What Is Our Silver Bearing Solder Paste?

Our Iso-Tip silver solder paste is made out of ultra-fine premium refined powder metals. With a 98% tin and 2% silver mixture combined with the flux you need to prevent rust. The silver bearing solder paste has a free flow melting point of just 400°F. Meaning you can melt our solder paste with just one match! Because it uses the ultra-find powder, the silver solder paste has a strong bond – 10x strong than typical 60/40 solder. With the microscopic size of the metal particles, it creates an extremely low melting point.

Iso-Tip Solder Paste vs. Wire Rod

One of the benefits of solder paste over soldering wire is its ability to act as a helping hand. When you use our solder paste, the viscosity of the paste allows it to hold lightly hold small objects. This frees up your hands to create a proper joint. Yet another amazing property of this special blend of silver solder paste is to solder both ferrous and non-ferrous metals. Even better, the flux is mixed right into it. This means you don’t have to swap out your solder mid-way through a job just because the machine you’re working on has two different boards.

The Versatility of Solder Paste

There is no solder job that is too tough for silver solder paste. There are the normal applications like soldering pipes and building boards. We have also heard from customers who have used our products for some pretty odd jobs. Including: people using it to fix their guitars or to plug a hole in their coffee tumbler. We have even heard of customer who made a 25-foot cord for the cell phone charger. There are many things you can do with our solder paste. If you think you’ve done something that would stand out. Or maybe something we may not have thought of let us know. We always like to hear from the people who buy our products. Drop us a comment below!

How To Use Silver Solder Paste

Thoroughly clean joint area to be soldered. Remove cap from syringe and push plunger to apply the silver solder paste along joint area. Pull back slightly on plunger to stop flow of solder paste. Using a torch (recommended for most applications), place tip of flame 1/2″ from solder paste and evenly heat metal from one end of joint to the other, back and forth until paste breaks down and flows out (this will occur when metal temperature reaches 430°F). Soldering operation should be rapid to prevent burning of flux. If flux burns because heating was not rapid, residue will turn black or brown.

For certain electrical work such as battery terminals or circuit board work, a soldering iron is recommended. A small dab of silver solder paste should be spotted to the work piece and a hot soldering iron should be applied to the area to be soldered. Allow to cool and wash off flux residue using warm water and a stiff brush. You will have a superior silver finish solder joint or connection that will not blacken or tarnish.

Storing Solder Paste

Silver Solder Paste needs to be stored at room temperature (78°F to 60°F). If stored in heat, material will thin and the flux and binder will tend to separate and a clear fluid will flow from the nozzle. If this occurs, cool the material to room temperature then stand the syringe upright with the plunger down and the nozzle upright. Take a thin wire and insert it into the nozzle and push down to penetrate the paste material to absorb the fluid by the paste. Leave the syringe upright for approximately 10 minutes. The solder paste should then be ready to use. If the paste is cold or frozen, bring the material to room temperature and use the same procedures as those used above.

Other Silver Solder Paste Details

• No mess, no waste syringe
• Ready to use – flux blended in – just add heat
• Low melting point – flow smoothly at 430°F, re-melts at 650°F
• Solders most metals
• Use with butane torch, soldering iron, propane, acetylene, or mapp gas torch.
• Finished joint is strong than base metal used – tensile strength up to 28,000 psi
• 5X stronger than conventional solders
• Extremely high electrical conductivity
• Stress and vibration resistant
• Provides strength without the distortion of high temperature brazing

How To Use Silver Solder Paste with the Butane Titan Torch and Solder

Have you ever needed to solder wires together, but not sure what to use? Here’s a photo of an infinite-color LED package that was soldered together.  One pair of wires used the ISO-TIP silver bearing paste the other used standard solder.  Both worked well but the solder was a little hard to hold on while holding the torch and the wires.  The flame singed the wires a little too but not bad.
