3M™ Cooling Film is a durable, passive cooling film designed to help reduce solar heat gain on exterior transportation and equipment surfaces. Featuring over 85% solar reflectivity and 91% emissivity, the film helps limit heat absorption from direct sunlight while promoting radiative cooling, which can contribute to lower substrate and interior vehicle temperatures.
Engineered for demanding exterior applications, 3M™ Cooling Film combines excellent solar performance with the flexibility needed to conform to compound curves, corrugations, and rivets. Its pressure-activated adhesive allows the film to slide, tack, snap up, and reposition during installation, while non-visible air-release channels help provide fast, smooth, bubble-free dry applications.

3M™ Cooling Film FAQ
Q: Where do you apply Cooling Film?
A: On exterior vehicle roofs, where it has the greatest impact on reducing heat.
Q: How is it different from a graphic film?
A: It's built for long-term thermal performance, not just appearance, and carries a longer warranty under high-sun, horizontal exposure than a standard graphic film.
Q: Is it printable, can you add graphics on top?
A: No, it's not digitally printable. Electro-cut films or 3M graphic films can go on top for numbers or decals, but any material layered on top will reduce the cooling effect.
Q: Can it go over curves or corrugation?
A: Yes, it's flexible and conforms to curves, corrugation, and rivets.
Q: How do you clean and maintain it?
A: It has a dirt-resistant surface. We recommend washing the roof at least four times a year to maintain peak performance.
Q: What's the warranty?
A: A 5-year 3M™ MCS™ Warranty, regardless of zone or film orientation.
