Datum develops Polcoat coating process for finer polyimide conformal coating

November 10, 2011

Polcoat is a new award winning coating process for the deposition of fine polymer films directly on to conductive surfaces. It is a key enabling materials process for the protection of conductive surfaces reliant on nano-tech miniaturization.

Most conductors will oxidize if left unprotected. Usually a high performance polymer film is used to protect vulnerable surfaces. As products move to the nano-scale, the relatively thick films on the market become a limiting factor in further miniaturization.

Polcoat uses a new process to deliver a conformal coating of polyimide. Because the process is a finely controllable deposition process, for the first time polyimide films can be tailored in thinness to meet the precision requirements, the company said. The coating process is suitable for advanced precision engineering use in energy generation, plastic electronics, aerospace, medical and composites.

Medical products will benefit from high conformal coatings to products with complex topology that creates challenges for the coatings industry. Polyimide is a qualified material of choice for many medical applications.

Polcoat is attracting strong interest in the field of composites, the company said. It is ideal for fine coating conductive carbon materials, to make 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.
