Most Nylon (or polyamide) Coatings are tough, semi-crystalline coatings with excellent thermal and chemical resistance. The different type of nylon coatings (Nylon 6, Nylon 66 and Nylon 12) offer a wide range of performance qualities with specific gravity, melting point, and moisture content.
Nylon coatings are one of the most versatile and performance proven engineering thermoplastics. Nylon coatings are hygroscopic which means they absorb moisture from their air. This absorption continues until equilibrium is reached (generally 2.4% moisture for unfilled Nylon 6 at 50% relative humidity). In general, the impact resistance and flexibility of nylon increases as nylon takes on moisture, while tensile strength and stiffness decrease. The level of moisture absorbed is dependent on temperature and humidity while the rate is also influenced by crystallinity and part thickness. Preconditioning can be adopted to ensure parts achieve ultimate physical properties before being placed in service.
Industrial nylon coatings provide good resistance to most chemicals including hydrocarbons. Because nylon is a condensation polymer, however, it can be attacked by strong acids, alcohols and alkalis. Because of their high melting point, nylon coatings can be used in high temperature environments. Heat stabilized systems allow sustained performance at high temperatures.
