AI Overview
Amine chain extenders, such as aromatic diamines (e.g., Ethacure 100) and polyetheramines (e.g., Jeffamine), are low molecular weight agents used to increase the molecular weight of polymers like polyurethanes and polyureas, enhancing their mechanical strength and thermal stability. They are often used with curing agents, amine catalysts, and silicone surfactants to adjust reactivity and surface properties.
