Loctite SF7900 Ceramic Nozzel Spray
SF 7900 Ceramic Shield is a ceramic dry film protective coating for MIG/MAG welding processes. This product protects contact tips and welding nozzles by preventing adhesion of welding spatter. This results in significant longer processing times without cleaning of the welding equipment and reduction of downtimes. The repellent film of SF 7900 Ceramic Shield also protects against adhering spatter on jigs, fixtures or fittings, power cables, sensors, metal components and the jaws of spot welding systems. SF 7900 Ceramic Shield is siliconefree.
TYPICAL CURING PERFORMANCE
Once applied the coating dries by solvent evaporation within 5 to 10 seconds at room temperature. Thicker films need longer drying time. Once the welding process begins, the coating hardens on the equipment surface by the heat generated. This provides optimum spatter repellent properties, especially for these severe operating conditions. Surfaces not subjected to any additonal heat can be used straight after drying.
