Summary

Propoxylated N-tallow-1.3-diaminopropane is a versatile polyetheramine derived from tallow fatty acids and propylene oxide. Its dual amine functionality and adjustable EO/PO chain length make it valuable in coatings, lubricants, and surfactants, offering excellent emulsification, corrosion inhibition, and curing properties.
