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.

High performance polymerization inhibitors

Polymerization inhibitors are reagents which are used to prevent undesirable polymerization by light or heat. Conventional polymerization inhibitors, such as hydroquinone, are at a disadvantage because they cannot prevent polymerization under certain conditions. By contrast, high-performance polymerization inhibitors Q-1300 and Q-1301 show a strong polymerization inhibiting effect when purifying or storing highly reactive monomers regardless of conditions. Since Q-1300 is water-soluble, and Q-1301 is oil-soluble, these are applicable for different monomers.

Resin modification agents

We have various additives for plastics, synthetic resins and lubricants. Cross-linking agents, polymerization accelerators and reactive antioxidants, to name a few.

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.

Materials for Water-based curing
