Propylene glycol butyl ether is a green and environmentally friendly advanced solvent. It has a wide range of uses in coatings, cleaning agents, inks, leather, etc. Main uses. 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 (waterproofing agents), extractants and high boiling point solvents. In the coating industry, it can be used as a solvent for alkyd resins, epoxy resins, acrylic resins, polyester paints, etc. The paint prepared has a smooth, flat and fast paint film. In the process of dye dissolution, it can be used to replace alcohol solvents and is a good coupling agent. In the production of inks, using propylene glycol ether, some Chemicalbook 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 used to prepare various concentrated cleaning agents with good results. Propylene glycol monobutyl ether is mainly used for heavy-duty cleaners. It can dissolve and couple oils and greases very well, making it suitable for household and industrial formulations. It is partially water-soluble and can solubilize most solvents. Specific applications are as follows: ① Coupling agent and solvent for household and industrial cleaners, grease and paint removers, metal cleaners and hard surface cleaners; ② Effective coupling agent and solvent for water-reducing coatings; ③ Effective coagulant for water-based latex coatings; ④ Active solvent for solvent-based coatings; ⑤ Chemical intermediates for the production of esters, solvents and plasticizers.
