Tetraethyleneglycol Monomethyl Ether, with the CAS number 23783 - 42 - 8, is a high - quality chemical product offered at the best price. This product is a clear, colorless liquid with good solubility in water and many organic solvents. Its molecular formula is C₉H₂₀O₅, and it has a molecular weight of approximately 208.25 g/mol. The boiling point of Tetraethyleneglycol Monomethyl Ether is around 276 - 278 °C, and its density is about 1.038 g/cm³ at 20 °C. It has a flash point of 146 °C, which indicates a relatively low flammability risk under normal conditions.
Tetraethyleneglycol Monomethyl Ether has a wide range of applications in various industries. In the paint and coating industry, it serves as a high - boiling - point solvent. It can improve the flow and leveling properties of paints, enhance the adhesion of coatings to substrates, and prevent the formation of defects such as orange peel and pinholes. In the printing ink industry, it is used as a solvent for inks, helping to adjust the viscosity and drying rate of the ink, ensuring clear and sharp printing results. Additionally, it is employed in the textile industry as a dyeing assistant. It can improve the solubility of dyes, promote uniform dyeing, and enhance the color fastness of dyed fabrics.
When using Tetraethyleneglycol Monomethyl Ether, it is necessary to follow certain safety procedures. First, wear appropriate personal protective equipment, including safety glasses, gloves, and a lab coat. In the paint and coating formulation process, add the product slowly into the mixture under stirring conditions to ensure uniform dispersion. The dosage should be determined according to the specific formulation requirements. For example, in a common acrylic paint formulation, the addition amount of Tetraethyleneglycol Monomethyl Ether can be around 5% - 10% of the total formulation. In the printing ink preparation, it can be added during the grinding or mixing stage to adjust the properties of the ink. In the textile dyeing process, it can be added to the dye bath, and the concentration should be adjusted according to the type of fabric and dye used.
Caso 1: Formulación de la pintura
A paint manufacturer was facing issues with the flow and leveling of their water - based acrylic paints. By adding 8% Tetraethyleneglycol Monomethyl Ether to the paint formulation, the paint exhibited improved fluidity. The surface of the painted object became smoother, and the occurrence of defects such as sagging and uneven color was significantly reduced. This led to an increase in customer satisfaction and a reduction in the rework rate.
Caso 2: Producción de tinta de impresión
A printing ink company was struggling with the slow drying rate and poor transferability of their inks for flexographic printing. After incorporating 6% Tetraethyleneglycol Monomethyl Ether into the ink formula, the drying time of the ink was reduced by about 30%. At the same time, the ink transfer efficiency on the printing plate was improved, resulting in clearer and more vivid printed images.
Case 3: Textile Dyeing
A textile dyeing factory was having problems with uneven dyeing of polyester fabrics. By adding 4% Tetraethyleneglycol Monomethyl Ether to the dye bath, the solubility of the disperse dyes was enhanced. The dyes were able to penetrate the fabric fibers more uniformly, resulting in more even coloration and improved color fastness. The rejection rate of dyed fabrics decreased from 10% to 2%.
