How does Orgasol® powder improve abrasion resistance?

Orgasol® powder has a spherical particle shape, which prevents abrasive materials from wearing the surface of coatings and varnishes. Additionally, polyamides have a low coefficient of friction and are well known for their abrasion resistance.

How does Orgasol® powder reduce gloss?

Orgasol® powder can be used as a flattening or matting agent when added to formulations. The presence of Orgasol® powders near the surface will create a light deflection. The gloss reduction is dependent on the ratio of the average particle size (APS) of Orgasol® powders to the dry thickness of the coatings, and also the concentration Orgasol® powders into the formulation.

Can Orgasol® be used to create a texturing effect?

Yes. The "average particle size (APS) of Orgasol® powders dry thickness" ratio, along with the concentrion of Orgasol® powders in the formulation will determine the textured effect. When the coating thickness is smaller than the powder APS, the larger particles produce a bumpy surface and the surface roughness increases. The tight particle size distribution ensures uniformity and consistency of the textured effect.

Can Orgasol® powder be used in UV or EB formulations?

Orgasol® powder can be used in any kind of formulation such as water-based, solvent-borne, 100% solid UV or EB curable systems. In 100% solid UV curable formulations, Orgasol® powder does not impact the viscosity of the formulation while providing low gloss and abrasion resistance.

What resins can be used with Orgasol® powder?

There is no limitation. Orgasol® powders are currently used as additives in a wide variety of resins or binders such as alkyds, polyester, polyurethane, acrylic and epoxy. Orgasol® powders are beneficial in all formulations (water-based, solvent-borne, 100% solid UV or EB curable). However, the best results have been obtained with urethane-based coatings.

Can Orgasol® powder be easiliy dispersed in water-based applications?

Orgasol® powders may be easily dispersed into water with different kind of wetting agents. If your current water-based system already includes wetting agents, simply pre-disperse the Orgasol® powder. If you are using a co-solvent in your water borne system, pre-disperse the Orgasol® powders in the co-solvent and then introduce it into the water-based system.

Can Orgasol® powder improve scuff resistance on low gloss surfaces?

Yes. Adding Orgasol® powders significantly improves resistance, especially when the average particle size (APS) of Orgasol® powders is greater than the film thickness. The larger the APS of the polyamide powder, the more difficult it is to mark the coating surface with a rubber heel and easier it is to clean with a sponge.

Can Orgasol® powder be used to control the coefficient of friction between two surfaces?

Orgasol® powders have a low coefficient of friction and can be used to lower the coefficient of friction between two surfaces. Orgasol® powder improves anti-blocking properties. For example, when added to a polyurethane varnish gasket, it can minimize the coefficient of friction of rubber between rubber and glass, such as between car windows and rubber window seals.
