addition cure liquid silicone rubber raw mate...

1.Description of addition cure liquid silicone rubber
G-830 silicone rubber platinum cure silicone rubber. The silicone rubber will be cured under room temperature and can be cured fastly by heating, It’s two-components liquid silicone rubber , the mixing ratio is 1:1 . It has an exceptional fluidity and good operability.Especially ,the platinum cure silicone rubber has a lower shrinkage,higher temperature resistance and it is flexible.

3.Application of addition cure liquid silicone rubber
G-830 silicone rubber is flexbile silicone rubber ,it has a higher temprature resistance and lower shrinkage, so it is suitable to make the silicone gasket for machine sealing .

Using instruction

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.
Pour catalyst into the plastic container, noting weight of material poured.
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.
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.
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.
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.
Allow the mold to sit, undisturbed, for at least 4 hours to ensure the silicone is fully cured.
Remove the mold from the frame.
Cut around the pattern carefully to release it from the silicone rubber mold.
