Tiger Seal adhesive is a high-strength, flexible sealant and adhesive widely used for bonding and sealing in various applications, particularly in automotive and construction. Proper application is key to achieving a durable and effective bond.
Preparing for Application
Before applying Tiger Seal, meticulous preparation of the surfaces is crucial to ensure optimal adhesion and long-lasting results.
Essential Surface Cleaning
- Remove Debris: Ensure all loose debris, dust, dirt, and old sealant residues are thoroughly removed from the bonding surfaces. Use a stiff brush, scraper, or appropriate cleaning tools.
- Degrease: Clean the surfaces with a suitable degreaser or cleaner to eliminate oils, grease, waxes, and other contaminants. Allow the surface to dry completely before proceeding.
- Roughen (if necessary): For certain materials, lightly abrading the surface can improve mechanical keying, though always consult the product's specific guidelines for material compatibility.
Applying Tiger Seal Adhesive
Once the surfaces are clean and dry, the application process can begin.
Loading and Nozzle Preparation
- Insert Cartridge: Place the Tiger Seal cartridge into a standard cartridge caulking gun. For larger projects or professional use, a pneumatic caulking gun can offer more consistent application.
- Cut Nozzle: Cut the nozzle at a 45-degree angle to the desired bead size. A smaller cut provides a finer bead, while a larger cut delivers more material for wider joints or stronger bonds.
Application Method
- Manual Caulking Gun: Apply the adhesive with steady, even pressure, maintaining a consistent bead size along the joint or bonding area.
- Pneumatic Caulking Gun: If using a pneumatic version, operate it at approximately 108 PSI (6 bar) for controlled and consistent material flow.
- Continuous Bead: Always aim for a continuous, uninterrupted bead to ensure a complete seal and bond.
Bonding and Tooling
- Firm Bonding: Immediately after applying the adhesive, and critically, within the skin formation time (the period before the adhesive surface begins to cure), press the materials to be bonded firmly together.
- Mechanical Fixing: For maximum bond strength, it is often beneficial to mechanically fix or clamp the materials together until the adhesive begins to cure or has fully set. This ensures consistent contact pressure during the initial bonding phase.
- Tooling: To achieve a smooth, professional finish, tool the applied bead with water only before the skin formation occurs. This helps to shape the sealant and ensure good contact with the substrate. Avoid using solvents or other substances for tooling, as they can compromise the adhesive's performance.
Curing and Finishing
Understanding the curing process is vital for the long-term performance of your bond.
Skin Formation and Full Cure
- Skin Formation Time: This is the critical window during which bonding and tooling must be completed. This time can vary depending on temperature, humidity, and the specific formulation of the product.
- Full Curing: Tiger Seal typically cures by reacting with atmospheric moisture. The full curing time can range from hours to several days, depending on environmental conditions (temperature, humidity) and the thickness of the applied bead. Always allow sufficient time for full cure before subjecting the bond to stress.
Post-Application Care
- Cleanup: Remove any excess uncured adhesive immediately with a suitable solvent (e.g., isopropyl alcohol or white spirit). Once cured, the adhesive will need to be removed mechanically.
- Protection: Protect the newly applied adhesive from water, dust, and significant movement during its initial curing phase.
Best Practices for Optimal Performance
To maximize the effectiveness and lifespan of your Tiger Seal application, consider these tips:
| Aspect | Best Practice | Detail |
|---|---|---|
| Environment | Apply in moderate temperatures and humidity. | Extreme conditions can affect cure time and bond strength. |
| Ventilation | Ensure good ventilation, especially in enclosed spaces. | Many adhesives release volatile organic compounds (VOCs) during cure. |
| Storage | Store cartridges upright in a cool, dry place, sealed tightly. | Prevents premature curing of remaining material. |
| Test Application | Always perform a small test application on an inconspicuous area first. | Verify compatibility and appearance with specific materials. |
| Material Support | Use temporary supports or clamps for heavy components during curing. | Prevents slippage and ensures a strong, uniform bond. |
Tiger Seal, as a polyurethane-based adhesive and sealant, provides excellent adhesion to a wide range of materials, including metals, plastics, wood, and concrete, making it a versatile choice for many projects.
