1429 Soldering Flux
Kester 1429 VOC-Free Organic Water-Soluble Flux is a self-neutralizing type of flux formulation based on research work originally performed at the Battelle Memorial Institute. The unique chemistry of 1429 flux provides for self-neutralization through a time/temperature relationship which results in a residue which is neutral and non-corrosive when properly heated. As with any organic flux, excessive heating can cause the flux to char and decrease both fluxing ability and removability. The surface tension of 1429 flux has been adjusted to promote solder flow, prevent icicling and bridging and obtain a bright soldered surface. As with any Kester flux formulation, 1429 Organic Flux is manufactured under strict quality control requirements for consistent performance and assured reliability.
