Coated Foils

Acktar Coatings are available not only as coatings applied directly to parts, but also as coated foil – with or without a self-adhesive backing - for application to surfaces by the user. These foils constitute ideal solutions for large areas or for contaminated environments where the surface needs to be periodically renewed.

The coated foils incorporate the same performance features as the directly applied coatings and are available in versions corresponding to the standard Acktar coating types – either as sheets or as roll material:

• Fractal Black^TM  for VIS and IR applications
• Vacuum Black^TM  for UV and VIS applications
• Metal Velvet^TM  for ultra-diffusive requirements in the VIS and IR
• Nano Black^TM Selective coated foil for solar-thermal applications

Preform BlackTM

Coated foil preforms supplied cut-to-shape and applied to parts by the user constitute a simple, cost effective solution – where applicable - which makes it possible to benefit from the performance of Acktar black coatings without the need to ship parts to the Acktar facility for coating.

 

Patterned Parts

Coated Foil can be delivered as tight-toleranced patterned foils for application as optical apertures, diaphragms, and other patterned applications.
