Overview
Propyl acrylate is an organic compound classified as an acrylic ester, widely utilized in industrial polymer synthesis. It serves as a monomer in the production of homopolymers and copolymers, contributing to materials with enhanced elasticity and weather resistance. Its chemical reactivity makes it a cornerstone in acrylic-based formulations. First synthesized in the early 20th century, propyl acrylate gained prominence due to its balance of cost-effectiveness and performance in coatings. Today, it is a key raw material for sectors requiring durable finishes, such as automotive paints and architectural coatings.
Physical and Chemical Properties
Propyl acrylate is characterized by a low boiling point (123–124°C) and a faint, pungent odor. Its density of 0.89 g/cm³ ensures easy handling in liquid form, though its volatility necessitates sealed containers during storage. The compound’s solubility profile favors organic solvents like ethanol and acetone, while its miscibility with water is limited. Chemically, the presence of a vinyl group adjacent to a carbonyl moiety renders it highly reactive. It undergoes radical polymerization readily, a property exploited in industrial applications. Stability concerns include susceptibility to heat-induced polymerization, requiring inhibitors like hydroquinone during storage.
Main Applications
In the coatings industry, propyl acrylate is a critical component of water-based and solvent-borne acrylic resins, offering UV resistance and adhesion to substrates like metals and plastics. It is also used in pressure-sensitive adhesives for labels and tapes, where its flexibility improves peel strength. The textile sector employs it as a crosslinking agent for fabric finishes, enhancing wrinkle resistance. Additionally, it serves as an intermediate in specialty chemicals, including lubricant additives and plasticizers. Emerging applications include 3D printing resins, where its fast-curing properties are advantageous.
Safety and Storage
Due to its flammability (flash point: 22°C), propyl acrylate must be stored in fireproof cabinets with proper ventilation. Electrostatic discharge safeguards are essential during transfer. Exposure risks include skin irritation and respiratory tract discomfort; nitrile gloves and fume hoods are recommended during handling. Inhibited grades containing 10–50 ppm MEHQ are standard to prevent spontaneous polymerization. Bulk storage tanks should be nitrogen-purged to minimize oxidation. Spills require immediate containment using absorbents like vermiculite, followed by disposal as hazardous waste.
B2B Procurement Guide
Industrial buyers should prioritize suppliers with ISO 9001 certification and batch-specific CoA (Certificate of Analysis) to ensure consistency in purity (≥98%) and inhibitor content. Drum (200 kg) and IBC tote (1,000 kg) options are common, with discounts for multi-ton orders. Logistics must adhere to hazardous material regulations (e.g., UN 1917 Class 3). Regional pricing varies: North America and Europe typically quote $3.50–$5/kg, while Asian markets may offer rates 10–15% lower. Sample testing for residual monomers is advised before large-scale procurement.
