Description

Aziridine, Homopolymer, Reaction Products With 1-Isocyanatooctadecane is a specialized polymeric derivative resulting from the reaction of polyethylenimine with stearyl isocyanate. This compound matters for its unique combination of reactive amine functionality and long hydrophobic alkyl chains, making it a versatile intermediate and performance additive. Industrial users in sectors such as coatings, adhesives, and specialty surfactants need this product for its ability to modify surface properties, enhance adhesion, and act as a reactive site for further chemical synthesis.

Application

• Surface Modifier for Coatings and Inks: Imparts hydrophobic character, improves substrate wetting, and enhances film formation.
• Adhesion Promoter: Used in primer formulations for plastics, metals, and composites to significantly boost bond strength.
• Specialty Surfactant/Emulsifier: Functions as a non-ionic or cationic surfactant in complex formulations for agrochemicals or personal care.
• Crosslinking Agent: Serves as a reactive intermediate in the production of thermosetting resins and polymer networks.
• Textile and Leather Auxiliary: Used as a softening agent, water repellent, or dye-fixing agent in finishing processes.
• Paper Sizing Agent: Enhances water resistance and printability of paper and paperboard products.
• Rheology Modifier: Can influence the viscosity and flow properties of complex fluid systems.
• Corrosion Inhibitor Intermediate: The amine functionality contributes to formulations designed to protect metal surfaces.
