Brazebinder is a viscous 'gel' type hydrocarbon based product, which is used
as a carrier for mixing with braze alloy powders and fluxes to make an
easily dispensable paste. Brazebinder provides the following advantages over
other carriers (primarily water based):
- Brazebinder is very viscous so there is no settling of the metal
powder or flux, thus the resulting paste is very homogeneous.
- It is very slippery, hence can be easily dispensed through automatic
paste dispensers or syringes to make a bead at the joint edges.
- It is non-reactive with flux or metal powder.
- It is clean burning and virtually leaves no residue.
- It is economical, only a small amount of Brazebinder need to mixed
with metal powder or metal powder plus flux combination.
Applications of Brazebinder
- Steel Brazing: The Brazebinder is mixed with Copper powder to
make a paste. Then this paste is applied through syringes or automatic
paste dispensing machines in a bead form (about 1 mm diameter). This
brazing is done in cracked ammonia or Hydrogen atmosphere.
- Copper Brazing: Brazebinder is mixed with Cu-P powder and
braze Cu (mainly radiators) in belt furnace.
- Brazing Pastes: Brazebinder is mixed with silver brazing
powder and flux, and a paste is prepared. The paste is applied and then
torch brazed. It is very useful in joining complex assemblies where use
of rods or performs are difficult.
- Dispensable Fluxes: Brazebinder is mixed with our specially
formulated powder flux to make a paste. This paste is used in automatic
brazing machines.
