Weld spatter develops during any kind of welding, whether MIG/MAG welding, spot welding, laser welding, or MIG brazing. In practical application, even optimised procedures cannot fully exclude weld spatter, for instance as part of final runs, in constrained positions or in the event of special material combination.

Weld spatter that has burnt into the material requires intensive reworking, reduces the quality and hence incurs increased costs. Effective protection is consequently required to guarantee effective production.

In addition to protection against weld spatter, process safety is a prominent requirement and can be achieved through optimum weld seams, optimum cleaning and coating. User safety here is equally important, in particular during manual welding work. And last but not least, requirement of environmental compatibility gains greater importance over the last decades.

The objective is reliable protection against adhering weld spatter without causing any side effects.


Workpiece surfaces:
High-quality surfaces free of weld spatter are maintained to prevent reworking. Ideal preparation for any conventional coating methods.

Maintains the precision of limit stops and clamps, prevents sensor faults, considerably reduces cleaning costs, increases the service life.

Tools (MAG welding gun, bolt welding gun, etc.):
Ensures their optimum function, reduces cleaning costs, increases the service life and boosts productivity.


A thin layer of PROTEC Bio anti-spatter fluid is applied to the protected surfaces prior to welding or cutting.

We recommend manually spraying the fluid using PROTEC accessories and spraying equipment. A thin, sealed coat provides sufficient protection against weld spatter.

PROTEC CE15L+ is suitable for welding when wet — even in the event of product deposits.


PROTEC safeguards processes and ensures user safety:

  • Ideally suitable for welding over, no formation of pores
  • Maximum protection against weld spatter, no residue
  • Can be removed without leaving residue as part of a standard process, suitable for immersion (pH-neutral)
  • Suitable for all conventional coating methods (cataphoresis, powder-coating, painting – also using special paints, electroplating, galvanising, enamelling, etc.)
  • Safe and sustainable: non-flammable, biodegradable, renewable raw materials
  • Formation of weld spatter MIG/MAg
  • Clean weld seam, free of weld spatter
  • Welding protection in metal construction
  • Safety and sustainability
