PA-11 (polyamide 11) coatings are high-performance, bioplastic coatings derived from castor oil, known for their excellent chemical resistance, flexibility, and low moisture absorption, making them ideal for use in harsh environments.
Here are some key features and applications of PA-11 coatings:
- Chemical Resistance: PA-11 coatings offer outstanding resistance to a wide range of chemicals, including hydrocarbons, acids, and bases12.
- Flexibility: These coatings maintain flexibility even at low temperatures, making them suitable for dynamic applications12.
- Low Moisture Absorption: PA-11 has low water absorption compared to other polyamides, which enhances its dimensional stability and performance in humid environments12.
- Temperature Performance: They can withstand a broad range of temperatures, from -40°C to +130°C, without losing their properties13.
- Renewable Source: Being derived from castor oil, PA-11 is a more sustainable option compared to petroleum-based polymers13.
Applications:
- Automotive Industry: PA-11 is used in fuel lines, hydraulic hoses, and air brake tubing due to its chemical resistance and flexibility
- Oil and Gas: It is applied in umbilical hoses and other components exposed to harsh chemical environments
- Medical Devices: PA-11 is used in catheters and other medical tubing for its biocompatibility and low moisture absorption
- Electronics: Employed in wire sheathing and other components requiring electrical insulation and chemical resistance
- Industrial Equipment: Used in coatings for metal parts to protect against corrosion and chemical attack
- Street Furniture: Rilsan coatings are applied to benches, bike racks, and other outdoor furniture to protect against corrosion and wear, ensuring long-lasting performance even in harsh weather conditions
- Architectural Elements: In architecture, Rilsan is used to coat metal components such as railings, facades, and structural elements, providing a durable and aesthetically pleasing finish that resists UV radiation and environmental degradation
