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.

Trade names include: Duralon and Rilsan.

Nylon coatings can be engineered with the following attributes:

  • Impact Modified. To improve strength and stiffness.
  • Glass and Carbon Fiber Reinforced. To improve strength, stiffness and dimensional stability at high extrusion temperatures.
  • Glass Fiber & Impact Modified. To improve strength, stiffness, dimensional stability at high extrusion temperatures, and enhanced surface appearance.
  • Mineral Reinforced. To enhance strength, stiffness, and maintain chemical resistance.
  • Glass & Mineral Reinforced. To achieve exceptional balance of mechanical properties with minimal warpage.
  • Flame Retardant. To comply with standards, including: UL94 V0, V2, 5Va, GWFI/GWIT.
  • UV and Heat Stability
  • Color, Anti-Stat, Anti-Microbial. Nylon coatings can be customized to various requirements.

Duralon N6, N66, N12

Duralon is from the family of nylon-based compounds, mainly compounded using Nylon 6, Nylon 66, and Nylon 12 polyamide resin. Duralon compounds are specifically designed for a highly diversified range of injection, blow, extrusion and rotational molding applications.

Variations in formulation allows for compounds with a wide variety of performance attributes, whether it is for high flexibility, impact resistance, stiffness, dimensional stability, tensile strength or enhanced surface finish with excellent processing conditions.

Duralon grades can be engineered for enhanced processing conditions. These nylon coatings can deliver a rich uniform surface appearance even with the addition of reinforced additives such as glass fiber. The end result is lower reject rates, better aesthetics and faster cycle times.

Duralon is used widely for injection molding applications but can also be formulated for extrusion and blow molding. Duralon compounds can be used for many applications such as a replacement for metal parts or car engine components. Exceptional electrical insulation, corrosion resistance and toughness make Duralon a good choice for high load parts in electrical applications such as insulators, switch housings, and cable ties. Another major application of Duralon is power tool housings and sport applications (such as ski bindings and in-line skates). This is because it has excellent fatigue properties and provides high impact and mechanical strength.
