  • Applications

    N-Butyldiethanolamine (CAS 102-79-4) is used primarily as a solvent and processing aid in industrial formulations, including coatings, inks, and cleaning products. It serves as a reactive intermediate for the production of surfactants and emulsifiers (alkyl diethanolamine derivatives) and as a building block in polymer and polyurethane chemistries, where it can function as a curing agent or functional additive. In metalworking fluids and related formulations, it is used to enhance corrosion inhibition and rust-preventive performance. It can also act as a stabilizer and pH adjuster in various systems. Additionally, it may be employed in cleaners and detergents to promote wetting and emulsification, and in some specialty lubricants.
