Using thin films and surface functionalization to make great products.
Sigma Technologies began its life in 1985 as a spin-off of General Electric. The company had been a leader in the design and development of high energy density capacitors for the consumer electronics industry. The company was eventually acquired by Dr. Angelo Yializis 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.
