Rilsan
Rilsan
Rilsan is a thermoplastic powdercoating made from vege-
table ricinus oil. This oil is extracted from seeds of the rici-
nus 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.
Applications
Rilsan is used for different purposes in
several industries. Kersten Kunststof-
coating applies Rilsan as:
• All-sided corrosion protection for pipe
systems in the potable water industry,
shipbuilding industry, waste water indus-
try, process industry and pipe systems

coating technique, Kersten Kunststof-

structions with a length up to 6 meters • Covering/re-covering of rollers for offset-,

Construction
All constructions should be accessible for
visual inspection, grit blasting, coating and
thickness and pore control. It is also neces-
sary to round off sharp edges with a radius

information please ask for the construction
guideline.
• Quality is inspected after the products
have cooled down. On request the
coating will be certified according to the
Kiwa BRL-K746 quality system.
The coating is finally certified by:

Kersten Kunststofcoating uses this unique
procedure to apply coatings to pipe
systems and other constructions.
The procedure is:
• Check construction (according to the

products are suitable for coating.
• Grit blasting SA 2 / .

Grit blasting
Rilsan for rollers
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 under-
estimated.
Like many manufacturers of printing pres-
ses, 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.
Rollers for printing presses

used rollers. Before we can start covering
