Description

(Z)-n-9-Octadecenylpropane-1,3-Diamine is a high-purity, unsaturated diamine surfactant and chemical intermediate. This compound is valued for its bifunctional reactivity, offering both primary amine groups and a long-chain olefinic tail, which enables its use in synthesis and surface modification. It is primarily sought by manufacturers in the polymer, textile, and personal care industries for applications requiring cationic functionality or as a building block for specialty chemicals.

Application

• Cationic Surfactant & Conditioner: A key ingredient in fabric softeners, hair conditioners, and personal care formulations, providing excellent softening and antistatic properties.
• Epoxy Curing Agent & Hardener: Functions as a reactive amine hardener for epoxy resin systems, contributing to flexibility and improved chemical resistance in coatings and adhesives.
• Corrosion Inhibitor Intermediate: Used in the synthesis of oilfield chemicals and industrial corrosion inhibitors for metal protection.
• Asphalt Emulsifier: Acts as an emulsifying agent in the production of cationic bitumen emulsions for road construction.
• Mineral Processing Aid: Employed as a collector or modifier in the flotation process for beneficiation of minerals.
• Polymer Modification: Serves as a monomer or chain extender in the production of polyamides, polyurethanes, and other specialty polymers.
• Biocide & Preservative Synergist: Enhances the efficacy of certain biocides and preservatives in industrial fluid systems.
