Sigma Technologies began its life in 1985 as a spin-off of General Electric. The company has been a leader in designing and developing high-energy density capacitors for the consumer electronics industry. Dr. Angelo Yializis eventually acquired the company in 1992. Since then, Sigma has dedicated itself to using its experience and expertise in surface treatment and coating technologies to create great products for market/application areas that include but are not limited to, energy storage, fibrous and porous materials, heat management products, barrier films, and performance and effect pigments.
