Make your soldering easier with a Flux SK10 spray

Advantages/ Features:

  1. flux - an efficient agent to improve solderability
  2. wide possibilities of usage on a PCB and any other joints
  3. also protects from corrosion
  4. in a dry environment can be left on a PCB as a protective layer
  5. filled by an environmentally friendly gas (CO2)
  6. after usage it´s not necessary to clean a nozzle by spraying “upside down”
  7. available in spray or in 1l/ 5l bulk


A flux in a spray from company Kontakt Chemie is a very useful helper for development and production.

Everyone, who´ve ever tried to solder without a flux and then with a flux, probably has seen a big difference in solder spreading and in a resulting joint quality. This effect is very visible on a PCB with bare copper tracks without any surface treatment (for example at DIY production of prototypes) but there´s also a significant difference at boards with a surface treated by tin (HAL) or by gold (Flash, chemical gold,..).

Maybe you have a question, whether it makes sense to add a flux when it already is in a solder wire? Naturally, fluxes in soldering wires are of a high quality and producers of solders (Stannol, Koki, Multicore,...) try hard to reach uniform releasing at soldering and to show a minimum spatter. Mainly at soldering of small joints this spatter often causes, that a flux won´t get to a solder pad, what significantly embarrasses solderability. The charm of a flux is based on the fact, that it is directly on a solder pad and in the desired thickness, which can be influenced by application.

Especially at soldering of SMT components it´s often even impossible to solder by a method “solder wire in one hand, soldering tool in another”, because we usually need one hand to hold a component in tweezers and moreover - often even a 0.5mm solder wire is too thick to precisely dose a solder directly to a small component in for example an 0402 package. That´s why we usually solder SMT components by a method of taking a little bit of solder on a soldering tip and then applying to a component. But here´s a problem, that a flux won´t survive this a few seconds long “journey” but it will degrade by evaporation, oxidation,… In contrast a flux applied directly to a PCB will replace a missing flux from a solder wire and the difference in spreading of a solder is really huge.

FLUX SK 10 (originally called also a LOTLACK SK10) is based on the natural rosin (colophony) and after application it creates a thin layer. This layer makes soldering significantly easier and at the same time it protects from corrosion. That´s why the FLUX SK 10 has wide possibilities of usage as an agent for temporary protection and significant improvement of solderability of PCBs, various contacts, cable assemblies, terminals of batteries,…

A big advantage is, that in a dry environment the FLUX SK 10 can be left on a PCB as a final protective layer. However in a humid environment it undergoes hydrolysis and degrades. In such environment, it´s better to use Plastik 70, Urethan 71 or Silisol 73.

On this place there was a sontest with a contest question:
What´s the recommended drying time after application of FLUX SK 10?

Correct answer was:
30 min.
