Nylon is an exceptionally hardwearing coating that looks like powder coating but is actually a high molecular weight thermoplastic polymer, which is melted on. It provides superior abrasion, and wear/impact resistance when compared to typical polyester powder coating.

Nylon can adhere to most substrates including most metals, steel (carbon, stainless, chrome plated, galvanized), aluminium (sheet, bar, or rod, many alloys, foil, anodized or chromate treated), copper, brass, bronze, red brass, and other alloys.

The Nylon coating is generally much thicker than conventional powder coating finishes (~ 200 microns). Whilst the initial cost of nylon may be greater, the extra cost is recovered many times over by savings in maintenance and replacement costs.

Benefits  of Nylon Coating

There are many benefits of Nylon coatings, these include:

  • Manufactured from renewable resources.
  • Non-toxic.
  • Excellent wear characteristics including outstanding abrasion resistance, very high impact resistance, and a very low friction coefficient.
  • Good resistance to weathering.
  • Good chemical resistance especially to solvents.
  • Good corrosion resistance.
  • Good thermal insulation, ideal for warm to touch applications.
  • Excellent flexibility at low temperatures
  • High vibration absorbing capacity.
  • Smooth low friction surface, and
  • Low moisture pickup.

Rilsan® Nylon Coating

Peratex uses Rilsan Polyamide 11 manufactured by the Arkema Corporation. Rilsan Nylon coatings are popular because they combine strong performance in a number of critical properties, making them an excellent choice for parts with complex functional needs.
