Whenever you’re getting to know someone or something, it’s helpful to get some background information. So how about a little bio on the technology behind Clear Bra.
Automotive Paint Protection Film is a transparent, urethane material. Urethane technology was developed during the Vietnam War, when U.S. helicopters were crashing due to damage on the leading edge of rotor blades. The military worked with 3M to develop a technology that would be lightweight, but resilient, and could be replaced at the fraction of the cost of replacing an entire rotor blade (or a crashed helicopter for that matter). In the 1970s, the military expanded its use of urethane films to the noses of fighter jets, and because the technology has been so successful and efficient, 3M still manufactures a variety of urethane films for military and aerospace purposes to this day.
In the 1980s, NASCAR saw how urethane technology could be beneficial in protecting the front half of race cars. Advertisers pay a lot of money to get their decals plastered on the front of fast cars, and I’m sure they weren’t too keen on those decals getting peppered by rock chips.
During the 1990s, urethane films became available to the general consumer for automotive protection. Since then the technology has been continually refined and improved, and has been enthusiastically welcomed across the automotive industry. Today Paint Protection Films are OEM approved by virtually all automotive manufacturers.
What is used to make Xpel Paint Protection Film? The technology behind clear bra
If you’re going to wrap something around your fine new vehicle, you’ll want to know not only where it came from, but what it is exactly. Let’s talk a little bit more about what’s inside a sheet of Paint Protection Film. The key ingredient is urethane, a powerful and versatile polymer made from carbamate links. As a compound, it has unique attributes: It is lightweight and transparent, like plastic. But unlike plastic it is not brittle or susceptible to tears and cracks. It has a high resistance to impact, abrasion, and corrosion. It is also incredibly flexible, and can return to its natural shape after being stretched or disfigured.
Given the polymer’s diverse and advantageous attributes, it has a wide variety of industrial and recreational applications. Urethane is used in the household caulk with which you line your bathroom tiles, because it seals spaces from moisture and prevents the growth of mildew or fungus. It can also be found coating boats and underwater cables to prevent damage. It is used in various sporting equipment parts, from football pads to surfboard fins. Its strength and resistance to wear and tear makes it an ideal component for manufacturing and mining equipment. As we mentioned earlier, urethane is still used to protect various parts of military and aerospace equipment.
The applications of urethane as a polymer are broad, but today we are talking about your car, and for the benefit of your car, urethane serves as a central ingredient in a clear film around 8 mils (0.008 inches) thick.
In addition to the central layer made up of urethane (or polyurethane), a quality Paint Protection Film has at least two other layers. First, the top is lined with clear coat made up of elastomeric polymers. As we mentioned above, this is the part that enables a good film to heal itself from small scratches. But it does much more. The clear coat on a good film will have a low surface energy, which prevents organic compounds, like bugs or bird droppings, from bonding with the film.
Second, the bottom is lined with an acrylic adhesive that is designed to be flexible, so that it can be stretched and wrapped around every contour or your vehicle; durable, so that the film will not detach over time; and invisible, so that it will not affect the look of the paint.
