Blockade: Faster than Soldering
A Novel Silicon Brazing Discovery…
Brazing alloy paste for copper and brass
Nothing blocks like Blockade. Today’s lead-free
solders, including the BRIDGIT-require considerable
skill to make a good cap. It requires a good deal of
time for the plumber to locate his cleaning tools -
fluxes (the right flux: non-acid, water-soluble, etc.) -
and to be sure that the person doing the soldering
knows how to cap. Clean-up is also advisable.
It is very difficult to make a braze with
Blockade without making a cap. Just try it!
Blockade Melts Like Ice Cream on a Cone
Parts of Blockade turn liquid faster than other
parts. The more liquid portion fills the capillary right
away while the “cap” remains in place, like an ice
cream cone when the melted part runs down the
cone, yet the ice cream remains thick on top. Once
the cap forms around the top of the connection, the
braze is complete. The strong smooth cap is a gastight,
liquid-tight, permanent seal.
Bloackade performs two brazing fuctions
simultaneously. Blockade quickly builds and holds a
large cap while it fills the capillary at the same time.
The capillary space is very small and requires a
very minimal quantity of brazing alloy to become
totally full. Only about 10% of the cap is utilized to
fill the capillary, and the capillary is filled during the
time the cap is made. Regular phos-copper alloys
without silver are very fluid and will not only
penetrate into the capillary but will continue to
“penetrate,” flowing brazing alloy through the
capillary into the interior of the tubing. This extra
fluidity makes capping very difficult.
Flux-coated BLOCKADE brazes copper to brass
and brass to brass. Brazes are very strong and
Blockade is the brazer’s best answer to quality,
because it is faster than soldering, and even the
novice can easily make a very good cap.
