This is a specialized treatment we do in-house for achieving optical clarity on polycarbonate (PC) plastic. This method can also be used for repairing minor surface defects, and is ideal for achieving an extremely clear surface on complex geometries or hard to reach areas.
After carefully preparing the part with sanding up to #1500 grit, it is then placed in an atmospherically controlled environment. Weldon 4 gas is used to melt the surface of the plastic at the molecular level, which rapidly reforms with all microscopic scratches blended out.
