Ceramic IM50

The Ceramic IM50 film from 3M is built with nano-ceramic technology, ensuring strong heat rejection and long-term durability without fading. It blocks 46% of the sun's heat, making a noticeable difference in keeping your car cooler. Plus, it cuts glare by 29%, which helps when driving into the sun or facing oncoming headlights at night. Importantly, the film is signal-safe, so you won't have any issues with GPS or phone signals, and it offers nearly complete UV protection, blocking 99% of harmful rays. Every claim here is backed by 3M's own published documents, which you can check out directly through the links provided.

A lighter, heat-focused tint for hatchback side and rear glass: 46% total solar energy rejection and 76% infrared rejection in a metal-free film that leaves GPS, FASTag and phone signal alone, plus 99% UV rejection to help protect the cabin from fading.

Most cabin heat arrives as infrared and visible light. Ceramic IM films use nano-ceramic particles, not metal, to reject infrared, which is why 3M can quote 76% IRR (measured on the film alone) while the film stays light at 63% VLT. TSER, 46% here, is the broader figure: it counts the whole solar spectrum and is measured on glass, so real cars differ a little. Because the film is metal-free it does not interfere with GPS, FASTag or mobile signal. 3M's tables cover two glass types: 63% VLT on clear glass and 52% on typical green car glass. The second is closer to what you will see on the car.

At 63% VLT on clear glass (about 52% on typical car glass) this is a light tint. It does not give strong privacy, and its 46% TSER is lower than the darker IM tiers. It is made for side and rear glass, not the front windshield. Tint limits vary by state, so check current rules before choosing a level.

Have it fitted by a professional installer — 3M specifies wet application only. Clean with a neutral, abrasive-free glass cleaner and a soft cloth, and avoid sticking tapes, suction cups or stickers on the film.
