Understanding Adhesive Films
What Are Adhesive Films?
Adhesive films are specialized materials designed to bond two surfaces together with precision and strength. These films often come in thin layers and incorporate various adhesive properties to meet specific bonding requirements. Unlike traditional adhesives that might require mixing or curing, adhesive films are pre-formed on a carrier film and are activated through heat or pressure, making them incredibly convenient for various applications.
Commonly utilized in industries such as aerospace, automotive, and defense, these films provide a clean and consistent composite bonding solution.
