Adhesion promoters are compounds added to polymer formulations to enhance the adhesion between different materials or between the polymer and a substrate. Here are some commonly used adhesion promoters in polymers
Benefits of Adhesion Promoters
| Improved Bond Strength | Compatibility Enhancement |
| Surface Activation | Prevention of Delamination |
| Corrosion Protection | Enhanced Performance |
| Processability | Cost Reduction |
