Overview
2-Propoxyethanol is a glycol ether solvent known for its balanced properties, making it suitable for a variety of industrial applications. It is part of the glycol ether family, which are widely used due to their ability to dissolve both polar and non-polar substances. 2-Propoxyethanol is particularly valued for its moderate evaporation rate and relatively low toxicity compared to other solvents in its class. This compound is commonly used in formulations where a slower evaporation rate is desired, such as in paints, coatings, and cleaning products. Its ability to mix with water and organic solvents enhances its versatility, allowing it to be used in aqueous and solvent-based systems alike.
Physical and Chemical Properties
2-Propoxyethanol is a colorless liquid with a mild, ether-like odor. It has a molecular weight of 104.15 g/mol and a density of 0.91 g/cm³ at 20°C. The compound is miscible with water and most organic solvents, including alcohols, ketones, and hydrocarbons, which makes it highly effective as a solvent. Its boiling point ranges between 150-152°C, and it has a melting point of -90°C. The moderate evaporation rate of 2-propoxyethanol is one of its key advantages, as it allows for better control in applications like coatings and inks, where drying time is critical.
Main Applications
2-Propoxyethanol is widely used in the formulation of paints, coatings, and varnishes due to its ability to dissolve resins and improve flow properties. It is also a common ingredient in industrial and household cleaners, where it acts as a degreaser and solvent for oils and greases. In the printing industry, it is used in ink formulations to adjust drying times and improve print quality. Additionally, 2-propoxyethanol finds applications in the production of adhesives, where its solvency and evaporation rate contribute to strong bonding properties.
Safety and Storage
While 2-propoxyethanol is less toxic than some other glycol ethers, it should still be handled with care. Prolonged skin contact or inhalation can cause irritation, and proper personal protective equipment (PPE) such as gloves and goggles should be used when handling the chemical. Storage should be in a cool, dry, well-ventilated area away from heat sources and open flames. Containers should be tightly sealed to prevent evaporation and contamination. Spills should be cleaned up immediately using absorbent materials, and disposal should comply with local regulations.
B2B Procurement Guide
When procuring 2-propoxyethanol, B2B buyers should prioritize suppliers who adhere to safety and quality standards. Bulk purchases can often reduce costs, but buyers should ensure proper storage facilities are available to maintain the chemical's integrity. It is advisable to request safety data sheets (SDS) and certificates of analysis (CoA) from suppliers to verify purity and compliance with industry standards. Buyers should also consider the logistics of transportation and storage, as improper handling can affect the quality of the product.
