Its non-corrosive, RoHS-compliant formula ensures clean, reliable solder joints ideal for prototyping, rework, and repair on PCBs and surface-mounted devices. Compact and long-lasting, it’s engineered for professionals who demand efficiency and quality in every stroke. ## Description DESCRIPTION: the 835-p rosin flux pen contains a Type RA rosin-activated flux composed of Pure water white (WW) grade gum rosin. It is a unique solvent system that contains very effective activators. The superior fluxing remains consistent throughout the entire aeration process. The 835 provides fast wetting action and complies with all requirements for Type Rom1 flux per j-std-004. Application: the 835-p pen is designed to dispense flux in a precise application and used for leaded and lead-free chemistries. Excellent for prototyping and rework/repair on printed circuit boards. Works well on chip carriers, heat sinks, surface mounted device pads, switches, and sockets. Application instructions: the flux pen controls the flow via a spring-loaded felt tip. This helps keep evaporation to a minimum between use. 1. Depress the tip against a hard surface until the felt tip gets wet, but not flooding. 2. Gently brush the wet tip onto the soldering area to apply. To keep the felt saturated and the flow controlled, only press in the tip as needed. Attention! do not continuously keep the tip Depressed or do not press too hard. This can jam the Valve open and cause flooding. Note that a fresh felt tip will take a several seconds to fully saturate, so expect a delay before the flux starts to flow on first use. Moving the tip in circular motion can help loosen the felt fibers and speed up the saturation process. Review: I wish I had tried this sooner!!! - I was surprised at the quality of this flux pen! A quick brush of the wire/base to be soldered, and boom - easy joint! No mess/spilling/waste/brush of a liquid dispenser, no goop of a paste. I solder infrequently (this one pen will probably last me a year), but this will be the only way I get my flux in the future. It is slightly more expensive to use the pen applicator, but it is my opinion that the ease of use and the results more than justify the extra expense. If you solder a lot, you may wish to go another route...but I would recommend giving the pen a try. I love it and won't be going back!!! Note: When first starting, you have to push in the tip a little bit to get the flux to flow...after that, you are in business and it is smooth sailing! Review: Best Solder Flux Pen for the money - I used this on a recent project and was surprised that it didn't come rushing out and run all over the place. A small dab is all it took for most of parts I was assembling. It becomes tacky quickly, so it helps hold the piece in place while you set the height of the component for through hole, for surface mounts it worked equally as well, tackiness was achieved in only a few minutes. You can always tell a good soldering job when you see it wicked through the lead onto the other side, which was the case every time when I used this flux. This pen should last a person a very reasonable amount of time. Clean up was a breeze, some rubbing alcohol an cotton swab was all I needed. If your on the fence about buying this, don't be, its money well spent. ## Features - For leaded and lead-free solder - Fast wetting - Non-corrosive - Non-hygroscopic - RoHS compliant ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0080X79HG | | Best Sellers Rank | #80,793 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #75 in Soldering Flux | | Brand | MG Chemicals | | Brand Name | MG Chemicals | | Customer Reviews | 4.3 out of 5 stars 309 Reviews | | Global Trade Identification Number | 00779008835661 | | Included Components | Satisfaction | | Item Form | Pen | | Item Nype Name | Flux Pen | | Item Volume | 0.34 Fluid Ounces | | Item Weight | 0.01 Kilograms | | Manufacturer | MG Chemicals | | Manufacturer Part Number | 835-P | | Model Number | 835-P | | Number of Items | 1 | | Primary Supplement Type | Lead free | | UPC | 779008835661 | | Unit Count | 1 Count | | Warranty Description | warranty@mgchemicals.com | ## Images ![835-P Rosin Flux Pen - Image 1](https://m.media-amazon.com/images/I/61Dc6CbggBL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I wish I had tried this sooner!!! *by A***N on January 27, 2017* I was surprised at the quality of this flux pen!

Helps with: * Stranded wire joints * Hand-soldering SMD pads (better solder wicking into joints; don't need to pre-tin pads) * Removing solder or re-soldering a joint Getting rosin to flow thru the fiber wick (too much, too little) can be tricky, so I'm docking a point for that. I usually keep a paper pad close by to start/verify flow. Also leaves more gooey residue which is only a problem in rare situations and can be easily cleaned off with isopropyl alcohol. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/10576073-835-p-rosin-flux-pen](https://www.desertcart.tn/products/10576073-835-p-rosin-flux-pen) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-16*
