Resistance of Rilsan® to main chemical products
Rilsan® PA11 features outstanding resistance to oils, hydraulic fluids and fuels, as well as excellent resistance to acids, bases and salts.
The chemical resistance of Rilsan® PA11 coatings is reflected both in high dimensional stability under harsh conditions and in the non-degradation of the polymer matrix, making it the ideal material for highly demanding applications.
