How is agglomerated flux made in relation to bonded flux?

• A. They are made in much the same way as bonded fluxes, but use a ceramic binder requiring higher curing temperatures
• B. They use the same binder as bonded flux but lower curing temperatures
• C. They are only dried but not pelletized
• D. They are created by dissolving flux in water

Answer: (A)

Agglomerated flux differs from bonded flux mainly in the binder and the curing step. They’re formed in a similar way to bonded flux—flux powder is mixed with a binder and formed into granules or pellets. The crucial difference is the binder: agglomerated flux uses a ceramic binder, which creates a more heat-resistant, durable granule. Because ceramic binders need higher heat to cure and harden, the manufacturing involves higher curing temperatures than those used for bonded flux with organic binders. This is what gives agglomerated flux its robustness in welding environments. The other ideas—just drying without pelletizing, dissolving flux in water, or using the same low-temperature curing—don’t reflect how agglomerated flux is actually made.
