In the standard “Toyota BSDH 1544G Test method for nail scratch resistance on paint film” developed by Toyota vehicle company, a test method is explained which is applied to determine the resistance of the coating against possible nail interventions on vehicle paints.
It is very difficult to protect a vehicle's delicate paint from harsh weather conditions. This is where paint protection film comes into play. This type of paint film provides the ultimate barrier against scratches, cracks and other environmental damage.
Originally developed by the U.S. military during the Vietnam War to protect helicopter rotor blades from debris and shrapnel, paint protection film has come a long way since then. Today, it is a staple in the automotive industry, designed to protect vehicles from environmental damage and maintain their appearance over time.
The main advantage of paint protection film is that it protects the vehicle from daily wear and tear. Paint protection film provides a clear and durable barrier between the vehicle’s paintwork and a variety of threats such as stone chips, scratches and debris. This not only helps to preserve the vehicle’s appearance and resale value, but it also saves you from costly paint repairs.
Today’s paint protection films are virtually invisible and allow the beauty of a vehicle’s paint job to shine through. Because they don’t alter the vehicle’s appearance, they are perfect for preserving its aesthetics while protecting it from potential damage.
Ultraviolet (UV) rays can be very damaging to your vehicle’s paintwork. Over time, they can cause fading, peeling and oxidation. Paint protection film is designed to help block harmful UV rays and keep your vehicle’s paintwork vibrant and unfaded.
At the same time, one of the remarkable features of paint protection films is their self-healing feature. When micro-scratches, such as fingernail scratches, occur in the film, the material can heal itself with heat, effectively erasing the scratch and returning it to its original clarity. This helps to ensure that the vehicle always has an unblemished appearance.
Finally, an advantage of paint protection film is that it is relatively low maintenance compared to other types of automotive protection. It does not require any special maintenance or polishing and can be cleaned using regular car wash techniques.
Paint protection film can be applied to the entire vehicle or to specific areas of the vehicle most prone to damage, such as the front bumper, bonnet and fenders. This provides targeted protection where it is needed, ensuring maximum effectiveness and cost-effectiveness.
One of the primary purposes of paints and coatings is to protect the underlying material and prevent corrosive damage. Therefore, it is important to have methods for assessing whether a particular coating is doing its intended job. Fingernails provide a convenient and rapid tool for such assessments, as well as a way to mimic the interaction of human fingers with surfaces, much like the everyday contact of human fingers.
The test method described in this standard is performed by simply placing a fingernail on the surface and making a quick scratch. A properly cured and abrasion resistant coating is expected not to scratch.
The way the nail test is performed can be categorized into indentation, cutting and scraping actions, which vary depending on how the nail interacts with the surface. Each method gives an idea of the hardness of the surface and how resistant it is to abrasive action. Although these tests are most easily performed with an actual nail, a similar object can usually be used.
