Electrostatic thick-coating of conductive surfaces - with lacquer or paint applied at normal or elevated temp.

Electrically conducting surfaces are thickly coated, with air or oven drying, with a 2-component lacquer or paint by continuous electrostatic application at a normal or elevated temp. Preferably the appts. has the lacquer or paint, to be sprayed, continuously mixed; spraying can take place cold or at elevated temp., by heating in the appts. The lacquer or paint is made with no, or little, solvent; the electrical conductivity is regulated, and the thixotropy is increased, at normal or elevated temp. to give a reduction of viscosity; the thick coating does not have to be fired in. The system achieves a uniform colour and avoids the normal wear effects in the pistol used due to the rubbing action of the particulate components being discharged.

IMPROVED METHOD FOR APPLYING PROTECTIVE COVERING TO SURFACES

Coating of surgical devices

The invention provides a method for the coating of a surgical device, wherein the coating is carried out by electrostatic Powder deposition. The device may be a device used in a surgical or diagnostic procedure, including interventional devices as well as implantable devices. Because the coating is applied electrostatically, it is attracted to all parts of the device, not just those parts that are in the 'line of sight' of the spray, as is the case with conventional liquid spray coating. The process allows uniform and reproducible amounts to be deposited and thus drug-eluting coatings can be accurately applied to stents and other surgical devices, resulting in good control over drug release. Furthermore, drug-eluting coats can be applied in a single step, although multiple layers can easily be applied if desired to create a specific drug release profile.
