This EPOXY THICKENING additive makes epoxy more strong when it is used to bond hardware or when there are going to be a lot of cycles. For filling gaps, making structural fillets, or where you need a very strong bond, you can mix epoxy with water. Then mix it with any combination of WEST SYSTEM 105 Resin and 20X Hardener, G/flex Epoxy 650, or G/5 Five-Minute Adhesive to make it stronger. When epoxy is mixed with it, it will turn off-white.
A lot of people use this filler to make HARDWARE or STUD BONDS. Even a small amount of this 404-High Density added to a mix of epoxy resin and hardener will help the epoxy not move when it’s cured. This filler should be mixed with liquid epoxy to make a slurry. It should be thick enough to stay in a horizontal hole, but not so thick that it doesn’t move. (Putting too much filler into epoxy can make it hard to get air out..
Add this high-density filler to thick epoxy to make a non-slip adhesive that can fill in big gaps. It will make wood joints very strong, which will save you the time and effort it takes to make tight joinery.
FOR THE MOST STRENGT. In this case, you should add just enough to fill in all of the gaps between surfaces without sagging or running out of any of the places where you are filling. Some should come out when the joints are clamped or hardware is put in. The mixing cup shouldn’t be more than 1/3 full of epoxy before adding the filler.
The amount of filler you add to epoxy affects how thick it is. For hardware bonding, mix 404 High-Density filler into epoxy to make a slurry that isn’t too thick. It should be thick enough to stay in a horizontal hole, but not so thick that it doesn’t move. The chart below shows the differences between epoxy that hasn’t been thickened and three popular types of thickened epoxy: “catsup,” “mayonnaise,” and “peanut butter..
Great: This is an easy way to thicken your resin. When mixed with epoxy resin, this glue is very strong.
