G-855 poly addition cure rtv2 silicone rubber

1. Description

Guochuang G-855 is a two-component addition (platinum) cured silicone rubber which vulcanizes at room temperature. Because of its high hardness, strong strength, it is used for rapid prototyping, wax casting (foundries and candle makers), architectural restoration and for casting concrete. 

2. Features of G-855 platinum cure silicone

•High hardness

•High tear and tensile strength

•Very low shrinkage

•Fine detail reproduction

•Choice of catalyst and thixotroping agent 

3. Application of G-855 platinum cure silicone

•Moulding of masters

•Plaster moulding

•Moulding of large objects

•Rapid prototyping

•Cornice manufacture

•Tampo print pad manufacture

•Case making in the ceramics industry

•Moulding chocolate & icing sugar

5. Using instructions 

1.Place a plastic container on a small scale, making sure to zero out the weight on the scale. Note: use a container that, during rise under vacuum in Step 5, will allow for material to expand to 4-5 times its resting volume.

2. Pour catalyst into the plastic container, noting weight of material poured.

3. In the same container, pour an equal weight of base on top of the catalyst (e.g., 100 grams of catalyst and 100 grams base). Note: within a 5% weight variance, the end result is not altered.

4. With a clean, dry mixing spatula, mix energetically until the color of the product is homogeneous. Note: working time begins at this step. Mixing should take no longer than 1-2 minutes.

5. Place container under vacuum and vacuum until material bubbles and rises. Release vacuum and repeat until bubbles are removed. Vacuuming should take no longer than 3-4 minutes.

6. From a height of approximately 30 cm, pour the mixed silicone into the mold frame. Maintain the pouring stream in the same spot so as to minimize introduction of air bubbles into the mold.

7. Allow the mold to sit, undisturbed, for at least 4 hours to ensure the silicone is fully cured.

8. Remove the mold from the frame.

9. Cut around the pattern carefully to release it from the silicone rubber mold.
