Polyamide epoxy coatings are based on a curing agent using some sort of reactive polyamide resin. These reactive polyamides are the result of long chain fatty acid dimers reacted with multifunctional amines. These terminal amines have a great molecular distance between them that greatly reduces the vapor pressure of the resin. Polyamide epoxies are normally used in primers for recoatability, flexibility, adhesion, better wetting characteristics, and improved corrosion resistance. They tend to be more resistant to moisture, weather and alkali, but have poor chalk resistance and only moderate acid resistance.
Polyamide Epoxy Paint
The use of epoxy coatings is prevalent in residential, commercial, institutional, industrial, transportation and marine applications. There are different types of curing agents used for different performing characteristics of an epoxy coating. The curing agents react with the epoxy resins and form a cross-linked network that converts the epoxy resin into a full fledged epoxy coating. Choosing one type of epoxy over the other could truly be a conundrum for the unwary.
