Environmentally friendly solvent
Propylene glycol butyl ether is a green and environmentally friendly advanced solvent, which is widely used 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 fuel additives (waterproofing agents), extraction agents and high boiling point solvents, etc. 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 paint film with good Chemicalbook 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 formulas can be changed to water-soluble to reduce the toxicity of the ink, improve the operating environment, and improve 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 in heavy-duty cleaners. It dissolves and couples oils and greases extremely well, making them useful in household and industrial formulations. Partially water soluble, can solubilize most solvents.
The specific applications are as follows:
①Household and industrial cleaners, grease and paint removers, metal cleaners Coupling agents and solvents for hard surface cleaners;
②Effective coupling agent and solvent for water-reducing coatings;
③Effective coagulant for water-based latex coatings;
④Active solvent for solvent-based coatings;
⑤Producing chemical intermediates for esters, solvents, and plasticizers.
Application
Propylene glycol butyl ether is one of the important products in 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 industries.
Propylene glycol butyl ether series
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 is extremely safe and recognized by many developed countries, especially Japan. The evaporation rate is similar to that of ethylene glycol butyl ether, making it a very good substitute for the latter. In coatings and cleaning agents , ink, leather and other chemical books. It can be used to replace alcoholic solvents in the dye dissolution process and is a good coupling agent. In addition, the propylene glycol butyl ether series can also be used as a film-forming agent for water-based coatings. Auxiliaries, photosensitive adhesive, PS plate cleaning, printing, electronic chemicals, jet fuel additives (waterproofing agents), extraction agents and high boiling point solvents, etc.
