Uses
Monomer for resins, solvent coatings, adhe- sives, oil additives; emulsions for textiles, leather, and paper finishing.
n-Butyl methacrylate is used as a monomer for resins, solvent coatings, adhesives, oil additives, emulsions for textiles, leather, and paper finishing and in the manufacture of contact lenses.
n-Butyl methacrylate is also used in dental resins, oil dispersible pesticides, and acrylic surface coatings and as copolymers, for example, in paraffin embedding media.
manufacture of methacrylic resins, solvent coatings, adhesives, oil additives; emulsions for textiles, leather and paper finishing; cross-linking methacrylic monomer for use in dental composite materials, artificial nails, etc.
n-Butyl methacrylate can be used in the production of organic glass, synthetic resins, rubber and varnish, can also be used for textile finishing, can also be used in adhesives and as a polymer plasticizer for harder resins.
Production Methods
n-Butyl methacrylate is produced by the reaction of methacrylic acid or methyl methacrylate with butanol.
