DMPA is a molecule that has both hydroxyl and carboxyl groups, unique and multi-functional resistance. The free acid group can actively improve the water solubility or water dispersion properties of the resin after neutralizing the alkali. Introducing polar base To improve the adhesion of coatings and the dyeing properties of synthetic fibers; Increase the alkali solubility of the coating. Can be applied to the water The DMPA is a tasteless, free-flowing, white crystalline solid.

DMBA is a new Amyl carboxylic acid with two active hydroxyl methyl groups, so it can be used as synthesis of water-based polymer system which can be widely served in water based polyurethane, polyester and epoxy resin etc.

Description PAPI consists of pure-MDI and polymerized-MDI. It is used in applications such as rigid, semi-rigid, and integral skin foams, as well as coatings, adhesives and elastomers.
