Orgasol® powders can also be used as texturing agent. Available in a range of particle sizes (from 5 to 60 microns), Orgasol® powders can impart textures from smooth to rough by modifying the ratio of particle size to coating thickness. Thus, the spherical shape of the particles and the very narrow particle size distribution of Orgasol® powders impart very specific regular textures combining pleasant hand touch as well as anti-slip properties.
Shape of Orgasol® and Rilsan® D Polyamide Powders
The Orgasol® and Rilsan® D products will create different types of texture because of the different manufacturing processes used to produce each product range. The Orgasol® products are made by a direct polymerization process with no grinding, yielding a spherical shape. Meanwhile, the Rilsan® D products are polymerized and then ground, producing flakes. The different shapes of the Orgasol® and Rilsan® D materials is evident in the electron micrographs.

Using Orgasol® and Rilsan® D as a Texturing Additive
In order to create texture, the diameter of the Orgasol® or Rilsan® D product chosen must be larger than the dy film thickness (DFT) of the coating. When choosing an appropriately sized Orgasol® product, a “soft touch” or “electronic” texture will result. An appropriately sized Rilsan® D material will yield a “sandy” or “abrasive” texture.

Orgasol® powder in a 100% UV Soft Touch Coating
It is important to remember that the best fit for the Orgasol® and Rilsan® D materials is when improvement in two or more characteristics of the coating is desired. In this example, an Orgasol® product was incorporated into a UV formulation to create a soft touch texture. In addition to creating the desired texture, inclusion of the Orgasol® product helped control gloss and improved stain resistance to coffee, without unfavorably impacting other performance characteristics.
