For professionals in the chemical industry, a deep understanding of the properties and sourcing of key raw materials is vital for innovation and efficient production. tert-Butyl Acrylate (CAS 1663-39-4) is a significant acrylate monomer, valued for its contribution to polymer properties and its broad applicability across various industrial sectors. This article provides insights into its chemical characteristics and how to navigate the market to buy this essential compound.

tert-Butyl Acrylate is a colorless liquid characterized by a mild, sweet odor. Chemically, it is an ester of acrylic acid with tert-butyl alcohol. Its molecular formula is C7H12O2, and it has a molecular weight of 128.17 g/mol. A critical property for formulators is its purity, which is often specified at ≥98%. This high purity is essential for achieving controlled polymerization and ensuring the desired performance characteristics in the final product. Its density is around 0.883 g/cm³, and it has a boiling point of approximately 133°C at atmospheric pressure, though it can be distilled at lower temperatures under reduced pressure.

The primary utility of tert-Butyl Acrylate lies in its role as a monomer. When polymerized or copolymerized, it contributes to polymers with a low glass transition temperature (Tg), enhancing their flexibility and improving their performance in cold environments. This makes it a preferred choice for manufacturers in the coatings and adhesives industries. For example, in paints and coatings, it improves flexibility and adhesion, while in adhesives, it boosts tackiness and low-temperature bonding. Businesses looking to buy tert-Butyl Acrylate for these applications need a reliable supplier that guarantees consistent quality and specifications.

The market for tert-Butyl Acrylate is robust, with a significant portion of global supply originating from manufacturers in China. For procurement managers, sourcing from Chinese suppliers often presents an opportunity for cost savings on bulk purchases. It is advisable to request quotes from several reputable manufacturers and suppliers to compare pricing, minimum order quantities, and delivery terms. Understanding the full supply chain, including logistics and import regulations, is part of the procurement process.

Safety is a paramount consideration for tert-Butyl Acrylate, as it is classified as a flammable liquid. Proper handling procedures, storage in well-ventilated areas away from heat and ignition sources, and the use of appropriate personal protective equipment (PPE) are mandatory. Suppliers are expected to provide comprehensive Material Safety Data Sheets (MSDS) detailing all necessary safety precautions. Prioritizing suppliers who demonstrate a strong commitment to safety and quality control is essential for any buyer.

In conclusion, tert-Butyl Acrylate (CAS 1663-39-4) is a high-value monomer with significant industrial applications. Its chemical properties make it a key ingredient for enhancing the performance of polymers in coatings, adhesives, and plastics. For businesses aiming to buy this chemical, focusing on high purity, competitive pricing, and reliable sourcing from established manufacturers, particularly in China, will be key to successful procurement and product development.
