.like: generous quantity at a very competitive price..

Yes this worked perfectly for the project I needed it for. It is a Glue. I tested it before applying it for my project. The issue I came across, was in just one day, even with the cap tightened down, there was a hardened crust that I had to break through to use the glue. I am wondering if the whole tube will be hardened the next time I go to use it.

I used this to glue some large heat sinks to an LED array's aluminum panel and it worked great. I have no way to test the thermal conductivity but the light runs much cooler now and the heat sinks get hot so it must be transferring the heat. Better than thermal grease if you want your heat sink to stay in place permanently.

Used for gluing powerful LED driver to the heatsink. No problems found.

works great!
