Description
Making your own flexible and sustainable molds is easier and faster than ever with Craftiviti’s Mold Maker RTV Silicone Rubber! RTV stands for Room Temperature Vulcanising which means the silicone will cure at room temperature so our Mold Maker RTV Silicone Rubber doesn’t require any additional heat to cure.
The silicone rubber will cure and become a strong and flexible rubber that is tear-resistant and good for multiple uses. Molds made with our Mold Maker RTV Silicone Rubber are suitable for casting using liquid plastic, epoxy resin, concrete, soaps, candles and others.
Each Mold Maker RTV Silicone Rubber comes with a 50ml Hardener (Catalyst)

Instructions:
- Stir Mold Maker RTV Silicone Rubber. Pour desired amount into a mixing cup.
- Shake the Hardener bottle. Drip 3% of Hardener to the total weight of RTV Silicone. Stir mixture.
- Pour mixture slowly over master object to avoid bubbles.
- Depending on size, the silicone will set within 2 to 8 hours.
(Always spray master object with Silicone Mold Release agent)
*Please note that the stirring and measurements of this silicone rubber must be precise. Read product warranty below*
NOTE:
- 3% of hardener provides a more fluid mix with a longer work time.
- 4% hardens faster with a shorter work time.
- When using any clay or release agents, please ensure the items contain NO SULFUR as sulfur will inhibit the curing the silicone rubber.
For 2 part silicone-to-silicone molds, you will need to apply a generous layer of mold release agent, otherwise the mold will not separate.
Cured Silicone Rubber can withstand casting heat up to 100 °C.
***
There is no warranty for this product and it is up to the end user to determine the suitability and the end result. Please read the instructions above clearly before starting. When making a 2-part mold always use a generous amount of non-sulphur mold release agent as silicone will fuse to silicone. Always conduct a small scale test before attempting on a larger scale.

Easy to use. Thanks Craftiviti.

Welcome Hanif! Have a great day! And Happy Crafting!

Not so newbie friendly because hardener does not have colour, quite difficult to see whether it is properly mix or not. Overall im quite satisfied with the product.
Craftiviti (store manager) –
Hi Jason, we too wish the hardener has some pigment to indicate the mixing completion. However the pigment kept caking up. Thank you for your feedback and we are happy the RTV works for you. Happy Crafting!

Question:
1)What is the amount should I use to mold a bottle sized around a normal ‘beer’ bottle? 1kg sufficient?
2) To mold a glass bottle, do i need a release agent? Does the silicone will stick to the bottle like a normal caulk gun silicone did?
Craftiviti (store manager) –
Hi Azrul, thanks for writing.
1) 1kg should be sufficient for a standard beer bottle however, do take into account wastage using the mixing process. Keep your mold cavity small to save on more RTV usage.
2) Best to use with a mold release agent. Makes removal a lot easier.
Hope this helps.

Faizal Azmi –
Hello.
What is the shore hardness scale, pot life, cure time?
What color is this silicone after cured, and do you have additional color pigment for this product?
If using it without agent release, will it bond to the subject? Because that’s what I’ looking for.
Thank you

Hi, it say 3-4% hardener, can you give me the formula to calculate. My math is bad
Simon Foo (store manager) –
Hi there, the 3% – 4% is depending on the total Mold Maker Silicone Rubber used. For example, if you are using 1kg(1000g) and 3%, the calculation would be 1000(g) x 3% = 30ml.
