Footwear Adhesive Selection by Application

The Adhesive Application Process

Understanding the application process helps manufacturers achieve consistent, high-quality bonds.

Step 1: Surface Preparation

Proper surface preparation is essential for a strong bond. The surfaces to be bonded must be:

• Clean – free from oil, grease, dust and other contaminants
• Dry or appropriately conditioned – follow the adhesive and substrate requirements
• Properly prepared – surface treatment, roughening or activation may be required for some materials
• Suitable for bonding – follow the adhesive manufacturer's preparation instructions

Step 2: Priming (if required)

Some materials may require a primer to improve adhesion. Primers prepare the surface and enhance bond strength. For TPR or rubber soles, Citifix TPR 1116 and Citifix TPR 1112 are used as primer systems. For EVA substrates, Citifix EVA 1138 is recommended.

Step 3: Adhesive Application

Apply the adhesive according to the manufacturer's recommended application method, which may involve one or both surfaces depending on the formulation. For synthetic rubber-based adhesives, Citifix SR-900 FW and Citifix SR-500 FW are commonly used for bonding rubber, leather, EVA, rexine, foam and canvas. For PU-based bonding, Citifix PU 1010 and Citifix PU 3030 are suitable for PVC, PU, EVA, TPR and leather.

The adhesive should be applied:

• Thinly and evenly – apply the quantity and film thickness specified for the adhesive and substrate
• Within the open time – before the adhesive starts to dry

Step 4: Drying

Allow the adhesive to dry for the recommended time. Drying times vary by formulation. Some PU adhesive systems require heat activation before bonding. The required activation temperature depends on the adhesive formulation and substrate, so manufacturers should follow the supplier's TDS and validate the process on their actual materials.

Step 5: Bonding

Press the surfaces together with uniform pressure. For heat-activated systems, bonding should be done when the substrates are at the temperature specified in the TDS.

Step 6: Curing

Allow the bond to cure fully. Full cure times vary by formulation and process conditions. During curing:

• Maintain pressure if required
• Avoid exposing the bond to stress
• Allow adequate ventilation

Key Quality Parameters for Footwear Adhesives

Manufacturers should evaluate adhesives based on these quality parameters.

1. Peel Strength

Peel strength measures the force required to separate a bonded assembly under a specified test method. Results should be compared using the same test conditions and substrate combination.

2. Heat Resistance

The adhesive should maintain its bond strength at elevated temperatures. This is particularly important for footwear exposed to hot environments.

3. Cold Flexibility

The adhesive should remain flexible at low temperatures. Rigid adhesives can crack in cold conditions.

4. Water Resistance

The bond should withstand exposure to water without weakening or failing.

5. Aging Resistance

The adhesive should maintain its properties over time without becoming brittle or losing strength.

6. Open Time

Open time is the period during which the adhesive remains tacky after application. Longer open times provide more flexibility in production but may slow down the process.

7. Substrate-Specific Testing

Testing should be performed on the actual upper-and-sole material combination rather than relying solely on a generic adhesive specification.

Footwear Adhesive Testing and Quality Standards in India
