Butyl acrylate

Buyers must prioritize purity levels, typically requiring a minimum of 99.5%. Key parameters include moisture content (≤0.05%), acidity (calculated as acrylic acid, ≤0.01%), and the color index (APHA ≤10). Additionally, verify the type and concentration of the inhibitor, such as MEHQ (Hydroquinone Monomethyl Ether), which is crucial for preventing premature polymerization during transport and storage.

As a hazardous chemical, Butyl Acrylate must have a comprehensive Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. For the EU market, REACH registration is mandatory. Ensure the supplier complies with ISO 9001 for quality management and ISO 14001 for environmental standards. Packaging must meet UN-certified standards for Class 3 flammable liquids.

Butyl Acrylate is a versatile monomer used extensively in the production of acrylic resins, adhesives, and coatings. It is a core component in water-based paints due to its excellent weather resistance and glass transition temperature (Tg) control. It is also widely used in the textile and leather finishing industries, as well as in the manufacturing of pressure-sensitive adhesives and plastics.

Butyl Acrylate is highly reactive; it must be stored in a cool, well-ventilated warehouse away from direct sunlight and heat sources. The storage temperature should ideally be kept below 35°C. Since the inhibitor requires oxygen to function, the container should not be purged with pure nitrogen; a blanket of air (or nitrogen-oxygen mix) is necessary to maintain stability and prevent runaway polymerization.

Butyl Acrylate is classified as a Class 3 Flammable Liquid (UN 2348). Shipping requires specialized dangerous goods (DG) containers or ISO tanks. You must work with freight forwarders who possess DG handling qualifications. Ensure all labeling follows the Globally Harmonized System (GHS) and that the vessel is equipped for hazardous cargo management.

Utilize Made-in-China.com's Audit Reports to verify the supplier's production capacity and legal status. For financial security, use secured payment terms or Letters of Credit (L/C). It is highly recommended to appoint a third-party inspection agency (like SGS or Intertek) to conduct pre-shipment sampling and testing to ensure the chemical composition matches the agreed specifications.

Prices for Butyl Acrylate are heavily influenced by the cost of raw materials like Acrylic Acid and N-Butanol. Buyers should monitor these upstream markets. Negotiate based on volume-based pricing tiers; for example, purchasing in full ISO tanks typically yields a lower per-ton cost than drums. Consider long-term supply contracts with price adjustment formulas to hedge against sudden market spikes.

The most common risks include inhibitor depletion during long transit times, leading to product degradation, and customs delays due to incorrect HS Code classification (typically 291612). Always confirm the shelf life remaining upon arrival and ensure the supplier provides a loading supervision report to prevent contamination from previous cargoes.
