Uses
It is a good crosslinking agent and hydrophilic agent, or used to produce water-based high molecule system, is widely used in water soluble PU system, polyester resin and epoxy ester. With good solubility, it also is widely used in coating of water soluble PU system, adhesive and leather coating agent.. It will become a new kind of environment-friendly substitute of 2,2-Bis(hydroxymethyl)propionic acid.
