5. Using instructions of food grade liquid silicone rubber for making mould
Step 1: Prepare and clean the prototype.
You must make sure your original molds perfect, fix the original mold on a board, then using some assistant material (like cardboard) to make a frame for to surround the prototype. The frame is no need, if we make the mold by brushing way.
Step 2: Take the silicone and catalyst as the ratio 100:2 (silicone : catalyst= 100:2), mix the silicone rubber and catalyst evenly.
Notes: rtv silicone rubber is a kind of flowing liquid and it contains two parts. Part A is a kind of flowing liquid and part B is the curing agent. Remember to mix part A and part B evenly, otherwise the silicone rubber will be partly solidified and this will bring troubles for your final operation. What's more, the finishes molds will have a short life. All of these will cause a waste of silicone rubber.
Step 3: Vacuum pumping.
After mixed the silicone evenly, it is better to release the bubble by vacuum pumping.
Step 4: Pouring cast or brushing cast.
After released the bubble, we can pour/brush the silicone rubber on the prototype.
Notes: Please finishes all the steps within the operation time. If not, it will cause cross linking reaction, and no more further steps will be available. So, we have to pay attention to the pot life and curing time.

Notice
What is the hardness should I choose?
Normally 20~40 Shore A will be the best, but it also should according to your size and pattern design.
Warm Tips:
The surfaces with which the material comes in contact must be perfectly clean, free of grease and dry.
Close the bottles after use so as not to confuse the cap of the catalyst with that of the base when re-sealing.
Be aware of possible cross-contamination; it's highly recommended to use only dedicated gear when processing poly-addition RTV2 silicone rubber (including degassing devices).
Be aware that contact with certain material can inhibit the curing of the RTV2 poly-addition silicone rubber. Common contaminants to be avoided include:
-Natural or synthetic rubber, vulcanized with sulphur derivatives.
-Poly-condensation RTV catalyzed with metallic salts.
-PVC stabilizing agents.
-Amine cured epoxies.
-Sulphur, tin and amines derivatives.
-In case of doubt, carry out a small test by pouring the mixture onto a small area of the object.

China liquid Silicone mold making material for concrete/artificial stone casting
Artificial Stone & Concrete Casting Silicone Rubber
1. Description
C-825/C-830/C-835 Silicone Rubber is a two-part, tin-catalyzed, liquid silicone system that cures (RTV) to a white, Shore A25-A35 rubber. This is a pourable rubber, but it can be easily thickened with Liquid Thickener or for brush-on application.
Popular product options is C-825/C-830/C-835 are the mold material of choice for high-volume veneer stone production (manual or automated manufacturing). These two-component mold rubbers capture excellent surface detail, offer exceptional dimensional stability and have unmatched lifetime and durability compared to hot melt and polypropylene systems.
Molds made from these room temperature curing systems can be completed in a much shorter timeframe (~4 hour demold) compared to latex rubber molds. When properly maintained, these molds can last for years and produce thousands of stones.
2. Technical Datasheet
Note: This is a 100A:3B mix ratio product that must be measured by weight. The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise.

Instruction for using silicone rubber for mold making to make molds.
Step 1:preparing mold.
Once you have your model to mould you need to build a box from wood/acrylic to contain the silicone and get a good covering over your model , the size and shape of this container is totally depends on shape of the model , remembering to leave plenty room surrounding the model so that you will have a strong wall thickness (at least 20mm)
Note:small models can be cast in sourced containers like tins , ice buckets , cake tins, etc

WSD-302AB is two components of silicone adhesive , it is fast-cure type glue for cured silicone rubber bonding with cured silicone rubber at high temperature.
Silicone soft touch smooth feeling oil is also called silicone matting oil, silicone matte oil, etc. It is mainly used for coating silicone-based products. Because of silicone products molded out of the surface are rugged and wrinkled, feeling bad while touch it, generally by spraying soft touch smooth feeling oil to improve the silicone surface effect, make it have have a delicate and smooth feelings, and increase products additional value and selling point.
PTC-200A/B is a platinum catalytic vulcanizing agent for molding and hot air vulcanization of compounded silicone rubber, and the vulcanized products are odorless, non-toxic, and anti-yellowing. When used for molded products, it can achieve fast vulcanization at about 110-130â?? (measured mold temperature), and at the same time, it has a relatively long waiting time at room temperature after refining.
platinum vulcanizing agent is really an effective alternative to the double two five vulcanizing agent, and more efficient, more environmentally friendly, saving the overall cost!
C-20 anti-yellowing vulcanizing agent, is a mixture of peroxide and raw rubber carrier, also used in silicone products molding vulcanization process, used in high-quality products for long-term use, used for transparent, semi-transparent and white, semi-transparent color and other products to prevent yellowing phenomenon, in the transparent or white parts, to ensure that high temperature vulcanization for many times (or the second vulcanization of 200 â?? for about 4 hours of baking), the product does not turn yellow, applicable to the color of pieces of anti-yellowing, to ensure that the color of colored parts do not turn yellow after many times of vulcanization, as well as long-term use of the color does not change color!
C-14 odorless vulcanizing agent, with excellent dispersion, fast vulcanization speed and odorless vulcanized silicone products, is suitable for crosslinking of vinyl silicone rubber, polyethylene and ethylene propylene rubber.
It is importantly used in food grade silicone products, kitchen products and baby products.
