Instructions for Use
- Surface Preparation: Ensure that the surfaces to be bonded are clean, dry, and free from dust, grease, or any contaminants. Proper surface preparation is crucial for optimal adhesion.
- Application of Adhesive:
- Manual Application: Apply the adhesive evenly on both the upper and sole using a brush or roller.
- Spray Application: For a more uniform application, use a spray gun. The high solid content allows for efficient coverage with less consumption.
- Drying: Allow the adhesive to dry naturally at room temperature or use drying tunnels to speed up the process. The recommended drying temperature is between 40-50°C. Ensure the adhesive is completely dry before proceeding to the next step.
- Activation: Activate the adhesive by heating the bonded surfaces in a heating chamber. The recommended activation temperature is between 70-80°C. The activation time may vary depending on the color and material of the upper and sole.
- Bonding:
- Align the upper and sole carefully.
- Press the surfaces together using a press machine while they are still warm. Apply a pressure of approximately 2-4 bars for 15-20 seconds to ensure a strong initial bond.
- Curing: Allow the bonded shoes to cure at room temperature. The adhesive will continue to strengthen over time, providing a durable and long-lasting bond.
Tips for Optimal Results
- Storage: Store the adhesive in a cool, dry place away from direct sunlight. The recommended storage temperature is between 10-30°C. Ensure the container is tightly sealed when not in use
- Cleanup: Easily clean application tools and equipment with water after using the adhesive.
By following these tips, you can achieve optimal performance and durability with AJBASPAR’s waterborne polyurethane adhesive for footwear.
