    Default How to thicken epoxy

    Thicken as in turn it into a really thick paste - so it can be applied with a spatula

    I bought some 'aerosil' which can thicken it but its very difficult to mix in theres always clumps. Any other options?

    Anyone tried using timbermate wood filler to thicken it? Doesnt need to be structural just want to fill some checks/gum veins

    Keep mixing the aerosil, all of a sudden it will merge with the resin, and then you can add more if desired. Just use a flat stick, an offcut of 3 mm ply is what we use, but it does take time, longer than you expect.

    I wouldn’t use Timbermate it’s a water based filler. Maybe try feeding in your filler more gradually rather than all at once. It’s one of the tedious things about epoxy , mixing in the fillers unfortunately. Sometimes while mixing if I think I’ve added to much I’ll blow off the excess before it becomes too stiff. Dont tell te OHAS rep I said that!

    I understand that adding talc to epoxy will achieve what you are looking for. (preferably non scented talc). Mix to a paste.

    Epoxy is thickened with micro balloons. You can purchase it at Bunnings. An alternative is bicarb (but this makes for a heavy solution). Flour is another alternative.

    I read talc does it - Im a bit worried about baby powder as it has other stuff in it not sure if it will be bad for the epoxy?

    Is there another name for micro balloons? I searched bunnings and nothing came up

    Don’t use anything but the correct micro hemispheres, they cost very little and are engineered to blend with the epoxy resin correctly.

    just keep mixing it, all of a sudden, it will just blend and merge and you’re away.

    I cannot find the link to Bunnings. Probably old now. You can order these on line: SIG Micro-Balloons - Filler Material - HTA

    I used micro balloons thickening epoxy when repairing surfboards and windsurfers.

    West System needs fillers to thicken it up, but Techniglue is a lot more "gluggy"* in standard form.

    Techniglue already has fume silica thickening hemispheres in it, same as araldite and other epoxy glues.
