Resin crosslinking agents and corrosion inhibitors

These agents are used as latent curing agents for epoxies in product categories such as paint and adhesives and as crosslinking agents for acrylic emulsions containing ketone groups. Post-curing properties can be controlled by changing the hydrazide compound used. 
Due to hydrazine’s reduction properties, these agents are used as metal reductants and chelate agents in semiconductor and other applications.

Solution

Epoxy resin curing agent

The agent has high one-component storage stability and its post-curing properties can be controlled by changing the curing agent selected.

Acrylic resin crosslinking agent

The crosslinking agent for acrylic paint helps increase coating strength and enables crosslinking when drying at room temperature.

Corrosion inhibitors

Due to hydrazine’s superior reduction properties, corrosion inhibitors are used as metal reductants and chelate agents in semiconductor and other applications.

Applications

Automobile structural adhesives, adhesives for electronic materials and powder paints (epoxies)

These agents have high one-component storage stability and their post-curing properties can be controlled by changing the curing agent selected.

Aqueous acrylic paints

The DAAM/ADH crosslinking system can retain its emulsion stability for a long time.The polymers generated by DAAM/ADH can be expected to enhance the membrane properties of paints.

Corrosion inhibitors

Corrosion inhibitors are used as additives in chemicals used in the process of manufacturing electronic components, such as CMP slurries, semiconductor detergents and solders.

Acroad

We develop and sell special organic chemicals for various rubber compounds by utilizing our organic synthesis technologies, including hydrazine derivatives. In particular, we sell special organic chemicals that can improve the fuel efficiency and durability of automobile tires. Tires are important components that contribute to vehicle safety, environmental friendliness, and comfort. The performance of these tires is largely dependent on the properties of the rubber materials used. The world's first original compounds developed by Otsuka Chemical are used in rubber materials for high-performance tires. These compounds are present in trace amounts in rubber materials, so they are by no means conspicuous, but they make a significant contribution to today's mobility society. In particular, the chemical technology used in fuel-efficient tires, which improves the fuel efficiency of cars, contributes to the reduction of environmental impact, which also leads to the reduction of global carbon dioxide emissions.
