| Résumé : |
Certain polymeric substrates, such as polyolefins, fluoropolymers, and silicone rubber are difficult to bond and present challenges to both the formulator and the end-user. The main reason that these materials present problems is their low surface energy which is unlike metals, ceramics, and most other polymers. The low surface energy simply prevents conventional adhesives from making intimate contact with the substrate surface and this reduces adhesion. While finding solutions for better bonding in these substrates, the joint interface becomes the overriding concern. Proper selection of surface treatment and adhesive system for the specific substrate are the main steps involved in improving the process. These bonding mechanisms are well established and represented by important theories of adhesion. Let us discuss different aspects which you should consider while bonding low energy substrates. |
