MG Chemicals 8331S Silver Epoxy Adhesive - High Conductivity, 4 hr. Working time, 15 g, 2 Dispeners (8331S-15G)

Used it to repair torn foil connection on a back glass. Worked as described. Resistance added to connection was minimal.

Easy to work with. Made the electrical connection required. Sad I had to buy so much since I only used a drop of each; hope it stays fresh for the next repair '8^\

I really wanted this product to work, but it never cured at room temperature. I had it setting for a week and it is just a big mess of paste.....don't know if I am doing something wrong but I don't think so...

It works very well for cold solder.

Works good to attach two wires without soldering.

Good points: It’s almost as good as solder for electrical joints - certainly much better than carbon-based glue. So, it can be used for jobs that cannot be soldered, eg. aluminium. The electrodes of solar PV panels often consist of silicon layers on a glass base, whereby the electrical connections are fragile. They cannot be soldered, so this is an ideal application. Bad points: Although claimed to be ‘epoxy’, it’s nothing like as strong as (eg.) Araldite. Two-part epoxies will eventually cure - all chemical reactions (which effectively this is) are faster the hotter it is (a VERY rough rule of thumb is they'll take about half the time for every 10degC hotter). This product claims it will cure in 10 minutes at 65degC - way hotter than some jobs can stand. It also requires a ‘Glass Transaction Temperature’ of 35degC - which I take it means no useful curing below that. So, expect full curing to take ages! Fortunately, I needed to fix the solar connections during hot weather - it cured fine while I left it inside a very hot car during a long weekend, where it certainly got well above 40degC. The best electrical connection to the silicone electrode is a strip of copper - clean it all and use conventional solder to join the wiring to the copper strip. Then, use this product to join it to the silicon. Hold the joint while curing with (eg.) binding clips for paper, or G-clamps. But NB: I bought exactly the same product from Amazon in 2018 for a tad under 30 quid. Even accounting for inflation, over double now is way OTT. It claims a shelf life of 3 years. Given the converse during cold temperatures, this expensive glue should remain usable far longer when it's cold. Mine was perfectly fine after 8 years when kept in the fridge.

Good.product..

First lot was out of date so did not work properly. Second lot was fresh and was perfect.

Does not cure very well at all!
