In search of dreams         

In 2021, the world was unable to escape the disaster of the (global) COVID-19 pandemic. In Japan, the number of infected people has dropped sharply since November, and the food service industry and travel industry are showing signs of revival, but with the discovery of new mutant strains, the situation is still unpredictable. Under such circumstances, telework is becoming more and more popular to prevent infection. One of the issues that came up while advancing telework was the desire to make it easier to digitize documents, remote jobs, and perform virtual communication online. These issues have been solved by various software and hardware, but I think that if we try to promote full-scale efficiency improvement on a larger scale, it will lead to so-called DX in the future.

A digital transformed society is a society in which various activities are made more efficient and convenient by using the power of digital, and are revitalized. I hope that the society will allow humans to focus on human-like activities. And in order to achieve that, I think we need new technologies to support it. In other words, the exchange of huge amounts of data that support the DX society, and the hardware and software that process it. Are they enough resources on hand? Perhaps there will be a need to process unimaginable amounts of data fast and accurately. I am convinced that various innovations will be required for that.

Currently, San-Apro is developing and promoting photo acid generators (PAGs). These PAGs are mainly used in semiconductor manufacturing and microfabrication, but I would like to introduce them for innovation support in a coming era. I believe that the future mission of San-Apro is to create, customize, produce, and supply compounds that meet the front-line user needs to enable dramatic innovation.

We direct the trigger of light.

San-Apro is a fabless company that specializes in research and development of unique catalysts made by full use of organic synthesis technology and has no production plant. Since it is fabless, we believe that it is our major strength to respond to production scales and quantities according to customer needs.
Due to the coronavirus wreck since 2020, it is expected that the difficult situation will continue after 2021.
Even in such rapidly changing situation, we continue to help our customers propose / supply new products to the market.
We want to be a "Serendipity" that can share successful connections with our customers.
We will be a trigger that provides "light" and "passion" to those who visit our new website!
Make full use of our R&D and sales team with our products.
UX Promotion Dept. Manager
Ichiro Wada
In 1966, San-Apro industrialized the organic super-strong base DBU® for the first time in the world, and developed its applications such as urethanization catalysts and epoxy curing accelerators as well as manufacturing intermediates for pharmaceutical raw materials. We have contributed to the development of a wide range of fields as a "special catalyst manufacturer". We have added a new product lineup of photo acid generators (PAG) since 2000, and are expanding our business domain in from heat to light triggered fields.
Based on the seeds of super-strong bases and super-strong acids, we have flexibly responded to changes of the times with a policy of customization based on customer needs. Our foundation (tradition) is a spitiy of "Try It First."
Recently, with the spread of remote work due to the new corona infection, we assume that IoT will further develop. In the future, in order to develop products that respond to various changes, not only the in-company organization but also customers, suppliers, production contractors, university, and specialized institutions, etc. will work together with the challenge spirit of "Try It First". We want to propose new value (product) without fear of failure.
