Propylene glycol butyl ether

　　1. Coatings and Inks Industry

　　Solvents and Film-forming Aids:

　　Used in water-based latex paints and industrial anti-corrosion coatings to improve paint fluidity and adhesion, especially suitable for winter construction (lowering the freezing point).

　　Regulates drying speed in printing inks, prevents plate blocking, and enhances ink gloss.

　　Typical Cases:

　　PGBE is added to exterior wall coatings of brands such as Nippon Paint and Dulux to enhance film-forming performance in low-temperature environments.

　　2. Cleaners and Degreasers

　　Metal Surface Treatment:

　　Formulate water-based degreasers to dissolve oils and waxes on metal surfaces (e.g., cleaning of automotive parts); can be used in combination with surfactants.

　　Household Cleaning Products:

　　Added to glass cleaners and kitchen grease cleaners to improve decontamination efficiency, with a mild residual odor.

　　3. Electronics and Industrial Fields

　　Electronic Chemicals:

　　As a photoresist solvent, used in semiconductor wafer cleaning and circuit board etching processes, requiring a purity of ≥99.5% (electronic grade).

　　Fiber and Leather Processing:

　　Acts as a coupling agent in textile printing and dyeing to promote dye penetration; improves coating flexibility in leather finishing agents.
