| environment-friendly solvent | propylene glycol butyl ether is a green environment-friendly advanced solvent, which has a wide range of uses in coatings, cleaning agents, inks, leather and other aspects. It is one of the main components of brake fluid. Propylene glycol ether can also be used for colorful coatings, photosensitive adhesives, PS plate cleaning, printing, electronic chemicals, jet engine fuel additives (waterproofing agents), 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 prepared paint has a smooth, smooth and good fastness. In the process of dye dissolution, it can be used instead of alcoholic solvent, which is a good coupling agent. In the production of ink, propylene glycol ether is used, and some formulas can be changed to water-soluble, which reduces the toxicity of the ink, improves the operating environment, and improves the printing quality. Propylene glycol ether products can be prepared with various types of concentrated cleaning agents with good results. Propylene glycol monobutyl ether is mainly used for heavy scale cleaning agent. It can dissolve and couple oil and grease very well, making it used in household and industrial formulations. Partially water soluble, solubilizing most solvents. The specific applications are as follows: ①Coupling agents and solvents for household and industrial cleaners, grease paint remover, metal cleaners and hard surface cleaners; ②Effective coupling agents and solvents for water-reducing coatings; ③Effective coagulants for water-based latex coatings; ④Active solvents for solvent-based coatings; ⑤ Chemical intermediates for the production of esters, solvents, and plasticizers. |
| application | propylene glycol butyl ether is one of the important products of propylene glycol ether series. it is an excellent solvent and is widely used in coatings, pigments, inks, high-efficiency cleaning agents, printing, leather, electronic chemicals and other industries. |
| propylene glycol butyl ether series | propylene glycol butyl ether series is a promising environment-friendly solvent due to its slight toxicity and pleasant smell. Used in industrial/household detergent 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 coatings, cleaning agents, inks, leather, etc. In the process of dye dissolution, it can be used instead of alcoholic solvent, which is a good coupling agent. In addition, propylene glycol butyl ether series can also be used as film-forming additives for water-based coatings, photosensitive adhesives, PS plate cleaning, printing, electronic chemicals, jet engine fuel additives (waterproofing agents), extractants and high boiling point solvents. |
| use | used as solvent, dispersant or diluent, also used as fuel antifreeze, cleaning agent, extractant, non-ferrous metal concentrator. Intermediates in organic synthesis. |
| production method | 1,2-propylene oxide reacts with n-butanol in the presence of a catalyst, and the reactants are rectified to obtain the finished product. |
