Polyamidoamines are made from the reaction of higher ethylene amine i.e. tetraethylenepentamine with a fatty acid such as Tall Oil Fatty acid. Poly amidoamines are basically mono-adducts of polyamine with TOFA and having higher molecular weight than polyamine and therefore longer reaction rate but Polyamide are bi-adducts with even bigger molecular weight and thus, reflect higher viscosity and also longer pot life. Poly amidoamines are curing agents for ambient temperature applications.
Poly amidoamines form a low viscosity and exhibit good adhesion especially to concrete, corrosion resistance, lower odor and are able to cure under humid conditions.
