PA11 thermoplastic powder coating
General information
Rilsan® Fine Powder is a type of thermoplastic polyamide derived 100% from natural sources (Polyamide 11), known for its high durability, developed to provide protective coatings for metal surfaces with high technical requirements, mechanical properties, and paint film protection. Rilsan® Fine Powder coatings can be applied to metal surfaces using various methods including electrostatic spraying, dipping, or specialized equipment (Mini-coater or Rotor-coater). Applications: – Automotive and industrial vehicles – Coating busbars & lithium battery components – Outdoor metal fixtures – Oil and gas pipelines – Medical – Heavy industry – Renewable energy – Linings – Screws
Rilsan® Fine Powder ES/ESY
Product line using electrostatic spraying method (Tribo or Corona)
Electrostatic Powder Coating involves applying charged powder particles onto a metal surface at ambient temperature. The electrostatic charge is generated by passing the powder through a specialized spray device, such as a “corona” or “tribo” spray gun. The charged powder particles are attracted to the grounded surface to create a coating. The coated part is then placed in an oven, where Rilsan® powder melts to form a smooth, non-porous coating layer. Two Rilsan® product lines suitable for this application process are Rilsan® ES and Rilsan® ESY.
Rilsan® Fine Powder T/FB
Product line using embedded method
Fluidized Bed Dipping Process involves immersing a preheated part into a fluidized bed of coating powder suspended by an upward airflow. When Rilsan® PA11 powder comes into contact with the preheated part, it melts and forms a film on the component’s surface. This process yields a uniform thickness, even on complex-shaped parts (covering both interior and exterior surfaces in a single operation). The fluidized bed dipping process is efficient (100% usage efficiency) and simple. All Rilsan® T/FB grades have been specifically developed for this technology, alongside a range of custom-designed primers.
Rilsan® Fine Powder MC/Techline
Product line using Minicoat or Maxicoat method
Arkema has developed the Minicoat Process for coating small objects. Based on this process, the Rilsan® MC and Rilsan® Techline product lines are specifically designed for coating small items, such as components in the lingerie industry. The MC line has an average particle size of around 50 microns, allowing for high yield and precise coating thickness control.
