3M Launches Anti-Theft Films for Car Windows

3M is introducing car window films meant to deter theft. The adhesive film holds the window together even if it’s shattered, meaning that if the window is smashed it still blocks easy entry to the car. Before bringing the film to market, 3M researched cities with high rates of theft from vehicles in countries including Brazil, Panama, Mexico, and the U.S.  Generally, thieves used hammers or crowbars to break a window and quickly take portable items such as electronics. Without the film it takes as little as three seconds to break a car window. With the film, the window will still break, but it can take several minutes of effort to gain access to the vehicle. The automobile window films are similar to 3M films used to make building resistant to hurricane winds. During development, 3M overcame classic problems of shrinking the film size and fitting it to curved glass, while retaining strength.
