Azo polymerization initiators

An azo polymerization initiator is a compound having an azo group (R-N=N-R'), which decomposes with heat and/or light, and forms carbon radical. The formed carbon radical is excellent in reactivity, and progresses polymerization and halogenation reactions of different types of vinyl monomers.

Photo cationic initiators
(WPI series)

Photo cationic initiators are compounds that generate an acid upon UV irradiation. Since various acids derived from anionic sites are generated, they are used for various polymerization reactions such as epoxy curing. We have a lineup of iodonium-type cationic initiators with substituents such as long-chain alkyl groups, which have high compatibility with resins and low volatility of benzene by-produced after photolysis, resulting in low toxicity. In addition, iodonium salts have high photodegradability, and it is possible to improve sensitivity and extend the wavelength by using sensitizers.

Photo base generators

A photo base generator is a compound which generates organic base such as amines upon irradiation of light in the UV range.
The generated organic base accelerates an anionic UV curing of epoxy resin, sol-gel method, etc.
