1.It is mainly used for resin and coating modification
2.Used in the manufacture of paint, car paint and primer with resin, polymer resin can be applied to the light, playing board, printing ink, gel (contact lenses) and tinned material coating, transmission electron microscope (TEM) and optical microscope (LM) embedding reagent, samples used for "sensitive antigen sites" of hydration
3.Plastic industry used in the manufacture of containing active hydroxyl acrylic resin
