Film adhesives are a versatile bonding option across many markets, including aerospace, automotive and assembly. Offering uniform adhesion and customized width, film adhesives can also impart flame retardancy while reducing material waste, making them a popular choice for many applications. Find out what to consider when choosing a film adhesive for your needs.
1. Application Conditions
Understand what conditions the film adhesive will be exposed to both during and after application. For example, high temperatures in an end-use application will require a film adhesive with specific temperature resistance levels.
2. Substrate Compatibility
It’s a good idea to know a film adhesive’s base polymer when considering how well it will bond to a given substrate. A polyester film adhesive is likely to offer better adhesion to a substrate of similar polyester composition.
3. Performance Needs
A film adhesive can be either thermoset or thermoplastic. Understand your performance needs ahead of time to determine which to choose. For example, a thermoset adhesive will offer increased rigidity over a thermoplastic, which will remain flexible when cured.
4. Flame Retardancy
A film adhesive can be formulated to provide flame retardancy, which is often desirable for transportation applications and safety clothing. However, it’s important to understand the capabilities of the two substrates being bonded together to determine if flame retardancy in its formulation is needed.
