Polymer-related chemicals

Polymer materials that support living in any scene

Polymer materials are closely related to living, such as paints, containers, and disposable diapers. We have a large selection of azo polymerization initiators required for polymer production, and also offer a wide range of polymer materials such as photoinitiators, polymerization inhibitors and resin modifiers.

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, such as various cross-linking agents, polymerization accelerators and reactive antioxidants.

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.

UV-Curing Thermally Conductive Insulation Coating Agent (WTCR Series)

WTCR series is a UV-curable thermally conductive insulation composition. An insulating film with high thermal conductivity can be easily formed in a short time by UV-irradiation. As for the thermally conductive cured compositions of paint type, the limit of thermal conductivity is at most about 2W/mk. Meanwhile, thermal conductivity of WTCR-N001 reaches 5W/mk. It can be used for manufacturing aluminum or copper substrate owing to high adhesion to metals. It can maintain its insulation even in harsh environments. It can perform negative patterning with the feature that the UV-irradiated surface is cured.
