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.
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.
Absolutely! Orgasol® powder is compatible with glossy finishes when a small percentage is added to formulations.
Yes, Orgasol® powder combined with silica produces very low gloss (<10).
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.
Orgasol® powder has a good impact on formulation stability. Unlike PTFE powder, the low density of Orgasol® powder prevents it from settling out of the mixture.
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.
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.
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.
Orgasol® powders have excellent chemical resistance, making them compatible with most solvent systems. Simply add the Orgasol® powders at the end of the mixing phase, allowing enough time for the solvent to wet the Orgasol® powders.
Yes, Orgasol® powder is often used for that purpose in sport and industrial floorings. By using a large particle size compared to the coating thickness, a rough texture can be obtained to produce anti-slip and easy-to-clean properties.
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.
The effect on film clarity of clear surfaces depends on the choice of Orgasol® powders used and amount used. Adding up to 15% of Orgasaol® powder does not change the clarity of the clear surface.
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.
