Polyamide

Definition - What does Polyamide mean?

A polyamide is a curing agent chain of polymers linked molecularly by a -COHN- amine group. It is a key chemical component of corrosion coatings. Polyamide resins are resistant to acidic and alkaline substances that are the primary sources of metallic corrosion-inducing attacks.

Corrosionpedia explains Polyamide

Investigative tests have been performed to examine the impact of polyamide coatings on metal surfaces. Results have found that coatings perform better with various concentrations of polyamide resin, even when in combination with other active ingredients such as zinc, lead, vinyls and polyvinyl chlorides.

Polyamide coating properties are typically evaluated using scanning electron microscopes (SEM), cathodic disbonding, electrochemical impedance spectroscopy (EIS) and salt spray tests.
