Makes 2 part epoxy nice and stiff...
I used this to make 2 part 5min epoxy "stiffer" so it would not run downhill when used in small quantities.. this stuff is very, very light weight and quite fly-away and to use 5% by weight is actually quite a lot, I guess I use about half that amount and the epoxy goes about 80% of where I need it to be but just so much better than raw epoxy so its worth the fuss of mixing it... Really unique product, like it a lot!!

It requires Hardener, which is sold separately.
This is American marketed product. It requires the Hardener, which is sold separately. It was disappointing purchase, since it is not cheap in the first place. Realistically, you can go to Screwfix or Toolstation and buy ready to use off the shelf product. Not recommended, if you are thinking about quick use to fix some children toys holes or anything else. Simply buy Gorilla Epoxy Resin and it will work perfectly. Leo
