Opis

Opis ogólny

2-Ethylhexyl methacrylate(EHMA) is a methacrylate ester monomer with low volatility and excellent adhesion to a wide range of substrates. This monomer enhances the flexibility, impact resistance, and toughness of polymers when used in copolymerization. It has good resistance to weathering and helps to enhance the durability and long-term performance of coatings. These copolymers and coatings are applied in the fields of contact lenses, dental restorative materials, and 3D printing.

Zastosowanie

-Ethylhexyl methacrylate can be used:

• As a monomer to prepare poly(2-phenoxyethyl methacrylate-co-2-phenoxyethyl acrylate-co-2-ethylhexyl methacrylate) (PPPE) intraocular lenses used in cataract treatment. Polymers with 2% 2-ethylhexyl methacrylate are foldable and showed excellent optical and thermomechanical properties.
• To prepare copolymer for the surface modification of dental composite resins to control plaque formation. EHMA imparts water resistance and antifouling properties of dental resins.
• As an internal plasticizer to prepare photo-crosslinked shape memory polymer films used as a photoprintable resins in stereolithography.
• As a precursor to synthesize hydrogels for fabricating contact lenseswith flexibility, permeability, and comfort.
