PA 11 Rilsan Rilsan is a high quality polyamide, produced from a base of ricinoleic acid oil. It is a coating material with anti-abrasive and scratchproof properties, is resistant to practically all chemicals and functions as an electrical insulator. Rilsan therefore enjoys multiple uses as corrosion protection, wear guard, and insulating material in the following areas: Mechanical engineering — production of machinery/apparatus Electronics Foodstuffs industry Medicinal technology Chemical and pharmaceutical industries Mechanical properties high level strength, rigidity and hardness abrasion-...

Electrical properties Very good general electrical properties Dielectric strength >30 kV/mm Electrical properties can be affected by colour pigmentations and the absorption of Rilsan is also available with antistatic properties (spec. resistance < 10%Qcm) Contact with foodstuffs ¢ The vast majority of types of Rilsan carry no harm to health. A few colour pigmentations are unsuitable for use with foodstuffs. White, black and pastel coloured Rilsan coatings are highly weatherproof. Some colour pigmentations are unsuitable for outdoor use. Application The following techniques are possible for the...

Chemical properties of Rilsan Coatings Rilsan coatings display in general a high level of resistance to mineral salts, alkalis, most solvents and organic acids. In the case of mineral acids, phenols and certain chlorified solvents some caution is necessary. Here it is recommended to consult the technical applications department of Arkema, stating the necessary level of resistance to corrosion required in each case: i.e. the type of metal to be protected, temperature and composition of the chemical fluids which are to be stored in these vessels. Practical tests have shown that Rilsan coatings...
