Multifunctional coating additives 

The Orgasol® and Rilsan® D products are high-performance, multi-functional coating additives based on polyamide chemistry.  These materials are problem solvers for your waterborne, solvent-borne and UV-coating formulations. The products provide benefits with both in terms of coating performance and processability of the coating.

Orgasol® polyamide powders

Orgasol® is a range of high-performance ultra fine
polyamide powders are used as additives in coatings, ink varnishes, and technical compounds.

Rilsan® D fine powders

Rilsan® D fine powders are a range of high-performance polyamide powders manufactured from a 100% renewable resource (castor plant) and are used as an additive in coatings.

Other properties

Good slip control / Improved cleanability


Poor solvent resistance in some cases

Increase in viscosity

Poor stability / Recoatability issue

The Orgasol® and Rilsan® D products provide a multitude of benefits to coating formulations.  However, the best fit for the use of these materials is when the coating formulator wants to improve two or more aspects of coating performance.  For example, if a formulator is happy with a formulation and just needs to lower the gloss, the formulator should use silica.  However, if the formulator wants to reduce gloss and improve abrasion resistance or reduce gloss without a viscosity spike making the formulation unprocessable, these are ideal situations for the Orgasol® and Rilsan® D technology.  In these types of situations, the use of the Orgasol® or Rilsan® D products will help create a formulation that is both technically and commercially viable.

Orgasol® and Rilsan® D Fine Powders Particle Size Distribution

The Arkema patented polymerization process used to produce Orgasol® ultrafine powder leads to a product with a unique shape and narrow particle size distribution. Made without the grinding step used to manufacture most of other powders, Orgasol® offers spherical particles, in seven sizes from 5 to 60 microns, and a very accurate control of particle size distribution.
The unique Orgasol® process is designed to target accurate and well-controlled fine average particle sizes from 5 to 60 microns. This large product range enables Orgasol® to be incorporated in formulations designed for the can coating market as well as to get unique textured finishes.
