Product Description

1.  Specification of 2-Hydroxyethyl methacrylate(HEMA)

   Product Name: 2-Hydroxyethyl methacrylate

    Synonym: 2-(Methacryloyloxy)ethanol;2-Hydroxyethyl 2-methylacrylate

    CAS No.: 868-77-9  

    EINECS: 212-782-2

    Abb: HEMA

    MF:C6H10O3

    MW:130.14

Production process: it is produced by esterification reaction of methacrylic acid and ethylene oxide under the effect of catalyst and inhibitor 

Chemical property:  Colorless and transparent liquid, flammable, soluble in water, and soluble in ordinary organic solvents, low viscosity, good attenuant effort, could react in thermal curing and UV curing.

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.)

 

5. Package and transportation of 2-Hydroxyethyl methacrylate(HEMA)

 1) Package: 25kg/drum, 200kg/drum

   Minimum order quantity: no limited

   Production capacity: 

   Delivery date: 3-5 days after the payment confirmed

 

2) storage temperature:15-25

 High temperature, direct sunshine and fire must be avoided when transported
