Amines and isocyanates

In the 1960s, Kumiai Chemical Industry began manufacturing and selling amine curing agents for urethane and epoxy resins.
By utilizing the technology and experience accumulated over the past half century and focusing on developing new products, we have expanded our product lineup to suit the environmental regulations or to target the electronics field to suit various needs.

Environmentally friendly amine curing agent

Our amine curing agents do not contain components that fall under the Ordinance on Prevention of Hazards Due to Specified Chemical Substances(Japan).
Our products are used widely as curing agents for urethane and epoxy resins.
Our products have also been used as raw materials for polymers such as polyamide and polyimide.

Environmentally friendly thermosetting urethane resin system　 " CUA-4 System ”

This is a polyurea resin system developed by our company for elastomer (casting) applications.
Neither of these main agents nor curing agents fall under the regulations of the Law Concerning Special Chemical Substances, the Law Concerning Organic Substances, or the Law Concerning Poisonous and Deleterious Substances(Japan).

Aromatic amine curing agent

They are widely used as curing agents for urethane and epoxy resins. They have also been used as raw materials for polymers such as polyamide and polyimide.

Polyurea resin system “Porea R Series”

This is a two-component mixed-type system of polyurea resin with excellent heat and abrasion resistance developed by our company.

Liquid type curing agent "ML Series”

They are products by diluting individual amine components at room temperature to a liquid state. Custom-made products are available upon request about solvents used, blending ratio, etc.

Isocyanates, others

Isocyanates are widely used as the main raw material for urethane resins.
We also have experience in sales of curing agents for urethane and epoxy resins and various fine chemicals.
