Neoprene adhesive is a type of strong and flexible glue that is commonly used to bond neoprene rubber to various materials like EVA sheet, rubber sheet, sole, and other materials. Neoprene is a synthetic rubber that is resistant to water, oil, and chemicals, making it ideal for bonding applications. Making neoprene adhesive involves combining specific ingredients to create a mixture that will adhere well to neoprene and other surfaces. Here’s a basic recipe to make neoprene adhesive:
Ingredients: Neoprene Adhesive Formula-01
| SL-No | Ingradients | Quantity-Kg |
| 1 | Toluene | 875 |
| 2 | SBPs | 470 |
| 3 | MgO | 5 |
| 4 | Petrocin Resin | 48 |
| 5 | Phenolic Resin | 55 |
| 6 | Denka, A-90 | 61 |
| 7 | Denka, M-40 | 184 |
| Antioxident- BHT | Antioxidant- BHT | 1.200 |
| Total | 1699.2 |
Solvent: A solvent is needed to thin the neoprene cement and improve its spreadability. Toluene is a commonly used solvent for
this purpose.

Safety Precautions:
Work in a well-ventilated area to avoid inhaling fumes.
Wear gloves and eye protection to prevent contact with the adhesive.
Keep the adhesive away from open flames or sparks, as the solvent is flammable.
Instructions:
Measure the ingredients: Pour the desired amount of neoprene cement base into a clean, empty container. The amount you use will depend on the size of the bonding job.
Add solvent: Add a small amount of solvent (toluene) to the neoprene cement base. The exact ratio of solvent to neoprene cement will vary depending on the manufacturer’s recommendations and the desired consistency of the adhesive. Typically, a 5:1 ratio of neoprene cement to solvent is a good starting point. Mix the solvent and neoprene cement together thoroughly.
Mix well: Stir the mixture well to ensure the solvent and cement are fully combined. Make sure there are no lumps or inconsistencies in the mixture.
Test the adhesive: Before using the neoprene adhesive on your actual project, it’s a good idea to do a test application on a small piece of neoprene or scrap material to check its effectiveness.
Apply the adhesive: Using a brush or a small applicator, spread a thin, even layer of the neoprene adhesive on both surfaces that you want to bond. Apply the adhesive to both the neoprene rubber and the material you want to attach it to.
Allow drying time: Let the adhesive dry for the time specified by the manufacturer. It is essential to follow the recommended drying time to ensure a strong and lasting bond.
Press the surfaces together: Once the drying time is complete, press the neoprene and the other material together firmly to create a strong bond. Use clamps or weights if needed to hold the pieces in place while the adhesive fully cures.
Curing time: The curing time may vary depending on the specific adhesive used, but it typically takes 24 hours for the bond to reach full strength.
Please note that the specific steps and materials required may vary depending on the type and brand of neoprene adhesive you use. Always follow the manufacturer’s instructions and safety guidelines for the best results and to ensure proper bonding.
