Orgasol® powder: texture and resistance in coil coating
Coil coating is the continuous application of an organic coating on metal (most often aluminium or steel). Since the sheets are formed after coil coating process, coil coaters are constantly looking for improvements in scratch and abrasion resistance of the coating, its flexibility, and innovations in the final surface texture.
Coil coating is used for:
- Building: exterior cladding, partitioning, roofs, garage doors, frames
- Sun protection: roller shutters, venetian blinds
- Interior and exterior machines: shelves and panels, ceilings, air conditioners
- Domestic appliances: refrigerators, washing machines
- Communications:computer housing, telecommunications, audio and video equipments
- Transport: car body panels, bus exterior panels, caravan cladding, road signs
Orgasol® powder imparts the coating with a soft and regular texture and an advantage in applications requiring a very high abrasion resistance, flexibility, and good adhesion. The addition of Orgasol® powder does not affect the weatherability, so it is cladding, roller shutters, tile sheets for residential roofing and garage doors.
Moreover, the wide range of Orgasol® powder average particle size enables coating manufacturers to work with particles from 20 to 60 um depending on the coating thickness and other requirements.
Compared to other competitive products that require a grinding step, the particle size distribution of Orgasol® powder is sharper and more accurately controlled by the manufacturing process.
To be convinced of Orgasol® powder performances, please check the comparison of Orgasol® powder and other common additives in terms of properties benefits for coatings.
Of particular interest to coatings manufacturers is the use of Orgasol® powder to improve the flexibility of the thermosetting polyester resin, especially when other paint additives may reduce coating flexibility. In such cases, ultrafine Orgasol® polyamide powders play the role of a thermoplastic toughening agent in the thermoset polyester matrix. This effect can be optimized by adjusting Orgasol® powder particles size in the coating: the flexibility will be even more improved by smaller size particles.
In terms of process ability, Orgasol® powder is easily dispersed in every kind of formulations, especially in polyurethane and polyester formulations often used in coil coating.
