Therefore, it has been widely used for various purposes.
- the two-component urethane coating composition used as a solvent-based paint is desired to be water-based due to the increase in global environmental protection.
- polyisocyanate used as a curing agent is difficult to disperse in water and easily reacts with water, and carbon dioxide is generated by the reaction. For this reason, development of polyisocyanates having emulsifying properties and suppressing the reaction between isocyanate groups and water even in a water-dispersed state is underway.
