Mold Making Minute: Mold Star 15

Use hot glue to secure the model. Glue the mold box to the base. Dispense equal amounts 1A:1B by volume. Dispense Parts A & B into mixing container. Mix Parts A & B as directed. Slowly pour into one corner of the mold box. Pour 1/2 inch (1.25cm) over model's high point. Allow Mold Star 15 to cure. Carefully remove the mold box. Slowly peel back the cured rubber. Mold Star 15 reflects perfect detail.

Mold Star® 15 is an easy to use Shore 15A platinum silicone that is mixed 1A:1B by volume (no weighing scale necessary). It features a relatively low viscosity and vacuum degassing is not required for most applications. Pot life is an extra-long 65 minutes.

Mold Star® 15 cures overnight to a soft, strong rubber that is tear resistant and exhibits very low long term shrinkage. Molds made with Mold Star® will last a long time in your mold library and are good for casting wax, gypsum, resins, concrete and other materials. Mold Star® 15 is heat resistant up to 450°F (232°C) and is suitable for casting low-temperature melt metal alloys.

Note: This product will not work with modeling clay containing sulfur under any circumstances.

Where can I get this from

[SmoothOnInc]

A list of our US and International distributors is available on our website (link in the description). We also sell trial and gallon-size units on our website for orders within the US.

Once you create the mold, is it safe for making chocolate in it?

[SmoothOnInc]

We do have silicone rubbers with food ratings but Mold Star 15 is not one of them. You might want to look into our Smooth-Sil 940 or our SORTA-Clear series.

If I have some of Part A and Part B Mold Star 15, which is unmixed, can I store it and use it at a later time, or do I have to use ALL of it as soon as I open the bottle?

[SmoothOnInc]

It does not all have to be used in one shot. That said, we do recommend using it as soon as possible. You can find more information about shelf life on our website.

Yes, Smooth-Cast 320 can be used in a Mold Star 15 mold.

Could I use smooth cast 320 to pour into a mold out of this material?

[mpxz999]

My object was made out of dried paper clay.

I hot-glued a plastic milk cap to the bottom of this shape.

I hot-glued the top of the cap to the BOTTOM of the mixing cup.

This made it so my pear shape was held up in the middle of the cup by this cap at the bottom (that would later be a fill port).

The hot-glue between the plastic cap and the bottom of the cup just gave way as my containment was nearly full... I could not find a way to reattach the two before the silicone cured... Waste.

[SmoothOnInc]

Can you explain a bit further? What were you bonding the mixing cup to using the hot glue?
