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.
The low surface energy simply prevents conventional adhesives from making intimate contact with the substrate surface and this reduces adhesion.
This article will help you understand why these substrates are difficult to join and offers insight into possible solutions including:
» Optimizing interface
» Appropriate surface treatment processes
» Right selection of adhesive system
