Iridescent Lustre 6400 is a premium Mactac film designed for high profile applications over flat to complex curves like rivets, corrugations and other irregular surfaces. The face is a 2.0-mil cadmium-free cast vinyl offering a pearly, anodized finish that gleams in the sun. Whether used on a flat or highly complex surface, this film has been designed to conform and maintain a high bond. The product is coated with a high performance permanent, clear solvent acrylic adhesive protected with 78# bleached white kraft liner for good stability and layflat.
