K 2010: Protecting High-Quality Surfaces

October 27, 2010
  • Suntan lotion-resistant surface decoration thanks to in-mold laminated TROGAMID® TCR films

  • Evonik Industries, Pröll, and Niebling showcase film, color, and manufacturing process.

 

Surfaces made of TROGAMID® TCR microcrystalline polyamide films (Transparent, Chemical Resistant) are built tough. They stand up to sunlight, heat, and shock, not to mention cosmetics such as suntan lotion and other chemicals. Whether transparent or printed, they also have a luxurious look. Essen, Germany-based Evonik Industries supplies TROGAMID® TCR films in thicknesses ranging from 50 µm to 750 µm for decorating and protecting high-quality surfaces.

Durable products such as cars, lavishly decorated panels, consoles, and operational controls have to retain their appearance over the entire useful life of the vehicle. Touching these surfaces often exposes them to the detrimental effects of sweat, skin oil, and cosmetics. But even cleaning agents can damage them. Frequent temperature swings, such as when a vehicle stands under the scorching sun after a cool night, take their toll, too. All of these conditions increase the likelihood of stress cracking and clouding on the surface, which prompt customer complaints and are damaging to a company’s image.

Transparent TROGAMID® TCR films offer a remedy. Manufactured from colorless microcrystalline polyamide, and with far greater chemical resistance than other transparent plastics, these films are particularly resistant to suntan lotions and cosmetics. In accordance with VW test specifications, a study comparing the effects of hand and suntan lotions was conducted and confirmed these properties. In the test, TROGAMID® TCR films were in contact with the lotions at a temperature of 80°C for 24 hours. A material passes the test when treatment does not change it noticeably and its scratch resistance remains the same as before. Only the 50 µm specialty polyamide film passed the test in all points. Styrene acrylonitrile (SAN), polymethyl methacrylate (PMMA), and polycarbonate (PC) were tested for comparison.

Crystal-clear and colorless, TROGAMID® TCR films give designers maximum freedom in surface design and cause no color shift on back-printed designs. Resistant to weather and UV light, these top layers are non-abrasive and impart an attractive relief effect. Their scratch resistance is similar to that of uncoated films complying with the industry standard.

This brings us to the color version: We have developed printing inks and a process for in-mold laminating TROGAMID® TCR films in conjunction with Pröll KG (Weissenburg, Germany), a producer of industrial screen printing inks, and tool manufacturer Niebling Junior (Penzberg, Germany). NoriAmid, Pröll’s new printing ink system, the processing of the film, and the initial components will be presented to the public for the first time during the K’2010.
