Coated Black Foils & Films

Acktar’s coated foils are an ideal solution for optical applications where very large quantities, oversized part areas and contaminated environments make direct coating impractical. Acktar’s black foils provide all the benefits of stray-light suppression with Acktar Black Coatings, ready-made and awaiting application.

Acktar Coatings are available as either coated foil or film, with or without an adhesive backing, and as either sheets, die-cuts, or rolls.

Welcome to Acktar, where we offer cutting-edge coated black foils and films that provide unparalleled performance for your applications. Our products enable you to benefit from our advanced coatings without the need to send your parts to us, making it an ideal solution for very large quantities and contaminated environments where periodic renewal is required.

Our black foil coatings are available with or without an adhesive backing as sheets, die-cuts, or rolls, and we offer different types with various substrate materials, thicknesses, appearance, typical spectral range, AOI range, and abrasion resistance. With conformal thin flexible foils that are suitable for plastic and metal parts and more. The foils exhibit high emissivity, low reflectance, extremely low outgassing, no particulation, vacuum, cryogenic, and cleanroom compatibility, and cleanability, our products provide the perfect solution for a wide range of applications.

Our coated black foils and films are ideal for stray light absorption/suppression, optical packaging, laser devices, infrared systems, passive thermal control, and much more. With Acktar, you can trust that you will receive high-quality, reliable products that are designed to exceed your expectations.
