Description

Laurylpropylenediamine CAS NO 10443-36-4 is a high-purity, long-chain aliphatic diamine derived from lauric acid. This versatile intermediate is valued for its dual amine functionality and hydrophobic tail, enabling it to act as a crucial building block for surfactants, corrosion inhibitors, and epoxy curing agents. It is essential for manufacturers in the lubricant additives, personal care, coatings, and agrochemical sectors seeking to enhance product performance and stability.

Application

• Surfactant & Detergent Intermediate: Key raw material for synthesizing cationic and amphoteric surfactants used in fabric softeners, personal care products, and industrial cleaners.
• Corrosion Inhibitor: Formulated into fuel and lubricant additives to protect metal surfaces in automotive and industrial applications.
• Epoxy Curing Agent: Functions as a hardener for epoxy resins, imparting flexibility and chemical resistance in coatings and adhesives.
• Agrochemical Intermediates: Used in the production of herbicides, fungicides, and pesticide emulsifiers.
• Asphalt Additive: Improves adhesion and moisture resistance in road paving and roofing materials.
• Mineral Flotation Agent: Acts as a collector in the beneficiation of ores.
• Polymer Modification: Serves as a chain extender or cross-linking agent for polyurethanes and nylons.
• Biocide & Preservative Synergist: Enhances the efficacy of preservative systems in industrial fluids and formulations.

Quality Control

Our Laurylpropylenediamine is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, and amine value. Certificates of Analysis (COA) documenting these results are provided and available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Keep away from strong acids and oxidizing agents.
