Chemical properties:
Dipropylene glycol butyl ether has a high boiling range, slow volatility, light odor, and good solubility in a variety of materials such as water-based latex, plasticizers, acrylic resins, epoxy resins and polyurethane resins.
Main uses:
Dipropylene glycol butyl ether (DPnB) is a colorless, transparent liquid with a slight ether odor and bitterness. It is soluble in water and has good binding force. It has good solubility and binding properties for coating resins and is an excellent film-forming aid. As a commonly used film-forming aid for water-based coatings, dipropylene glycol butyl ether plays a very important role. First of all, it does not improve film-forming properties. DPNB is not hydrophilic and is easy to demulsify in some water-based emulsions, so special attention should be paid to its use. One of the major effects of DPNB is that it can improve the viscosity of water-based coating systems, especially multi-solvent systems. Thickeners have no effect at all. DPNB combined with neutralizers can greatly increase the viscosity of the coating, have good storage properties, and will not sag or bloom when sprayed in dilute form. DPNB can also improve the defoaming property of water-based coatings, which is helpful for defoaming in both production and construction. Dipropylene glycol butyl ether DPnB has high film-forming efficiency and medium-slow volatilization rate, so it can be used in the following aspects:
1) Coatings: One of the most effective film-forming aids for water-based coatings, giving the paint film excellent properties; it can be used as a coagulant for acrylic resins, styrene acrylic resins, and polyvinyl acetate, giving the paint film excellent properties. It is one of the most effective film-forming aids for many water-based coatings.
2) Cleaning agents: Suitable for cleaning agents, especially systems that require extremely low volatilization rates, such as wax removers and floor cleaners. It is a good coupling agent for grease and oil, and can be used as a paint remover and animal fat remover.
3) Other applications: agricultural products, cosmetics, electronic inks, and textiles.
