3. Function and Application of 2-Hydroxyethyl methacrylate(HEMA)
1) UV diluent/Thinner (active monomers)
Directly as active monomer, react in the formula (such as plastic spraying, UV wood coatings, gusset plate paint, vacuum plating paint, paper varnish etc.), have a good dilution effect, and the adhesion is improved
2) Synthesise the raw material
As the (meth) hydroxyl acrylate has hydroxyl, so it could react with many functional groups to synthesise polymer materials:
synthesise thermosetting acrylic resin, and use amino resin to make baked coating;
Synthesise UV resin, such as amino acrylate, polyester acrylates and urethane acrylates.
Synthesise adhesive, fiber finishing agent (UV glue, acrylic adhesive, etc.)
4. Safety of 2-Hydroxyethyl methacrylate(HEMA)
HEMA is small molecular monomers with smell, and irritates skin and eyes, direct touch with skin must be avoided. When constructing, please wear protective gloves and goggles (after splashing in skin, it may become red, burning pain, blistering, peeling. Please daub toothpaste or burn ointment timely, if splashing to the eyes, wash with plenty of water and see the doctor immediately.)
