Amidoamines result from the reaction of most common amine, i.e., tetraethylenepentamine with a fatty acid such as tall oil fatty acid. Amidoamines are basically mono-adducts of a polyamine with TOFA and having higher molecular weight than polyamine, and therefore longer reaction rate. Still, polyamides are bi-adducts with even bigger molecular weight and thus, reflect higher viscosity and longer pot life. Amidoamines are curing agents for ambient temperature applications. Amidoamines form a low viscosity and exhibit good adhesion, especially concrete, corrosion resistance, lower odor, and can cure under humid conditions.
