Amidoamines are formed when an alphatic polyamine is reacted with a fatty acid. These curing agents are less volatile and have less irritation potential than polyamines. In general they offer lower viscosities allowing for higher pigment loading and low VOC formulas. Amidoamines also have good adhesion to concrete, yet can be adapted to offer a wide range of working
times while maintaining good cure properties.

Note: Due to the nature of the chemistry, amidoamines do not yield discrete Amine Hydrogen Equivalent Weights. In all cases this number would be represented as a range. The values provided in the table above represent a theoretical calculation from the PHR provided. The PHR would also be best represented by a range and should be determined by the customer based on their formulation and desired properties. The PHR values above are utilized by Cargill for the determination of the gel times reported in the table and on actual product specifications.
