Kester Type RMA Rosin Based Fluxes

Kester rosin fluxes are formulated with high quality purified rosin conforming to LLL-R-626 in specially blended solvent systems. The choice of the proper flux formula is based on the soldering application, desired rosin percentage, type of solvent and the activity level required.
  • Designed for high thermal stability and superior solderability.
  • Complies with MIL-F-14256 Type RMA, and IPC-SF-818 Type MR3C.
  • Higher activity level than standard RMA fluxes, yet still conforms to the MIL-F-14256 Type RMA. Formula 185-15 is recommended for soldering surface mount assemblies.

    Highest level of activity for a Type RMA flux, making it particularly suitable ofr the soldering of multi-layer printed circuit boards. Formulas 186-18 and 186-25 are more suitable for soldering surface mount assemblies.
