Coated Black foils and films | Acktar black coatings

Coated Black Foils & Films

Acktar Coatings are available not only by direct application to parts, but also as coated foil or film.

The coated foils enable the customer to benefit from Acktar coatings performance without sending the parts to Acktar.

This is an ideal solution for very large quantities, over-sized part areas and for contaminated environments where the light absorbing surface needs to be periodically renewed.

The black foil coating available either with or without an adhesive backing as sheets, die-cuts or roll.
