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
