Used for solder touch up, repair, or rework surface mount assemblies via brushing or dispensing. Review: Great flux - Great flux works perfect for fpv builds. Review: Perfect for desoldering - I love this stuff for desoldering through hole components. The synthetic and no clean fluxes on the market just aren’t penetrative enough when mixing unleaded with leaded for through hole desoldering work. This is the only stuff I trust that won’t have me overheating the PCB. Synthetic stuff is great for surface mount but you just can’t beat real Rosin flux for through hole! It does have the downside of having to clean it much more thoroughly but it’s worth it to not be battling different heat settings for different types of solder. ## Features - Excellent wettability - High tack force - Long tack time - Perfect flux for electronic repairs - Rohs compliant ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MS04SO4 | | Best Sellers Rank | #76,640 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #77 in Soldering Flux | | Brand | MG Chemicals | | Brand Name | MG Chemicals | | Color | Amber | | Container Type | Jar | | Customer Reviews | 4.6 out of 5 stars 2,231 Reviews | | Full Cure Time | 1 seconds | | Global Trade Identification Number | 00779008834206 | | Item Form | Paste | | Item Package Quantity | 1 | | Item Type Name | Flux | | Item Weight | 0.1 kg | | Manufacturer | MG Chemicals | | Material | Rosin | | Material Type | Rosin | | Model | 8342-50G | | Number of Pieces | 1 | | Part Number | 8342-50G | | Specific Uses For Product | Soldering | | UPC | 779008834206 | | Unit Count | 1.76 Ounce | | Volume | 1.25 fluid ounces | | Warranty Description | warranty@mgchemicals.com | ## Product Details - **Brand:** MG Chemicals - **Color:** Amber - **Item Form:** Paste - **Material:** Rosin - **Specific Uses For Product:** Soldering ## Images ![8342 RA Rosin Flux Paste - Image 1](https://m.media-amazon.com/images/I/41JkZ1-E-EL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great flux *by R***K on February 6, 2026* Great flux works perfect for fpv builds. ### ⭐⭐⭐⭐⭐ Perfect for desoldering *by V***R on July 25, 2024* I love this stuff for desoldering through hole components.
