TOPKLEAN EL 20B

Removal of flux residues
Co-solvent process
Evolution of Topklean EL 20A

TOPKLEAN EL 20B is a minor evolution of TOPKLEAN EL 20A and it is especially designed to clean solder flux residues after reflow. While removing almost any solder flux residues, it also leaves no white residues and provides a shiny effect on alloys & metals.

It is used in co-solvent process to offer a fast & sustainable cleaning process with very high cleaning efficiency. In this process, TOPKLEAN EL 20B is rinsed perfectly with solvents from our PROMOSOLV range.

The co-solvent process has been a game changer for over 15 years now and is qualified by several actors in the electronic & semicon industry. It has been developed to replace solvents with a high HSE impact with a more sustainable solution and with equally strong cleaning performance. It particularly stands out when addressing low stand-off components. In contrast, a water-based cleaning system carries the risk that the cleaning chemistry may not be adequately removed due to the significantly higher surface tension of water.
