Anti-spatter agent

Anti-spatter agent is a specialized chemical lubricant or protective coating applied to metal surfaces and welding equipment to prevent the permanent adhesion of weld spatter. During high-temperature welding processes, molten metal droplets known as spatter frequently eject from the weld pool. Without protection, these droplets fuse to the workpiece and the welding torch nozzle, necessitating costly and abrasive post-weld grinding.

The Chemical Mechanism

Anti-spatter agents function by creating a thermally stable, non-stick barrier. Modern industrial agents are generally categorized into two types:

• Solvent-Based: Historically common, offering rapid evaporation but often containing volatile organic compounds (VOCs).

• Water-Based: The contemporary engineering standard; these are non-flammable, biodegradable, and silicone-free, ensuring they do not interfere with subsequent painting or galvanizing processes.
