## Description

Why use solder flux paste?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 paste1.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:Size: Diameter: 6.3cm/2.5inchesHigh: 3cm/1.1inchesWeight: 1.2oz (35g)Package includes:2 x Rosin soldering flux pasteIngredients:Rosin: 40-50Synthetic resin: ＜10Solvent: ＜10Thixotropic agent: ＜5Active agent: ＜5Surface active agent: ＜3Additive: ＜5Physical properties:Physical State/Appearance: SolidVapor Pressure: Not ApplicableVapor Density: (Air=1): Not ApplicableBoiling Point: Not ApplicableSolubility: Insoluble in water, soluble in alcohol, ether, acetone, benzene, carbon disulfide, turpentine oil, oils and alkali solutions.Tip:1.Keeping out of reach of children.2.Harmful if swallowing; Irritating to eyes, skin and respiratory system.3.Scrub the surface of the object before welding, apply solder flux paste to weld copper, tin, iron and other metal, and then dissolve in the welding place with a soldering iron.

## Questions & Answers

**Q: Will it work to solder tin sheets, not wire?**
A: I am not sure, it is supposed to clean copper wire for easy adhesion of lead.

**Q: Where can i get the safety data sheet (msds)?**
A: The  company that makes it will have the SDS (Newspeak for MSDS) available for you.  UCalifornia generally has catalogued everything that has ever had a complaint or a suspicion of being not completely harmless

**Q: Does it work with lead solder?
Is it conductive?**
A: Yes it works with lead solder but this flux is meant for soldering electronics. If you are using 100% lead solder then you are likely using it for plumbing applications and therefore would want to use an acid paste flux.

**Q: is this flammable ?**
A: Not with normal use.
