Chemical Properties:
  1. Propylene glycol butyl ether series is a promising environmentally friendly solvent due to its slight toxicity and pleasant smell. Used in industrial/household cleaner formulations, it has extremely high safety and is recognized by many developed countries, especially Japan. The evaporation rate is similar to that of ethylene glycol butyl ether, which is a very good substitute for the latter. It has a wide range of uses in chemicalbooks such as coatings, cleaning agents, inks, and leather. In the process of dye dissolution, it can be used to replace alcoholic solvents and is a good coupling agent. In addition, the propylene glycol butyl ether series can also be used as film-forming aids for water-based coatings, photosensitive adhesives, PS plate cleaning, printing, electronic chemicals, jet engine fuel additives (water repellents), extractants and high boiling point solvents.
  2. Used as a solvent, dispersant or diluent, and also used as a fuel antifreeze, cleaning agent, extractant, and non-ferrous metal beneficiation agent. Organic synthesis intermediates.
  3. Colorless and transparent liquid. Melting point -100°C, boiling point 170.1°C, relative density (20/20°C) 0.8843, refractive index (nD20) 1.4174. At 20°C, the water solubility is 6.4% (weight), and the water solubility in the product is 19.2% (weight).
  1. Propasolb is a green and environmentally friendly high-grade solvent, which has a wide range of main uses in coatings, cleaning agents, inks, leather, etc. It is one of the main components of brake fluid. Propylene glycol ether can also be used in colorful coatings, photosensitive adhesives, PS plate cleaning, printing, electronic chemicals, jet engine fuel additives (water repellents), extractants and high boiling point solvents. In the coating industry, it can be used as a solvent for alkyd resin, epoxy resin, acrylic resin, polyester paint, etc. The formulated paint has a smooth, smooth film and good fastness. In the process of dye dissolution, it can be used to replace alcoholic solvents and is a good coupling agent. In the production of ink, propylene glycol ether is used, and some formulations can be changed to water-soluble, so that the toxicity of the ink is reduced, the operating environment is improved, and the printing quality is improved. Propylene glycol ether products can be formulated with various concentrated cleaning agents with good effects. Propylene glycol monobutyl ether is mainly used in heavy-duty cleaners. It can dissolve and couple oils and greases very well, making it used in household and industrial formulations. Partially soluble in water, can solubilize most solvents. The specific applications are as follows:
  2. ①Coupling agents and solvents for household and industrial cleaners, grease paint removers, metal cleaners and hard surface cleaners; ②effective coupling agents and solvents for water-reducing coatings; ③effective coagulants for water-based latex coatings; ④ Active solvent for solvent-based coatings; ⑤ Chemical intermediates for the production of esters, solvents, and plasticizers.
  3. Propylene glycol butyl ether is one of the important products of the propylene glycol ether series. It is an excellent solvent and is widely used in coatings, pigments, inks, high-efficiency cleaning agents, printing, leather and electronic chemicals.
