Product Introduction:
2-Hydroxyethyl methacrylate (2-HEMA or HEMA) is a monomer used to make the polymer polyhydroxyethyl methacrylate. The polymer is hydrophobic, nonetheless, when the polymer experiences water, it swells due to the hydrophilic side groups of the molecule. epending upon the chemical as well as physical structure of the polymer, it can soaking up 10 to 600% water (about dry weight). As a result of this property, it was one of the first products efficiently used to make adaptable contact lenses.
The chemical formula of 2-hydroxyethyl methacrylate is C6H10O3, where all the three hydroxyl groups are attached to carbon atoms. HEMA is known for its low viscosity and high elasticity, which makes it a good elastomer.
2-Hydroxyethyl methacrylate is a polyhydric alcohol that is used in the manufacture of thermoplastic polymers. Hydroxyethyl methacrylate is a monomer because it does not have an oxygen atom, but it does have an internal carboxyl group.
2-Hydroxyethyl methacrylate can be used to produce flexible plastics and is commonly used for example in injection moulding machines. This compound has been found to have many uses such as coating a variety of materials and is versatile in many ways such as for example for use in plastic moulds.

Product Usage:
2-Hydroxyethyl methacrylate (2-HEMA) is a synthetic resin commonly used in adhesives, coatings and many other industrial applications. It is a common ingredient in linoleum, floor tiles and plastic packaging products. Unlike other known materials, it has unique physical properties.
Hydroxyethyl methacrylate is primarily used for the alteration of coverings and also materials. It can be copolymerized with other acrylic monomers to obtain acrylic resins with energetic hydroxyl groups in the side chains, which can be used for esterification and also cross-linking reactions to enhance and synthesize insoluble materials bond, as well as can be used as fiber therapy agents.
2-Hydroxyethyl methacrylate reacts with melamine-formaldehyde (or urea-formaldehyde) resin, epoxy resin, etc. to make two-component coatings. When added to the paint of deluxe cars, it can maintain the mirror gloss for a long period of time. It can likewise be used as an adhesive for synthetic fabrics and also as a medical polymer monomer.
Made use of as a crosslinking monomer in the manufacture of emulsion-based or solvent-based acrylate adhesives. Because of the visibility of polymerizable plastic bonds and active hydroxyl groups, it is very easy to homopolymerize to create a soft material with excellent gloss, openness and also weather resistance. It is used as a call lens product.
2-Hydroxyethyl methacrylate is likewise utilized in the manufacturing of photosensitive resins, clinical polymer products as well as thermosetting coatings. It can react with melamine formaldehyde resin and also epoxy resin to create two-component coatings for high-end automobiles. It can additionally be made use of as a modifier of material for fiber and also non-woven material processing, as well as material for paper handling.
2-Hydroxyethyl methacrylate is a colorless, volatile liquid that is safe to apply to the skin. It is commonly used as adhesives and sealants, as well as in flat panel displays, medical devices and automotive parts.
2-HEMA, a compound made in the presence of oxygen, has long been used in medicine, plastics and cosmetics. It is an acrylic polymer used to make plastic fibers, coatings, adhesives, paints, and more.
