Electronic solder flux producers worldwide depend on the quality, selection and availability of our unique line of organic solder flux activators.
More than 25 years ago, Esprix saw the need to provide a small volume of highly specialized organic compounds for customers formulating electronic solder fluxes or pastes.
Today, Esprix's status as the primary source of unique solder flux activators allows flux formulators to design their materials with the exact balance of properties desired.

Esprix is a pioneer in the development of new, more environmentally-friendly materials. These products are now being used in solder flux formulations that address the need for no-clean, water-clean systems, or lead-free systems. Such materials represent the future for electronic fluxes.

Esprix markets world-class brazing fluxes, important materials used in the global manufacture of automotive heat exchange systems; and solder activators, used in circuit boards and other components in the worldwide electronics and computer industries.

For over a decade, a brazing flux known as FL-7^® has been used in the controlled atmosphere aluminum brazing process to produce heat exchangers primarily for automotive thermal management. In 1994, Esprix recognized the importance of introducing FL-7 to the North American auto industry. During an intense period of regulatory review, Esprix worked closely with the U. S. Environmental Protection Agency, allowing the material to be introduced to this market in 1996.

Esprix's attention to the consistency and purity of the chemical composition and crystal formation of FL-7 has allowed our customers to improve the aluminum brazing process. Esprix's FL-7 formulation has the correct particle size and shape for optimum performance in dry electrostatic systems. In short, it is simply the best flux material available today.
