For more than half a century now, people have colored the windows of their cars and their houses, but do they know how window stain has begin? The history of dyeing windows can be dated from the 1960s and 70s when the first protective films were first used in the manufacture of tempered glass windows for automobiles. These first films were designed to be as transparent as possible, but the demand for colored films quickly increased.
In the late 1970s, limos from across the country began using dark shades to protect the privacy of those driving in the back. Black dyes were well over 80% in some cases. Countless people liked the idea of privacy that the tinted windows provided them with. However, these darker hues have made it harder to see and, as a result, many accidents have occurred.
In the early 1980s, virtually all states in the United States had developed their own laws regarding the use of darker shades on cars. However, at that time, window staining was available at all levels from 5% to 70%. There were also many different colors to choose from as well. However, the most advanced window skin films we see today did not start to be marketed until the mid 90s.
One of the most popular and expensive films available today is one that is based on ceramics. The film that is coated with a thin film of titanium dioxide, aluminum oxide or a mixture of both is capable of reflecting the harmful UV rays of the sun while letting it pass The rest of the visible light spectrum. They also had the ability to reflect the warmth of the sun that keeps the interior of a car or refrigerator at home during the hot summer months.
The hue industry has grown by leaps and bounds over the years. While the simplest movies are always available and very affordable, there are many other superior options to choose from these days. A company even offers a polarized tinted film which, rather than blocking light, intensifies certain bandwidths of the visible light spectrum. This polarization technique is visible on the goggles that help the markers to see more clearly their target.
We already have movies that would prevent the glass from breaking into small pieces, but maybe the next generation of window dyes will completely prevent the glass from breaking in the first place.
