Overview
BEPD (2-Butoxyethyl Propionate) is an organic solvent recognized for its balanced evaporation rate and solvency power. It is commonly used in formulations requiring a slow-evaporating solvent to improve flow and leveling in coatings and inks. Its chemical stability and compatibility with resins make it a preferred choice in industrial applications. BEPD is synthesized through the esterification of propionic acid with butoxyethanol. The resulting compound exhibits low volatility and high solubility in organic materials, making it suitable for prolonged processes where consistent performance is critical.
Physical and Chemical Properties
BEPD is a clear, colorless to pale yellow liquid with a mild odor. It has a density of 0.94 g/cm³ and a boiling point range of 215-217°C, indicating its suitability for high-temperature applications. The solvent is miscible with most organic solvents but shows limited solubility in water. Key chemical properties include its resistance to hydrolysis and oxidation, which contribute to its stability in formulated products. Its slow evaporation rate ensures extended open time in coatings, reducing defects like orange peel or blistering.
Main Applications
BEPD is extensively used in the coatings industry, particularly in automotive and industrial paints, where it enhances gloss and flow properties. Its solvency power makes it ideal for dissolving resins and polymers in ink formulations, ensuring uniform pigment dispersion. In adhesives, BEPD acts as a plasticizer and solvent, improving flexibility and bond strength. It also finds use in industrial cleaners due to its ability to dissolve oils and greases without damaging substrates.
Safety and Storage
While BEPD is considered low-toxicity, proper handling is essential to minimize risks. Use in well-ventilated areas to avoid inhalation of vapors, and wear protective gloves to prevent skin contact. In case of spills, absorb with inert material and dispose of according to local regulations. Store BEPD in tightly sealed containers away from heat and open flames. Ideal storage conditions include a cool, dry environment to maintain chemical integrity over extended periods.
B2B Procurement Guide
When procuring BEPD, prioritize suppliers who provide detailed technical data sheets (TDS) and certificates of analysis (CoA). Verify the CAS number (16484-86-9) to ensure product authenticity. Bulk purchases (e.g., drums or totes) typically offer cost savings, but confirm storage capabilities to prevent degradation. For specialized applications, consult manufacturers about custom formulations or blends. Pricing varies by region and order volume, with reference ranges commonly between $3-$5 per kg. Establish long-term contracts to secure stable supply chains.
