FILCO® 74012 high molecular weight epoxy film-formers are specifically engineered for application in thermoplastic matrices, such as Polybutylene Terephthalate (PBT) and Polycarbonates (PC). Characterized by exceptional high dilution and shear stability, these film-formers contribute to the production of films that are notably hard yet not brittle. This unique quality enhances fiber integrity, making them a valuable component in composite materials. Functioning as film formers, these epoxy derivatives play a crucial role in reinforcing thermoplastic matrices, ensuring durability and structural integrity in diverse applications.
