Our coating powders are suitable for processing with electrostatic, tribo and vortex sintering procedures. Electrostatic coating with powder paints is of great economic significance. Ease of handling, the recovery of unused powders and the omission of solvents represent key advantages over wet painting.
Compared with conventional thermosetting powder paints, thermoplastic material can offer significant advantages in many applications. The functional powders of the LUVOCOM® P product group close the gap between simple polyamide coatings and expensive high-performance coating systems based on fluoropolymers.
Individual powder solutions
The production of plastic powders is costly. Industrial plastics are ground mechanically at cryogenic temperatures. Intermolecular bonding forces or electrostatic charges on the small lightweight particles are so dominant as to obstruct their further processing and handling. Special additives thus guarantee their free-flowing properties. The absence of pressure during processing demands a modified melt rheology compared with injection moulding; the polymeric powders are intended to undergo sintering to form a thin, dense film but preferably with their full molecular weight in order to retain their mechanical properties. Finally, surface tensions have to be adjusted to allow the particles to agglomerate in the heat. We master these processes that make our LUVOCOM® P products into specialities.
