Kester 197 Soldering Flux ROL1 RMA Rosin Flux

Kester 197 Soldering Flux (Mildly Activated Rosin Liquid Flux) is a homogeneous solution composed of high-quality, purified Grade WW rosin dissolved in a specially blended alcohol vehicle. Manufactured by Kester, this formulation incorporates a precise, minimal quantity of an effective activating agent to maximize wetting activity while protecting delicate electronic circuitry.

Technical Features of Kester 197 Soldering Flux

Kester 197 is classified as Type ROL1 flux under the IPC ANSI/J-STD-004 Joint Industry Standard and was QPL approved as Type RMA under the former MIL-F-14256 military specification. Field application has proven this fluxing formulation to be nearly as active in wetting capability as highly activated rosin fluxes, yet the flux and its post-solder residue remain significantly less conductive.

This exceptionally low electrical conductivity is achieved through a minimal concentration of ionic activating agent, as demonstrated by its very high water extract resistivity. The resulting dry rosin residue is non-corrosive, non-conductive, moisture-resistant, and fungus-resistant, actively insulating metal surfaces against atmospheric corrosion.

Key Product Highlights

• Standard Compliance: Classified as Type ROL1 under IPC ANSI/J-STD-004 and formerly QPL approved as Type RMA under MIL-F-14256.
• High Activity Level: Fluxing ability approaches highly activated rosin fluxes while maintaining safe electrical characteristics.
• High Water Extract Resistivity: Low ionic activator concentration ensures minimal conductivity.
• Protective Dry Residue: Non-corrosive, non-conductive, moisture-resistant, fungus-resistant, and protects surfaces from atmospheric degradation.
