Application of Propylene Glycol Butyl Ether (PB)
PnB is mainly used as a cleaning agent for the heavy contaminant. It can dissolve coupling oil and grease efficiently and make itself suitable for the formula of household and industrial. Partially soluble in water, PnB can solubilize most solvent with the application as follows: as household and industrial cleanser, remover of grease and paint, coupling agent and solvent of metal and hard surface cleanser; as effective coupling agent and solvent of water-reducing coatings; as effective coagulating agent of water-based emulsion paint; as active solvent of solvent-based paint; as chemical intermediate forester, solvent and plasticizer manufacture.
CAS NO: 29387-86-8
Propylene glycol butyl ether (PNB) is mainly used for heavy-duty cleaners and can dissolve and couple oils and fats extremely well, making it suitable for household and industrial formulations. It is partially soluble in water and soluble in most solvents. Its evaporation rate is similar to that of ethylene glycol butyl ether and is a very good alternative to the latter. It is commonly used with other propylene glycol ethers such as dipropylene glycol methyl ether, propylene glycol n-propyl ether, and dipropylene glycol n-propyl ether. It can be specifically applied as 1. household and industrial cleaners, grease coating removers, metal cleaners and hard surface cleaner coupling agents and solvents; 2 effective coupling agents and solvents for water reducing coatings; 3 water-based latex coating effective coagulants; 4 solvent-based coating active solvents; 5 chemical intermediates in the production of esters, solvents, and plasticizers.
Due to its extremely low toxicity and pleasant odor, it is a very promising environmentally-friendly solvent and widely used in industrial/household cleaner formulations. It is extremely safe and has been well-received by many developed countries, especially Japan. Since its HLB value is close to the mid between water and oil values, there is a lot of development room in paint/ink/cleaner formulations.
PNB is a green and environmentally-friendly high-grade solvent. It has a wide range of uses and applications in paints, cleaners, inks, and leather. In the coating industry, it can be used as a solvent for alkyd resins, epoxy resins, acrylic resins, polyester paints and the like. The paint mixed with it has smooth, flat and fast surface. In the process of dye dissolving, PNB, as a good coupling agent, can be used to replace the alcoholic solvent. In the production of inks, added with PNB, some formulations can be converted to being water-soluble, reducing the toxicity of the ink and improving the operating environment and the printing quality. PNB products can be formulated as good concentrated detergents. In the new brake fluid, its content can be as high as more than 40%, which is one of the main components of the brake fluid. In addition, PNB can also be used for colorful coatings, emulsions, PS plate cleaning, printing, electronic chemicals, jet engine fuel additives (water repellents), extractants, and high-boiling solvents.
