Description

 

1.Description of high quality RTV-2 mould making silicone rubber

Mold making silicone rubber has two types, one is condensation cure silicone mainly used for making molds of concrete stone, GRC, gypsum decoration, plaster ornaments, fiberglass products, polyester decoration, unsaturated resin crafts, polyresin crafts, polyurethane, bronze, wax, candle, duplicating for industries such as toys, gifts, decoration, plate engrave, human replica, art crafts, resin crafts, poly resin crafts, unsaturated resin crafts, candle crafts, plastic crafts, stationeries, plaster crafts and Buddhist statue crafts and imilar products.

 

Other one is addition cure silicone rubber mainly used for making molds of rapid prototyping and tyre molds; chocolate, candy, cake, artificial limb and human body parts similar products, and also can used for making molds of concrete stone, GRC, gypsum decoration, plaster ornaments, fiberglass products, polyester decoration, unsaturated resin crafts, polyresin crafts, and  similar products.

 

 

 

Application

 

2.The difference between addition cure silicone and condensation cure silicone:

The mixing ratio of A and B is different

The mixing ratio of condensation cure silicone is normally 100:2~100:5, some from European and USA is 10:1.

The mixing ratio of addition silicone is normally 1:1, 10:1, 9:1;

Addition cure silicone is odorless, environmental friendly, and food grade. So the raw material of addition cure silicone is more expensive than that of condensation cure silicone, so does the price.

 

Addition silicone has a wider range of applications, such as used for food, life casting, tire mold casting, human organs, prostheses, breast, sexy toys, life-size dummies, human-like skin and so on.

 

The shrinkage of condensation cure silicone is low, about 0.3%; While addition cure silicone is with lower shrinkage, about 0.1%.

 

Addition cure silicone can be transparent, even high transparent, of course the price is more expensive.

However, condensation cure silicone can be white or other colors too, but no transparent.

 

Temperature resistance is different, addition cure silicone is better than condensation cure silicone in this performance. 

Condensation cure silicone: 100-150C

Addition cure silicone: 150-220C

 

 

Features

 

3.Characteristics of high quality RTV-2 mould making silicone rubber

*An exceptional fluidity and good operability, easy to demold

*Good tensile and tear strength

*Outstanding bubble releasing

*Non-deformation

*Low shrinkage 

*Aging resistance ,high temperature resistance (200℃)

*Environmentally, food-grade

 

4. Normally, different silicone should be chosen according to different product's features, for example 

 

- For products size (20cm-80cm), 

with intricate designs, 20-25 shore A is suitable. 

with simple designs, 25-30 shore A is suitable.

 

- For products size (80cm-150cm), 

with intricate designs, 25 shore A is suitable.

with simple designs, 30-35 shore A is suitable.

 

- For products size (more than 150cm), 

with intricate designs, 25-28 shore a A is suitable.

with simple designs, 35-40 shore A is suitable. 

 

Operation

 

6. Operation instructions of high quality RTV-2 mould making silicone rubber

Step 1: prepare the original molds 

Prepare an perfect original mold and clean it totally before operation .

*Notes:Make sure your original molds and operation tool cleaned up totally to avoid uncure problem .

 

Step 2: Take 100 G part A and 100 G part B (Or 100 G part A and 10 G part B) and mix them evenly. 

*Notes: Addition cure mold making silicon rubber is two part flowing liquid , Pls follow the step strictly:

         1.Weigh the two part exactly by electronic weight.. 

If any part not in exactly weight , it may cause changing of hardness , or even cause uncure problem.

         2.Mix part A and part B evenly. 

Otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. What’s more, the finished molds will meet a short life. All of these will cause a waste of silicon rubber.

Step 3: Vacuum pumping

Without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available. 

 

Step 4: Pouring casting or Brush operation

*Notes:1. For simple pattern products we suggest use pouring operation way , which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air . 

        2.For delicate pattern products we suggest use brushing operation way , which can copy the pattern exactly . Brushable silicone require high viscosity which won’t be easy to flow away and easy to brush .  

        3. We suggest to set the silicone mold for another 12 hours after demould before put into large production .

 

Warm tips of high quality RTV-2 mould making silicone rubber :

1.As addition cure silicone is a kind of platinum cure system ,which will be easy to cause uncure problem ,so 

Kindly follow the tips below :

*Do not mix with liquid condensation silicone rubber or even the tool which used for condensation silicone 

*Do not mix with organic matter which contains N, S, P organics and ionic compound like Sn, As,Hg, Ph,

*Do not add any pigment or powder into the addition cure silicone rubber without any testing to prevent uncure problem
