Description

Dimer Diamine CAS NO 62647-85-2 is a high-purity, long-chain aliphatic diamine derived from dimerized fatty acids. This specialty chemical is valued for its unique combination of flexibility, hydrophobicity, and reactivity, making it a superior building block for high-performance polymers. It is essential for manufacturers in the coatings, adhesives, and advanced materials sectors seeking to enhance product durability and chemical resistance. Its bifunctional nature allows for the creation of polymers with tailored properties.

Application

• Polyamide Resins: Primary monomer for producing thermoplastic and thermoset polyamides used in hot-melt adhesives, powder coatings, and industrial filaments.
• Epoxy Curing Agents: Acts as a flexible curing agent for epoxy resins, improving impact resistance and adhesion in protective coatings and composite materials.
• Corrosion Inhibitors: Used in the formulation of additives for fuels and lubricants, providing excellent metal surface protection.
• Polyurethane Elastomers: Serves as a chain extender or curative to impart flexibility, hydrolysis resistance, and low-temperature performance to polyurethanes.
• Water Treatment Chemicals: Intermediate for synthesizing cationic flocculants and scale inhibitors.
• Surfactants & Lubricants: Key raw material for creating specialty surfactants, emulsifiers, and synthetic lubricants with good stability.
