Detergent coolant FC-1004

high-performancetransparenteco-friendly

Product Overview
FC-1004 is a water-based silicon wafer cutting fluid developed and produced by Gaoce for multi-wire diamond slicing processes. It is circulated and sprayed into the slicing zone to provide lubrication and cooling, to flush and disperse si-kerf particles, and to stabilize cutting conditions. In production, FC-1004 helps increase overall slice yield (notably A-grade wafer yield), reduce diamond wire breakage, and improve flatness (TTV) and saw-mark performance while remaining safe and environmentally compliant (RoHS, REACH).
