Liquid silicone rubber for gypsum casting specifications:

Brushable/Pourable

45 Minute to 1 hour working time, 24 hour cure; Cure rate can be adjusted by applying heat

Produces extremely fine detail from original

Self releasing, no mold release agent required for most applications

High heat range, up to 400-Degree F

easy to use, odor free, non-toxic, two component silicone rubber.

1. 1.       get necessary tools prepared, clean the original model thoroughly and fix it on the wooden board.
2. 2.       Brush a layer of mold releasing agent ( Vaseline) on the surface of the original product, cut proper size of hard paper board according to the height of model, enclose it.
3. 3.       Choose the right type/model of silicone based on size, structure, pattern and application of the product. Here we use silicone J-1225 (or J-1220) of Jenova Brand, add 2%-5% catalyst into the silicone, blend it evenly and then put it into vacuum pumping machine to deair.
4. 4.       Pour the vacuumized silicone onto the products, get products fully and evenly flooded.
5. 5.       after the silicone cured completely, pull down the paper boards, you can take out your products, then a mold is formed.
6. 6.       note: Generally, in this pouring way, you should use low-hardness silicone rubber to make molds, so it will be easier to demould and will not destroy the products.

How to avoid air bubbles in silicone molds and models?

1)apply a thin layer of silicone to the frame and the model before pouring the full amount;

2)raise the silicone about a foot in the air and pour it slowly;

3)remove air or deair the silicone rubber with a vacuum pump within 10 minutes.

4)hold the box at an angle and pour the silicone in on the raised end.
