New 3M Crystal Silk Transfer Graphics Create a Tough, Low-Gloss Surface With the Feel of SilkST. PAUL, Minn., Sept. 11 -- 3M Automotive is developing a new thermal transfer process called 3M(TM) Crystal Silk(TM) transfer graphics that will allow OEMs to bring more imaging and brand identity inside their vehicles. This imaging and coating technology enables the placement of durable, silk-like designs or logos onto headrests, seat-backs, door panels, dashboards, and other interior surfaces. These unique transfer graphics are targeted for a variety of materials such as leather, fabric and vinyl. One key to the silky look and feel of the transferred graphic is a uniform upper layer of transparent glass beads or "microspheres" which results in a three-dimensional surface with light gathering capability. Below the surface layer of beads are flexible ink and thermal bonding layers. A wide range of colors is possible, including reflecting pigments which provide eye-catching color changes. The Crystal Silk transfer graphics utilize some of the same microsphere technology 3M has developed to make reflective clothing and traffic signage. This sandwich construction is carried on a thin, heat resistant film, which provides a stable base for a variety of high-definition printing processes and allows fast, easy thermal transfer. The carrier film is removed after cooling to expose the surface of microspheres, which, in turn, protects the layers of ink and adhesive from wear. A transfer process permits crisper, high definition images compared to direct printing on fabrics and other porous or textured surfaces. "The potential applications are extremely broad," says Mike Niles, market development manager at 3M headquarters in St. Paul, Minn. "Our challenge is to confirm our positive test results to date through continuing performance evaluations on the wide range of substrates in use, and to work with potential customers in bringing this product to market." 3M Automotive plans a limited release of Crystal Silk transfer graphics to automotive original equipment manufacturers for the 1999 model year. Interior applications are being targeted initially, but the process has the potential for many exterior uses because it makes surfaces resistant to abrasion, yet with a silky feel which is non-sticky to skin.
