BMS targets IMD with formable anti-scratch films

"This is the first member of the new Makrofol HF product family of scratchproof-coated, formable films,” said Dirk W Pophusen, head of business development in the BMS Functional Films business.

“This is our response to the recent more stringent specifications concerning the scratch resistance of printed and decorated 3D film components used, for example, in car interiors, household appliances and IT equipment," he said.

Application of anti-scratch coatings to decorated 3D-IMD components has long been a challenge for processors, requiring additional and costly processing equipment and incorporating an additional manufacturing step into an already complex multi-stage process.

The Makrofol TP 278 product uses a DualCure coating which allows the film to be cold formed to deep draw ratios and tight edge radii using high pressure forming techniques prior to final curing of the coating using UV light.

The cured coating is said to provide a 1H pencil hardness rating in the ISO 15184 500g abrasion test. It is also resistant to a wide range of everyday chemicals and cleaning agents, making it suitable for use in automotive, domestic appliance and consumer electronics applications.

The company said it is currently working on development of two further formable coatings - a matt finish for use in interior automotive applications and a UV-stabilised hardcoat for exterior bodywork parts.
