Its fast wetting, non-corrosive, and RoHS-compliant formula ensures clean, efficient soldering ideal for PCB prototyping and repair, minimizing residue and mess. ## 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: Was able to use on my last soldering project and it was awesome - This was one of my best experiences using flux at home. My other syringe of MG Chemicals flux worked well with soldering but was a slow messy process to get out of the syringe. With these pens it is SOO much easier. These are no clean but it still leaves a flux trace after soldering. This residue does dry firm so it is not a goopy mess like previous fluxes which is also a huge plus. Review: Great flux pens. Get worse as they get older, but cheap enough to purchase twice a year or so. - Like most MG chemicals stuff I've tried, these work great. Potent, little residue, and great flux consistency. In a pen like this, especially when working on SMD boards, the viscosity of the flux liquid is important. If it's too thin, when you heat up the device you're soldering, the flux will run everywhere. This product has consistently made SMD soldering a breeze. Sticky. ## Features - For leaded and lead-free solder - Fast wetting - Non-corrosive - Non-hygroscopic - RoHS compliant ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 789 Reviews | ## Images ![835-P Rosin Flux Pens (2 pack) - Image 1](https://m.media-amazon.com/images/I/61Lzg-1HpuL.jpg) ![835-P Rosin Flux Pens (2 pack) - Image 2](https://m.media-amazon.com/images/I/81BpdhEX9PL.jpg) ![835-P Rosin Flux Pens (2 pack) - Image 3](https://m.media-amazon.com/images/I/71-cIhCD9FL.jpg) ![835-P Rosin Flux Pens (2 pack) - Image 4](https://m.media-amazon.com/images/I/81DR+rmBQ3L.jpg) ![835-P Rosin Flux Pens (2 pack) - Image 5](https://m.media-amazon.com/images/I/81Yi8n+SOrL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Was able to use on my last soldering project and it was awesome *by D***. on February 22, 2021* This was one of my best experiences using flux at home.

Sticky. ### ⭐⭐⭐⭐⭐ Effective and convenient *by N***S on January 19, 2019* I bought the 2x pack of flux pens. The first one was extremely difficult to press down and ended up breaking and just leaking flux everywhere. BUT amazon refunded me half of this order. The second pen was very easy to press down and saturate the tip. Probably just a fluke on the first one. If that happens to you, maybe saturate the wick in ethanol or IPA and then press down again, don't force too hard. --- ## 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/74823097-835-p-rosin-flux-pens-2-pack](https://www.desertcart.tn/products/74823097-835-p-rosin-flux-pens-2-pack) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-01*
