Our History

The company was originally founded by Jeffrey Stewart – a brilliant magnetics engineer – when he purchased the first commercial license to sell Parylene products from Union Carbide Corporation. In 1984, Para Tech was granted exclusive rights for Parylene dimer, and subsequently introduced this revolutionary material to industrial markets.

Technology Leadership

Para Tech holds eight patents related to Parylene deposition that result in unique process efficiency advantages compared to traditional vacuum deposition coating system designs. These proprietary methods benefit coating service customers as well as on-site users of our coating equipment. Learn more about the Para Tech advantage.
