Welding Anti-Spatter Agent Cannot Be Painted Over Directly After Use

It is not recommended to apply paint directly after using a Welding anti-spatter agent!

Working Principle:
Before welding, an anti-spatter agent is sprayed on both sides of the weld seam. During welding, the high temperature causes a thin film to form on the surface of the workpiece. This film prevents welding spatter from adhering to the metal surface.

However, the film itself has a certain degree of tackiness, which is essential for isolating the spatter. Without this tackiness, the anti-spatter agent would fail to protect the workpiece.

Both water-based and oil-based anti-spatter agents can leave residues on the surface, and painting directly over these residues may lead to poor paint adhesion or paint peeling.

To address this issue, our company developed THIF-406 Easy-Cleaning Welding Anti-Spatter Agent, which features minimal residue after welding. The tacky film can be easily removed by sandblasting, grinding, or simply wiping with a cloth. If water washing or pickling is performed, removal becomes even easier.

Other models from our company, such as THIF-402, THIF-405, and THIF-408, require additional cleaning processes such as acid pickling or solvent wiping for complete residue removal.

This is a common situation for most anti-spatter products available on the market.
