Coated Black Foils & Films

Acktars tiefschwarze Beschichtungen sind nicht nur als Direktbeschichtung erhältlich, sondern auch als tiefschwarz beschichtete Folie oder Film.
Die tiefschwarzen Folien ermöglichen dem Nutzer, von der Leistungsfähigkeit der Acktar Beschichtungen zu profitieren,
ohne die betreffenden Teile an Acktar liefern zu müssen.
Das ist eine optimale Lösung für sehr hohe Stückzahlen, übergroße Teileflächen und für kontaminierte Umgebungen, in denen die lichtabsorbierende Oberflächen-Beschichtung regelmäßig erneuert werden muss.
Die tiefschwarz beschichteten Folien sind mit oder ohne zusätzliche Klebeschicht erhältlich – als Bögen, Stanzform-Aufkleber oder auf Rolle.

Application of Acktar Coated Black Foils and films

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.
