Vapor polishing of polycarbonate is a quick process that must be completed in a strictly controlled environment. Active carbon masks are essential for all personnel involved. The extremely toxic solvent gas is only in contact with the surface of the polycarbonate for one to two seconds, and the effect is instantaneous. At Ivy Prototype, there are three people involved in every vapor polishing procedure:
– Weldon kettle manager
– Painter – Part Handling
– Safety inspector, observing from outside the room
During the plastic polishing process, the specially equipped room will fill from the floor up with Weldon gas. After vapor polishing is complete, the room is purged of all solvent using high power extraction fans.
