CHARACTERISTICS

The 3M™ Scotchcal™ Graphic Film 3650 is a premium cast adhesive film engineered for permanent applications requiring outstanding performance, reliability, and long-term durability.

Its cast vinyl construction combined with a pressure-sensitive permanent acrylic adhesive provides excellent dimensional stability and reliable adhesion to a wide range of smooth substrates, including aluminium, glass, PMMA, polycarbonate, ABS, and painted surfaces.

The film is ideal for the production of signs, industrial labels, permanent markings, emblems, fleet graphics, and OEM applications. It is also particularly suitable for use on fuel tankers, storage tanks, and fuel dispensing equipment thanks to its excellent resistance to fuel vapours and occasional hydrocarbon spills.
