Product Description

This MG Chemicals 421 Liquid Tin is a clear immersion tin for coating a copper substrate or solder deposit with a dense tin coating. It tinplates copper circuits on PC boards in 5 minutes or less at room temperature for immediate soldering capability. It leaves a dense coating, and it contains no co-deposited organics for strong resistance to oxidation. Liquid Tim can be readily soldered, has a long shelf life, and does not require mixing or diluting. Residues can be rinsed away with warm water for easy cleanup. Liquid Tin will cover 3600 square inches of board per half liter of solution, and it is Restriction of Hazardous Substances (RoHS) compliant. This solution is strongly acidic; protective gloves, clothing, and eye protection must be worn.

This product arrived on time and as advertised. I create custom PCBs for my electronic projects and this product is totally amazing. After etching the copper boards a quick dip in this liquid applies a tin coating that makes soldering components very easy as well as protecting the copper traces from oxidation. i recommend this product and vendor.

It is good stuff. It will instantly change copper to tin traces on a printed circuit board. Dip it in solution and its good to go.

Get a small plastic funnel, some shallow tupperware, and follow the directions.
This works quickly and doesn't produce tons of fumes. Outside use is recommended though. You won't be out there long.

Enjoy!

SRA contacted me to say the product was backordered, but despite splitting the shipment everything arrived before the expected date. Not my first purchase from SRA - and will definitely not be my last.

Easily the best liquid tin solution I've used (25+ years). Kinda stinks tho, so make sure you have good ventilation.

Fast working, and works at room temperature in just a couple minutes. For best results, go over your board with some scotchbrite or sandpaper. Once you rinse off the board the end result is an even dull tin finish. You won't be able to scratch it with a fingernail, but a sharp object with light pressure can scratch it. I bought it to dip my Radio Shack brand prototype boards since I have enough to last a few years now. :)

First time I have used this product for plating printed circuit boards but will use nothing else in the future. Unlike the other granular product that is typically used, this requires no mixing or heating to tin plate a PCB. Liquid Tin beautifully plated a board in 3 minutes at room temperature. The plating solders easier at lower iron temperatures.

Great product!
