Description and Uses
Butyl methacrylate (BMA) is the organic compound with the formula C4H9O2CC(CH3)=CH2. A colorless liquid, it is a common monomer for the preparation of methacrylate polymers. It is typically polymerized under free-radical conditions.
Butyl methacrylate is a versatile, plasticizing methacrylate monomer that acts as an important building block in many copolymer compositions. Serving as a base for acrylic resins, BMA provides exceptional weather resistance, high gloss, color retention, and durability. BMA contributes more intermediate glass transition and hardness values, with a glass transition temperature (Tg) of 20 °C.
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.
