WEB EXCLUSIVE: The new Makrofol HF family of scratchproof, hard-coated polycarbonate films can be back-printed, 3D formed, trimmed, and then back-injected in a film insert molding process without damaging the coating. Applications include auto interiors, appliances, IT equipment, and other electrical/electronic applications. The key is the new DualCure coating, which initially is partially pre-cured, so it can withstand thermoforming or high-pressure cold forming into deep draws and narrow radii. After forming, the film receives a final UV cure to harden the coating. The films’ supplier, Bayer Films Americas, Berlin, Conn., says that “before now, there were virtually no scratch-resistant coatings that could withstand forming without suffering damage.” Before now, it was necessary to print and form and then put the film through a special coating line, which required large investment and maintenance costs. The first grade in this family is Makrofol TP 278, which has a 1H pencil hardness. Future plans include matte-finish films for car interiors and UV-stable films for large external car body parts.
