TOPKLEAN EL 20A
Is a legacy product used for over 15 years by many actors in the electronic & semicon industry to clean solder flux residues after reflow. At INVENTEC we constantly challenge ourselves to make a great product even better. Today we recommend TOPKLEAN EL 80, which not only offers even better performance but also excels from a sustainable point of view.
It is used in co-solvent process to offer a fast & sustainable cleaning process with very high cleaning efficiency. In this process, TOPKLEAN EL 20A is rinsed perfectly with solvents from our PROMOSOLV range.
The co-solvent process has been a game changer for over 15 years now. 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.
