## Questions & Answers

**Q: Why is this one white compared to other ones that look tan or brownish?**
A: This is a ‘No Clean’ non acid flux  I use it for electronics when I don’t want the acid and heavy residue left by the ones that are darker

**Q: is it lead free?**
A: The maker's description posted right on the Amazon ad says the product is lead free.

**Q: Where is the specific temperature information?**
A: You have to do your own research on this.  This product's melting temp as right around 350 degrees F.

**Q: Is this like a solid wax or a soft paste that can be applied on the PCB? some are labeled as paste but they’re like solid.**
A: This is made of professional grade rosin and petrolatum (vaseline). The paste consistency is very close to that of vaseline.

The Thermaltronics TMT-FP-1 Rosin Flux Paste is a dependable, high-quality flux designed to improve solder flow, enhance wetting, and reduce common soldering issues like cold joints or bridging. Compact, easy to apply, and formulated for electronics work, this rosin paste is a reliable choice for hobbyists and professionals alike. 🔥 Flux Performance & Chemistry Rosin flux plays a critical role in soldering by cleaning metal surfaces and promoting better solder adhesion. The TMT-FP-1 excels in this core function: Improves wetting: Encourages solder to flow smoothly into joints Cleans oxide layers: Helps remove stubborn oxidation on pads and leads Reduces defects: Minimizes cold joints, incomplete flows, and bridging when used properly 📌 Verdict: A solid rosin paste that noticeably enhances solder performance compared to “no flux” or generic alternatives. 🧴 Ease of Application One of the strengths of this product is its user-friendly paste form. The consistency makes it easy to place exactly where it’s needed — especially useful for fine-pitch work or dense boards. Paste format: More controllable than liquid flux Application tool: Often used with a small brush, toothpick, or applicator Non-messy: Clean paste that doesn’t run or drip excessively 📌 Verdict: Very approachable for beginners and convenient for seasoned technicians. 🛠️ Use Cases & Compatibility The TMT-FP-1 Rosin Flux Paste works well in a variety of soldering scenarios: ✔ Through-hole and surface-mount components ✔ Repair and rework projects ✔ Leaded and lead-free soldering (with appropriate temperature adjustments) ✔ Circuit boards with minor oxidation 📌 Verdict: Versatile enough for most hobby, repair, and light professional soldering tasks. 💡 Thermal & Residue Behavior Rosin flux tends to leave behind slight residues — but this formulation maintains a low-residue profile that is less likely to cause issues in finished assemblies (though cleaning might be recommended for sensitive electronics or optical circuits). Residue: Light and non-corrosive Temperature range: Performs well within typical soldering ranges 📌 Verdict: Good balance of activity and cleanliness. 📦 Packaging & Size The paste comes in a small, sturdy tube or jar that’s easy to store on a workbench. The size is convenient for occasional use, but frequent solderers may find themselves returning for refills sooner than with larger bottles. Package: Compact and bench-friendly Storage: No leakage; resealable 📌 Verdict: Practical packaging, though larger size options would be nice for heavy users. 🔎 Pros Encourages improved solder flow and wetting Easy to control thanks to paste form Works well for both leaded and lead-free solder Low-residue rosin formula Great for detailed PCB work and component reflow ⚠️ Cons Smaller quantity — may require frequent replenishment for heavy users Rosin flux residue still exists — cleaning recommended for certain sensitive applications Not as active as some high-activity no-clean flux pastes (but remains safer for general use) ⭐ Final Verdict The Thermaltronics TMT-FP-1 Rosin Flux Paste is a solid, reliable flux that enhances soldering performance by improving wetting, cleaning oxidation, and reducing common joint problems. Its paste format makes it easy to use precisely where needed, and the low-residue rosin formulation is appropriate for a wide variety of boards, components, and skill levels. Whether you’re a hobbyist stepping up to more complex projects or a technician focused on cleaner joints and better consistency, this flux paste is a practical bench companion that delivers noticeable results.
