Applications:

 

A most popular monomer used for synthesizing both water borne and solvent borne acrylic resins. It supplies primary hydroxyl to acrylic resin which offers fast reaction speed and moderate hardness (Homopolymer Tg 55ºC).

2-HEMA based acrylic resins are widely used in 2KPU coating and heat-curing coatings, like automotive coating, industry coating, protective coating, 

2-HEMA can also be used in synthesizing emulsion for non-woven textile, wall coating and industry coating.

2-HEMA's hydroxyl group can further react with other chemicals, like phosphoric acid, generating new (meth)acrylate structure used in synthesizing acrylic resins.

HEMA also used for radcure coating for wood, plastic. It can offer good adhesion to substrate.
