Corrosion Protection

Product Coating – Rilsan Nylon 11

Most Viking Johnson products are supplied with Rilsan Nylon 11 to ensure full protection against corrosion.

Rilsan Nylon 11 is a thermoplastic polyamide powder coating produced from a renewable raw material of plant origin (Castor Oil).  Applied by dipping in a fluidised bed, it forms a durable protection with excellent resistance to impact, abrasion, weathering, many chemicals and with good thermal stability and flexibility.  Rilsan Nylon 11 provides all the corrosion protection you need for most buried and above ground service applications and eliminates the need for any further protection, such as on-site wrapping. For specific chemical resistance information, please check the chemical resistance chart at the end of the section, or ask for specific recommendations.

Rilsan Nylon 11 is both WRAS and DWI approved, is suitable for use with potable water and has a maximum operating temperature rating of 90°C (195°F) for water service.  It also meets the requirements of WIS 4-52-01 Part 1 and EN 10310.

Site repair of localised surface damage, e.g. through careless handling, is straightforward using the Rilsan Repair brush.
