G-805 soft platinum catalyst liquid silicone rubber

1. Description

Platinum cure silicon also called Poly-addition silicones, are ideal silicone casting rubbers. They are excellent for moulding with a fully enclosed mould, as they cure at room temperature conditions. Platinum silicones are very stable. They have very low, or no shrinkage, we supply them in a wide range of hardnesses (Shore A) and they have very high tear strength, excellent mould and library life.GuoChuang G-805 is soft platinum cure silicone, with 5 Shore A hardness, which is widely used for cast film special effects, silicone mask, Orthotics & Prosthetics, silicone insoles and so on, moulding of master, moulding of chocolate and ice sugar.

4. 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. 

4.Appearance
