About Thermal
Acid Generators(Function Map)

What is a thermal acid generator?

It is an onium salt type thermal acid generator.
They are used in thermo-cationic curing adhesives and coatings in the electronic and optical materials fields. We are developing not only highly active but also our original products with higher functionality.
