General description
2-Isocyanatoethyl methacrylate, belongs to the class of monomers known as isocyanate monomers. The presence of the isocyanate functional group in 2-Isocyanatoethyl methacrylate makes it highly reactive. This reactivity allows it to undergo polymerization and form cross-linked networks for the development of polymers with improved mechanical strength, chemical resistance, and adhesion properties. It is also used as a crosslinker in the manufacture of many resins, in electrodeposition, and adhesives, and as a co-monomer in crosslinked polymer polyolstyrene-acrylic resin, which is used in construction products, such as ceramic tile adhesives, fillers, putties, and elastomeric roof coatings.
Application
2-Isocyanatoethyl methacrylate can be used as:
- A reactive monomer in the synthesis of poly(methyl urethane) acrylate oligomer for UV-curable coatings. By incorporating urethane and acrylate groups into the polymer, it enables the polymer to be utilized in UV-curable coatings, inks, and adhesives.
- An additive in propylene carbonate-based electrolyte to enhance its properties, such as viscosity, conductivity, and stability. This improves the overall performance of the electrolyte and the battery.
- As a modifier in the copolymerization process to prepare a bioprosthetic heart valve, which is used in the application of transcatheter aortic valve replacement.
- A latent cross-linker for adhesive resins and coatings.
