Beschreibung
Zusammenfassung:	An automated method for depositing colored thermoset resin dots on a metal surface for color coding metal surfaces, such as surfaces on surgical instruments. A liquid one component heat curing thermoset resin is combined with a colored pigment to form a colored liquid thermoset resin. A metal surface is pretreated by spraying with a surface activating agent. Thereafter, one or more drops of the colored thermoset resin are dispensed onto the surface and then heat cured (hardened), thereby forming colored thermoset resin dots. A chemical bond is formed between the colored thermoset resin and the metal, thereby making the thermoset resin dots adhere strongly and permanently to the surface. The method is fully automated with a 3-D colored dot printer and spray dispenser. The colored thermoset resin dots will not flake, peel, or turn up at the edges, thus making them useful for coding surgical instruments. The method does not require any special skill or training.
