With an eye on the future of the planet, we accurately grasp the needs of our customers and create materials that are highly valuable and indispensable in modern society. We believe that this is our mission.

The products we handle, such as photoacid generators, are essential for high technological industries such as semiconductor manufacturing, but there is a growing demand for further miniaturization and higher purity in the future. This will lead to the miniaturization and power saving of various products, which will in turn lead to energy conservation and environmental protection. With an eye on the future of the planet, we accurately grasp the needs of our customers and create materials that are highly valuable and indispensable in modern society. We believe that this is our mission.

1966年	Established as “San-Abbott,” a joint venture between Sanyo Chemical Industries, Ltd. and Abbott USA.
1970年	Developed the U-CAT SA Series (DBU salts). Market development began for the products as urethane catalysts and epoxy curing accelerators.
1986年	Overseas parent company changes to Air Products and Chemicals, Inc., and our company name was altered to San-Apro.
1998年	Investigations began regarding technologies and markets for new products to replace DBU. Photo acid generator developed.
2003年	The CPI-100P and 101A photo acid generators (for photocationic polymerization initiations) were introduced to the market. Efforts began to introduce these products to the can paint and optical modeling resin markets.
2007年	The high-activity non-Sb CPI-200K product was developed and efforts began to introduce it into the marketplace.
2010年	The highly i-line sensitive CPI-300 series was developed and entered the electronic materials market.
2016年	The company celebrated its 50th anniversary. Sales of photo acid generators steadily increase, and the business progresses in its transition.
2017年	Parent company changed to Evonik Industries AG.
