Appilication of RTV liquid molding silicon rubber for toy crafts making
RTV-2 silicon rubber is primarily intended for the mold making of poly resin crafts, PU crafts, PU resin crafts ,gypsum crafts ,unsaturated resin crafts, lighting and candles crafts ,plastic toy , stationery gifts crafts industry, a large statue Buddha, furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-scale cement mold, artificial fossils Factory, Europe component factory, simulation landscapes, animals and plants sculpture, sandstone crafts and so on.
RTV liquid molding silicon rubber for toy crafts making features description
RTV-2 silicon rubber is white or red flowing liquid with general hardness of 22-50A°after curing. RTV-2 silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.
Advantages of nonshrinkage long shelf life silicone for concrete molds :
-low shrinkage (less than 0.1% )
-high tensile and tear strength with high copy times
-easy for operation (mixing ratio at 1:1 /10:1)
-good fluidity easy for pouring operation ( in round 10000 cps )
-it is food grade with FDA

Operation instruction of nonshrinkage long shelf life silicone for concrete molds :
1. Pls clear the model and tool totally before operation to prevent cure inhibition.
2.Weigh the two part correctly by electronic weight in two separate container .
3. Mixing the two part in 1:1/10:1 and stir part A and part B evenly in 2-3 minutes .
4.And get the mixture for vacuum-pumping for de-air the bubble in around 2-3
minutes . (If there is no vacuum machine, pls pour the mixture carefully and slowly
down the side of the mold frame so that less bubbles caused)
5. Enclose the product (the original model) with four plastic plates or wooden plates.
6. Clean your products and brush a layer of release agent(detergent or soap water) on
your product.
7. Pour the vacuumed mixture into the model frame from the side of the mold frame .
Frequently asked questions of molding silicone rubber
Why does the silicone rubber mold have few molding times?
The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
What should we do when the air bubbles appeared in the process of mold making ?
To handle this situation depends on different cases. Under the condition of an available vacuum pumping machine, mix the silicon rubber and curing agent evenly and then take it to vacuum chamber to deair . If without a vacuum pumping machine, reduce the amount of the curing agent properly. For example, change the mixing ratio of the silicon rubber and the curing agent from former 4% to 1%-2%. In this way, the pre- crosslinking time of silicon rubber will slow down, so the air in the mold will be eliminated gradually to reduce the air bubbles.
