high quality moulding silicone for concrete mold making


Production Flow


Product Description

1. Description of high quality moulding silicone for concrete mold making

C835 liquid silicone rubber is condensation cure silicone rubber for mold making. The liquid silicone rubber will be cured under room temperature. It's two components, the mixing ratio is 100:2. Part A is a flowable liquid silicone, Part B is the catalyst. It has an exceptional fluidity and good operability.


2. Characteristics of high quality moulding silicone for concrete mold making

* An exceptional fluidity and good operability, easy to demold
* Good tensile strength and tear strength
Suitable hardness
* Copy detailed pattern 
* Good flexibility


* Long shelf-time &lifetime


3Application of high quality moulding silicone for concrete mold making

 C835 liquid silicone rubber is perfect molding material, it is suitable to make mold for concrete casting, artificial stone, brick, cement casting, gypsum decorations, plastic product, resin craft, polyester, polyurethane, bronze casting, statues, jewelry, wax, crystal, tire mold, shoe mold, clay casting, ceramic casting. etc.

C835 liquid silicone rubber is mainly suitable for small or middle sized products with delicate pattern by pouring and brushing operation.

5. Using instructions of high quality moulding silicone for concrete mold making

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.
