Rilsan

General

Ricinus Communis

Rilsan is a thermoplastic powdercoating made from vegetable ricinus oil. This oil is extracted from seeds of the ricinus communis plant cultivated in South-America, India and elsewhere. The plant is harvested several times a year depending on the climate. The seeds of the ricinus communis contain approximately 45% oil. This oil is used as the basis for a monomer. Through polymerisation, Arkema, France, produced the polymer, nylon 11, which Arkema has called Rilsan.

Application

Rilsan is used for different purposes in several industries. Kersten Kunststofcoating applies Rilsan as:

• All-sided corrosion protection for pipe systems in the potable water industry, shipbuilding industry, waste water industry, process industry and pipe systems for cooling water. Using a unique dipcoating technique, Kersten Kunststofcoating applies Rilsan on pipes and constructions with a length up to 6 meters and a diameter of approximately 1500 mm.
• Covering/re-covering of rollers for offset-,offset rotation and other printing-presses.

Potable water installation Symons

Rilsan for piping

Dipcoating in a fluidised bed allows an all-sided pore-free uniform coating with a thickness of 0.3 - 0.4 mm. to be applied in a single procedure. This procedure results in application of a uniform corrosionprotection, including at places difficult to reach.

Properties and Benefits

The most important properties and benefits of Rilsan are:

• Chemical very resistant.
• Flexible and tough.
• Smooth and pore-free.
• Free of solvents.
• Weather resistant.
• Certified by Kiwa, Wics, DVGW, etc. for potable water applications.
• After cooling down and quality control, coated products are immediately ready for use without losing time through drying.
• Durable.
• Maintenance-free for the life of your installation.
• Pipe spools are ready for use when they arrive at the construction site.

Construction

All constructions should be accessible for visual inspection, grit blasting, coating and thickness and pore control. It is also necessary to round off sharp edges with a radius of 3 mm. All parts should be totally welded without pores, polished and welding drops should be removed. The holes for the bolts in flanges should be sized 2 mm. larger in diameter if corrosionprotection is required.

Rilsan for printing rollers

Rollers for printing presses

The quality of printing matter depends very much on the right distribution and transport of printing ink. The quality of the covering on the printing rollers is a very important factor that should not be underestimated.
Like many manufacturers of printing presses, we recommend Rilsan because it has excellent resistance to chemical influences of printing ink. The absorption of water and ink is very low and the surface is very smooth and durable.

Kersten Kunststofcoating covers new and used rollers. Before we can start covering used rollers, the old layer is removed very carefully. On request we check and if necessary precision-repair the shafts and bearing chambers of the rollers. 
Rilsan is applied with an over-measure on the rollers. The Rilsan layer is then mechanically finished and if necessary profiled, depending on the function of the roller.
