User questions & answers

Question:	What is this. What does it do
Answer:	This is from Alka-Seltzer’s official website: Does Alka-Seltzer Plus® contain gluten? A: We don't add gluten to our products. However, we can't guarantee they are 100% gluten free since our products are produced in a facility that manufactures and packages items that may contain gluten.
Question:	do you have to clean it
Answer:	It works pretty well for me but it doesn’t last for a long period of time. I take it at bedtime so that I won’t be uncomfortable while I sleep—and it does the job. But I have noticed that sometimes in the morning, the gas comes back.
Question:	Is this specific Rosin Paste Flux #135 non-conductive
Answer:	It has corn syrup in it, doesn't say how many grams of sugar, that I see but it works great and I only take 1 when needed.
Question:	Will this work for soldering copper speaker wire together
Answer:	Thanks for your interest in Maty's! Our All Natural Acid Indigestion Relief can be used by anyone who can take a capsule (or the capsule can also be broken up). Hope that helps!

About

SRA #135 is a petrolatum-based soldering flux, containing Rosin and organic acid activator. Unlike many paste fluxes, it contains NO Zinc Chloride or Ammonium Chloride, making it ideal for electrical and electronic repairs. The Rosin also leaves a protective coating over the soldered area that can prevent corrosion.

Why Use Flux?

In order for solder to do its job, the layer of oxides on the metal surfaces you're soldering must be removed. A good flux, like #135, removes the oxides and sets the stage for soldering. The solder follows the flux, as if the flux were clearing a path for the solder and telling it where it to go. For many soldering applications, using only flux-core solder wire is sufficient. However, there are benefits of adding an externally applied flux such SRA #135, these benefits include:

Prep Surfaces

Prep the surfaces by removing any dirt, rust, grease, paint, and other contaminants with sandpaper, wire brush, steel wool, etc. For many applications, the residues can be removed with just a rag and some isopropyl alcohol. These impurities may prevent solder flow so it is important not to proceed until clean metal is visible.

Choose an Applicator

Various tools can be used as an applicator for the flux including toothpicks, acid brushes and spatulas. Wires and components can simply be dipped as well. One of the benefits of paste flux opposed to liquid is that it will stay put wherever you apply it.

Apply the Flux Paste

Using your applicator of choice, apply the flux to the target areas you are about to solder. The exact amount applied will depend on the job but in general use just enough to cover the area to be soldered in an even coating. Remember that the solder will flow to where the flux is so make sure to apply only where it is needed to prevent solder bridges and mess.

Apply Heat and Solder

Apply heat using a soldering iron or hot air gun to bring to melting temperature and solder. Remove heat and allow to cool. Remove residue with rag if wanted.

• Solder Wire: Included in the kit is a high quality 60-40 (Sn/Pb) Tin - Lead rosin core solder wire alloy with 0.6mm diameter and 1.6% flux content commonly used for wiring appliances, DIY projects, 3D printers and other electronic projects or electrical and electronics soldering and repairs
• Rosin Paste Flux: This high-quality 50g rosin flux soldering paste facilitates the flow of solder, thus increasing the efficiency of the soldering process and is just right for your small DIY soldering projects.

User questions & answers

Question:	Will this work on Aluminum
Answer:	I wouldn't use it for wiring as it is corrosive if left on the connection. Even with plumbing I wipe it off after it cools down enough to handle. Wiring uses a flux core solder.
Question:	is it liquid or paste
Answer:	I have never used it on silver but La-Co does make a flux for silver brazing. It must be some chemical in the flux.
Question:	can it be used on sterling for jewelry
Answer:	I have used it with 63/37 and 60/40 tin lead solder. A small amount of the paste works well and my overall results have been excellent. Just remember to wash part in water after soldering and part is cooled.
Question:	Can this be used on gold fill and solid gold
Answer:	Hi, no I wouldn't use it for electronics, PCB's etc,I have seen it does corrode over time,there's better flux available for that application, this stuff is really good on general wiring and the like where it's enclosed with heat shrink, trailer wiring, car repairs and the like, hope that helps

Why use solder flux paste?

The solder flux paste leaves a protective coating in the welding area to prevent corrosion. Improve efficiency and speed up the welding process, with less time to let the solder flow to where you need to provide more controllable and accurate welding.

Our rosin soldering flux paste

1.Anti-oxidation and non-corrosive.

2.The boiling point is slightly higher than the melting point of the solder. As the solder melts, the solder begins to boil and absorb heat, thus keeping the temperature of the electronic components and PCB at this temperature.

3.Applicable to the mobile phone, PC board and other precision electronic chip level welding.

Specifications:

Dimensions:

Diameter : 6.3cm/2.5inches

High: 3cm/1.1inches

User questions & answers

Question:	Why are people using this for electrical wiring if it says for plumbing
Answer:	This is made of professional grade rosin and petrolatum (vaseline). The paste consistency is very close to that of vaseline.
Question:	The la-co flux is not supposed to be used to solder silver. why would this be
Answer:	This is flux paste, It is for soldering wires together most rosin flux core solder already has it inside the solder But it some cases you will need to apply a little to wires that does not contain rosin flux Hope this helps....
Question:	Can this be used with lead solder
Answer:	This isn't a product that you have to clean.
Question:	Since this is water soluble, can it be used on pcb's and electronics? will it corrode over time? it's non-acid
Answer:	I don't think there are any components in flux that conduct electricity. You can wash it off after soldering with the proper solvents, which is probably the best policy.

Answer:	Yes. It easily melts through the plastic casing and allows for quick and easy tunneling of holders for human souls
Question:	Would this work for well pump wiring 200’ plus underwater? #12 wire and with a blowtorch
Answer:	It gets hot enough to melt plastic. so when you say "welding" you mean melting two plastics together, I believe it's feasable is small applications. The heat generated by a soldering gun is directed at the top and in small precise applications.
Question:	Will this adhere with silver plated terminal connectors
Answer:	5 mm is too big you will have to file it down a little, but then it will go in. The tip is secured by a phillips head screw. it works good.
Question:	is flux required
Answer:	Yes, can works.

We can provide manufacture date and lot number. However- for most purposes, even though this has an expiration date of 2 years, it will work just fine for a long, long time.
Question:	it shows electronics being soldered, does this come with the correct solder for use on electrincal boared or will that need to be purchased seperatly
Answer:	I to have been using rosin core solder for 65 years. Today's slim solder does not have enough rosin. This flux works great and the tip lets you use only a small drop. Phonodoc
Question:	Is the solder acid free
Answer:	Thanks for buying this product! We actually have not heard of any problems with this. However, this flux is really sticky stuff due to the rosin content. Isopropyl (rubbing) alcohol is a great solvent and clean up tool for this flux, and it's the major component in this flux. It's worth buying a bottle. Buy 90 percent alcohol if you can find it, but 70 percent works fine too. We can actually buy either one at our corner Dollar Gen store for about 2 dollars here in Kentucky. Soak the tip in it and you will be good to go!
Question:	What is size of storage box
Answer:	The cap is for storage (this one comes attached to the bottle when it arrives). The second tip is for dispensing purposes and should be cleaned with rubbing alcohol after each use, this will keep the tip clean and free from any residue that may stay in it after use.
