Rilsan® fine powder coatings are bio-based thermoplastic powders that are renewably sourced. These fine powders are derived from castor oil and made from a polymer known as polyamide 11 (PA11). Coatings derived from polyamide 11 are highly durable, long lasting, and resistant to abrasions, chemicals, and impact. They are also nontoxic, highly flexible, and offer a smooth surface with low moisture absorption. This combination of properties makes Rilsan® fine powder coatings from Arkema an ideal material for coating applications found in the medical field.
Rilsan® fine powder coatings are thermoplastic powder, which means no chemical reaction takes place during the application process. Any changes observed are merely physical changes of state. Conversely, a thermosetting coating is a coating application that involves a chemical reaction. This process requires optimizing the application conditions to achieve the desired coating performance.
Rilsan® fine powder coatings are lightweight polymer powder coatings that exhibit a tensile modulus of 18.5 GPa. This tensile modulus value allows Rilsan® powder coatings to be a phenomenal replacement for metals in the production of demanding surgical tools.
