1.Description of rtv2 food grade platinum cure silicone rubber for cake candy mold making

SP-820 silicone is addition cure silicone rubber with food grade for chocolate mold. The silicone rubber will be cured under room temperature and can be cured fastly by heating, It’s two-components food grade 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 food grade.

3.Application of rtv2 food grade platinum cure silicone rubber for cake candy mold making

It has 2 main parts application:

First: making many kinds of molds:

*Making molds for: 

                         Low melt metals (mold life can be short) 

                         Cement, Concrete  

                      concrete stones

                         wax molds

                         PU molds

                         resin molds  

 gypsum casting

                         candle molding 

                         chocolate , candy and any other FDA food product mold making

                         prototyping etc.

 

*Making molds for food grade products: chocolate molds, cake molds, sugar molds,ect.

*Making molds for life casting: real hand molds, real feet molds, dildos molds, sex doll molds, ect.

 

Second: make silicone products, like silicone insoles, silicone gel, ect.

and  prosthetics arms,  prosthetics hands,  prosthetics foot,  prosthetics legs, ect.

and silicone mask, skin, ect. sex dolls, sex toys, ect.

Using instruction

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.
