TSH 3130G standard, developed by Toyota vehicle company, describes test methods for determining paint quality for decorative coatings and prints in automotive interior parts.

Plastics are increasingly used in the automotive industry to make vehicles safer and more efficient. The average vehicle today is 8 percent plastic parts by weight, and given that plastic is up to 50 percent lighter than alternative materials, this represents a large number of plastic parts. Paints provide these plastic parts with decorative effects, protection, soft touch, durability, easy-to-clean qualities and more, depending on the needs of the substrate. Automotive interior paint adds emotion to a vehicle's interior plastic parts, influencing the character and quality of the driving experience, and that's why automotive companies invest in getting the perfect automotive plastic paint for interiors.
Most of the automotive coating industry relies on paints for metal surfaces, but most of a vehicle's interior elements are either coated plastic or use a special paint for automotive plastic. Comfort, noise level, aesthetic appeal, ergonomics, durability and tactility of a car are important attributes for the driver. Therefore, a soft touch is one of the most important aspects of automotive plastic wraps. In general, the following features stand out in plastic coating paint: being environmentally friendly, resistant to abrasion, resistant to weather conditions and thermal cycling, offering aesthetic diversity and being resistant to chemicals.
Not all plastic parts inside a car are made from the same plastic. The instrument panel may be PVC, the door handle EPDM, while the other parts may be of another type of plastic. At the same time, each surface has different requirements in terms of preparation or paint formulation. Therefore, there are different paint types for automotive plastics and coating processes for different plastic surfaces.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides testing services to determine the paint quality for decorative coatings and prints in automotive interior parts, within the scope of TSH 3030G standard, with its trained and expert staff and advanced technological equipment.
