting adhesion on porous timber, preventing bond failure and callbacks. | Carpenters, Joiners, Builders |
| Polyurethane and hybrid sealant bonding on masonry | Creates a reliable bond on absorbent masonry surfaces, crucial for long-term sealant performance. | Bricklayers, Stonemasons, General Builders |
| Rust inhibition for automotive glass metal frames | Inhibits rust where coatings are scratched, maintaining the integrity of the metal and sealant system. | Auto Glass Technicians |
Ensure all surfaces are clean, dry, and porous. Remove dust, grease, loose particles, and contaminants using abrasion or pressure washing if necessary.
Gently stir Primer 2001 before use to ensure uniform consistency. Do not shake or whip air into the material.
Apply a thin, even coat using a clean brush, roller, or low-pressure spray. Avoid puddling or over-application.
Allow primer to dry until it becomes tacky to the touch (usually 20–30 minutes depending on temperature and humidity).
While the surface remains tacky, apply your Adheseal polyurethane or MS sealant for maximum bond strength.
Danger: Highly flammable liquid and vapour. Causes serious eye irritation. May cause drowsiness or dizziness. Toxic to aquatic life with long lasting effects. Poison Schedule S5. Caution.
Wear safety shoes, gloves (nitrile rubber recommended for intermittent contact), apron, and chemical goggles or eye/face protection. A suitable respirator is also required to avoid inhaling vapours.
Ensure ventilation is adequate. Use only outdoors or in a well-ventilated area. Use with local exhaust ventilation or while wearing an appropriate respirator.
Store in a cool, dry, well-ventilated place, between 10-35°C, and out of direct sunlight. Keep containers tightly closed and locked up. Store away from foodstuffs and incompatible materials. Dispose of contents and container in accordance with local, regional, and national regulations. Shelf life is 12 months.
Proper surface preparation is crucial for Adheseal Primer 2001 to achieve its intended adhesion and rust inhibition performance.
Surface prep: Ensure surfaces are clean, dry, and free from dust, grease, and loose particles. Any old coatings or sealants must be removed. The surface porosity will influence consumption rate.
Primer: Required. Apply a thin, even coat at 50-150ml per square metre, adjusting for porosity. This improves the adhesion of polyurethane and hybrid sealants.
Surface prep: Clean the metal frame thoroughly. Remove any existing rust or corrosion. The primer is applied where the coating may have been scratched, inhibiting further rust formation.
Primer: Required. Apply a thin, even coat to the prepared metal surface. This provides rust inhibition under the sealant bead.
