Chemicals

Fry’s Industrial Chemicals consists mainly of soldering fluxes and related chemistries. Fluxes are designed for specific applications to prepare a surface in order to produce a defect-free solder joint. This is accomplished by:

• Removing absorbed gases
• Removing oxide films
• Removing surface tarnishes
• Reducing surface tension of solder and base metal
• Preventing re-oxidation during soldering

There are three major flux types. They are as follows:

Rosin-based and Non-Residue Fluxes (NR)
Rosin based/NR fluxes are generally the least active and least corrosive. They are generally suitable for most electronic type applications and are used in conjunction with a thinner:

Organic Acid Based Flux
Organic Acid fluxes are typically water soluble and are more active than rosin based fluxes. They have non-corrosive residues and are designed for a wide variety of industrial soldering applications.

Inorganic Acid-Based Flux
Inorganic Acid fluxes have the highest activity. Therefore, they are suited for the most difficult to solder applications. These fluxes also have highly corrosive residues.

Fry has designed fluxes for specific soldering needs:

• Heat Exchange Manufacturer
• Cast-on-Strap lead acid battery manufacturer
• Hot Tin Dipping
• Lighting Ballast Manufacturer
• Lamp Manufacturer
• Wire Harness/Lead Tinning
• Stained Glass
• Electronic Soldering – Industrial

Fry has designed fluxes specifically for the needs of this market. These needs brought on the development of the Radsol Heat Exchange fluxes. They offer the following benefits:

The Radsol fluxes are designed specifically to be used in the core bake, header, hand solder, tube mill and heater core applications.

Now with the heat exchange industry changing to lead-free solders, Fry Technology has developed and patented the next generation of heat exchange fluxes. They are:
