Reactive polyamides have been a âGo toâ hardener for formulators across a very wide range of industrial and commercial applications and continue to form the backbone of the coating industry. The condensation reaction between the fatty acids and amines is a simple technique used to manufacture reactive polyamides. This helps over come the irritability, volatility and critical loading issues of conventional amines.
Cycloaliphatic polyamines offer high performance of aromatic amines together with the relative ease of mixing of the aliphatic amines. As they offer excellent gloss and color retention and levelling properties, they are a popular choice for formulators.
Phenalkamines are a product of a mannich reaction of cashew nut shell liquid with formaldehyde and various amines. They are relatively more environmentally friendly options to traditional phenolic and mannich curing agents.
