This is perfect for thickening up epoxy for dioramas and resin art. Just add slowly and mix thoroughly.

A good thickening agent for epoxy.

I needed something to thicken some silicone fluid and this stuff did the trick.

Thickened up my resin for mold making. But not a lot of value per ounce. Seems a little pricey for the small amount you’re getting.

Hard as a rock

Definitely good product
