KEY-209 Halogen-Free, No-Clean, Lead-Free Flux
Product Highlights
| Lead-free and environmentally friendly formula | Halogen-free ingredients | No cleaning |
| Good wettability | Wide applicability | Low smoke, no irritation |
KEY-209 soldering flux; composed of high-quality modified rosin resin, organic active agent, various additives and solvents.
This soldering flux has excellent solderability, full and bright solder joints, good tin penetration, and uniform tinning; it can meet the welding needs of various lead-free solders and is an ideal no-clean soldering flux for lead-free solder welding.
Product Features
Effectively reduce the surface tension of lead-free solder, improve the fluidity and solderability of solder.
Strong wetting ability, good through-hole tin penetration, can effectively make up for the shortcomings of poor tin penetration of lead-free solder.
The post-soldering residue is spread evenly, with good finish and superior electrical reliability.
It does not contain environmentally prohibited substances such as RoHS and is an environmentally friendly flux.
Scope of Application
This product can be used with various lead-free solders and is widely used in power products, computer motherboards, graphics cards, communication equipment, audio and video equipment, refrigeration equipment, medical equipment and other electronic industries. It can be used by spraying, dipping and foaming processes.

Please Note
After opening this product and taking out the used part, the lid must be closed tightly to prevent the solvent from volatilizing and causing a change in specific gravity.
Used flux and unused flux cannot be placed in the same packaging barrel. After the flux is opened, if there is residual flux in the barrel, it cannot be left open to the air, and the lid should be tightened as soon as possible.
The container containing the flux should be kept clean to prevent dirt and other substances from mixing into the flux and affecting the quality of the flux.
If there are special requirements for electronic products, it is recommended to do relevant compatibility tests.
For safety protection and other precautions, please refer to the MSDS of this product.
