Datum have created a new coating process, Polcoat, for the deposition of fine polyimide films directly on to conductive surfaces, described as a key enabling material process for the protection conductive surfaces featuring miniaturisation.
Datum explains that Polcoat uses a new process to deliver a conformal coating of polyimide. The Polcoat process is similar to electroforming; a widely used process for coating metal substrates with protective metal coatings. Because the process is a finely controllable deposition process, for the first time polyimide films can be tailored in thinness to meet precision requirements. They say the coating process is suitable for advanced precision engineering products for energy generation, plastic electronics, aerospace, medical and composites.
Datum say Polcoat is attracting strong interest in the field of composites as it is ideal for fine coating conductive carbon materials, suitable for durable lightweight carbon composites for aerospace and military use. Polcoat is easily combined with precision alloys to make durable components for filtering and sensing applications in chemicals, food, gas and oil production.
Early stage clients have validated the benefits of Polcoat, and according to Datum, there is enormous scope for the development of future composite materials featuring the combined benefits of Polcoat with new materials.
Datum will be exhibiting Polcoat at stand 1216 at Advanced Engineering UK, at the NEC on 9th – 10th November.
