(3) Features and functions
1, miscible with water, soluble in common organic solvents.
2, easy to polymerize, polymer glass transition temperature 55 ° C.
3, low viscosity, because it is methacrylate, so the curing rate is slower than HEA.
4. It is less irritating and toxic to the skin than HEA.
5. It is beneficial to improve the adhesion to polar substrates and is a reactive diluent commonly used for solder resists.

 Function and Application of Car Paint Monomer HEMA 868-77-9/2-Hydroxyethyl Methacrylate

1, mainly used for the modification of resins and coatings. Copolymerization with other acrylic monomers can produce acrylic resins with reactive hydroxyl groups in the side chain, which can be esterified and crosslinked, synthesize insoluble resins and improve adhesion. Can be used as a fiber treatment agent.

2, with melamine-formaldehyde (or urea-formaldehyde) resin, epoxy resin, etc., used in the manufacture of two-component coatings.

3, into the high-class car paint, can maintain the specular gloss for a long time. It can also be used as an adhesive for synthetic textiles and synthetic medical polymer materials.

4. The plastics industry is used to make acrylic resin containing reactive hydroxyl groups, which is used as a dehydrating agent for electron microscopy in the electronics industry.
