What is Quantum Film in Automotive Window Tinting?

[RyanMarie]

Quantum Film is recognized as the world's top-tier spectrally selective automotive film. Advantages of Quantum Film: 1. Quantum Film resists fading even after prolonged use, whereas ordinary films tend to fade due to sun exposure and time. The Quantum product series was successfully developed in the mid-1990s and patented, becoming the world's first dual-layer magnetron sputtered film specifically designed for the automotive window tinting market. At that time, even the highest-end automotive films contained significant dye components. 2. Superior Heat Rejection: Quantum Film features a unique dual magnetron sputtering coating process, offering better heat insulation and lower reflectivity. 3. Healthier Option: Quantum Film utilizes DuPont nano-substrate technology with twelve layers synthesized in one process, and its installation adhesive contains no volatile organic solvents such as formaldehyde or toluene.

I just had Quantum film installed on my car last year and want to share my actual experience. Quantum film is essentially a premium window film, with its most impressive feature being the magnetron sputtering technology—simply put, it precisely layers metal particles on the film to create a heat-insulating layer. I opted for the Diamond 70 series, with darker shades for the side windows. During the hottest summer days, I clearly felt the reduced burden on the AC, and my arms no longer got scorched by the sun. However, it is indeed much more expensive than regular ceramic films, costing me over 5,000 yuan at the time. The upside is its exceptional UV protection—the dashboard leather hasn't faded in two years, and there's no glare interfering with night driving. If your budget allows, I recommend trying the high-transparency version for the windshield, which doesn't compromise driving safety while still providing sun protection.

Having studied the technical features of Quantum film, it employs a heat insulation solution with multi-layered nano-scale metal coatings. Ordinary dyed films block light by coloring the film, but heat remains inside the car; metallic reflective films can interfere with mobile signals. Quantum film uses magnetron sputtering technology to control the distribution of metal particles at the atomic level, effectively blocking infrared heat without disrupting signal transmission. I measured the interior temperature before and after installation—after two hours of intense sunlight, the difference can exceed ten degrees. This technology was initially used in spacecraft, and now the civilian version maintains high clarity while reducing air conditioning energy consumption by 50%. However, be cautious as there are many low-quality imitations—always verify the official electronic warranty card.

Simply put, Quantum film is the top-tier version of automotive film, specializing in heat insulation and sun protection. As someone who drives long distances all day, I particularly care about heat insulation. They offer two main series: Diamond and Quantum. For the windshield, a light-colored film like Diamond 70 doesn’t obstruct visibility, while the side windows can be paired with a dark-tinted Quantum 19 for privacy. The most noticeable effect after installation is that the steering wheel doesn’t burn my hands in summer. When I replaced the film last year, I also tested its UV blocking rate, which was nearly 100%. Although it’s three times more expensive than regular film, it saves money on sunshades and repeated replacements. The only thing to watch out for is the installation environment—dust can affect adhesion, so it’s best to find a professional shop with a dust-free workspace.
