Monomer butyl acrylate

Buyers must prioritize a purity level of ≥99.5% to ensure optimal polymerization. Key parameters include moisture content (≤0.05%), acidity (calculated as acrylic acid ≤0.01%), and the color index (typically ≤10 Hazen). It is critical to confirm the type and concentration of the inhibitor (usually MEHQ at 10-20 ppm), as this prevents premature polymerization during transport and storage.

As a hazardous chemical, Butyl Acrylate must have a comprehensive Material Safety Data Sheet (MSDS/SDS) compliant with GHS standards. For international trade, ensure the supplier provides a Certificate of Analysis (COA) for every batch. Depending on the destination, compliance with REACH (EU) or TSCA (USA) is essential. The product must be classified under UN Number 2348 (Class 3 Flammable Liquid) for shipping.

Butyl Acrylate is a versatile monomer primarily used in the production of acrylic resins, adhesives, and surface coatings. It is a core component in water-based paints due to its excellent weather resistance and low-temperature flexibility. Additionally, it is widely utilized in the textile industry for fiber treatment and in the paper industry for high-quality coatings.

Butyl Acrylate is highly reactive; therefore, it must be stored in a cool, well-ventilated warehouse away from direct sunlight and heat sources. The storage temperature should ideally be below 25°C. Because it requires oxygen to remain stable (due to the MEHQ inhibitor), it should never be stored under a pure nitrogen blanket; a dry air headspace is necessary to prevent spontaneous polymerization.

The primary risk is accidental polymerization caused by high temperatures during transit, especially when crossing tropical zones. Buyers should insist on temperature-controlled containers (reefers) or ensure the inhibitor levels are sufficient for the duration of the voyage. Additionally, ensure the supplier uses UN-approved packaging, such as ISO tanks or specialized steel drums, to prevent leakage and regulatory fines.

Look for Audited Suppliers who have undergone on-site inspections by third-party agencies like SGS or Intertek. Check for ISO 9001 (Quality Management) and ISO 14001 (Environmental Management) certifications. Review the supplier's export history and buyer feedback specifically regarding chemical stability and delivery timelines to mitigate the risk of receiving sub-standard industrial grade material.

Chemical prices are often tied to upstream raw material costs (like propylene and n-butanol). Negotiate based on formula-based pricing or secure long-term contracts to hedge against market volatility. Request volume-based discounts; for instance, purchasing in Full Container Loads (FCL) or ISO Tanks can significantly reduce the per-unit logistics cost compared to LCL shipments.

Utilize secure payment terms such as Letters of Credit (L/C) or Trade Assurance services provided by platforms like Made-in-China.com. Always mandate a pre-shipment inspection (PSI) by a reputable third party to verify the purity and weight of the cargo before the final balance is paid. This ensures the goods loaded match the specifications in the contract.
