Seqens Canada, a subsidiary of the Seqens group, founded in 1989 (formerly St-Jean Photochimie (SJPC) and PCAS Canada), specializes in the synthesis, development and custom manufacturing of high quality materials by managing tight control limits and levels of’ppb scale impurities.

These materials are used by its customers in the formulation of photosensitive resins, anti-reflective products for microelectronics or as semiconductors for the printed electronics industry.

With expertise in project management from R&D to the scale-up stage of new organic compounds and using its skills in process optimization, Seqens Canada helps its clients to accelerate the commercialization of their new products.
