Is this a good thickener for use with alumilite quick set rtv silicone?

The Thi-Vex is normally used to thicken brush-ons like the rebound 25 silicone which checks its tendency to flow especially when the object being molded is in the vertical. The alumilite quickset silicone is not a brush on silicone. It is meant for pouring and therefore does not need the thi-vex thickener. If you make it thicker, it will be difficult for it to copy very intricate features.I hope this helps.

Will this work with Mold Maker by Alumilite?

We don't test Thi-Vex with non-Smooth-On silicones.

Can I use this with OoMoo30?

It will work for OoMoo30, but I had much better results using rebound 25 with the thivex

Very disappointed.

WARNING: DOES NOT THICKEN Polycraft GP-3481F RTV Silicone. I added lots of drops to no avail. So I ended up having to do loads of silicone layers to compensate. I know it works with ither silicones, smooth-on silicones for example, because I've watched countless videos of it working (my reason for using it). Very disappointed, but now I know. Thought I might need a pipette, but product has handy dropper already. Easy to control quantity dripped with care. Easy to remove lid.
