Amidoamine is a product of the most common amine reaction, 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 a higher molecular weight than polyamine. Therefore a prolonged reaction rate, but 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 are low viscosity and exhibit good adhesion, especially concrete, corrosion resistance, less odor, and can cure under humid conditions.
