Application of Hot sale silicone rubber for cement mold

Hot sale silicone rubber for cement mold is mainly applied for making various molds,such as reproduction of cement,concrete, artificial stone,poly resin, epoxy, polyurethane-polymer, plaster, gypsum casting and molding, soaps, candle & lighting, architecture, decorative  arts and crafts, plastic toy, gift and stationery, big statue, cultural relic product, etc..



Description about Hot sale silicone rubber for cement mold

Silicone rubber for cement mold is Tin-based silicone, also called condensation-cure silicone, is two-component material which cure at room temperature(RTV)to flexible, high tear-strength rubbers. Tin cured silicone can be poured onto models or brushable by adding a thixotropic additive. It is ideal for molds where easy release or high temperature resistance is required. Tin cured silicone can be used for casting polyurethane, epoxy and polyester resins, waxes, all gypsum products and low-temperature metals. Our tin-cured silicone systems are the most economical. They are best used for casting resins and low melt metals.

Operation tips

Operation tips for Hot sale silicone rubber for cement mold

 1. weigh the liquid silicone rubber and curing agent exactly
 2. Stir the liquid silicone rubber and curing agent evenly
 3.we should choose the right hardness to make different size of product mold

 During operation the three important thing to pay attention
a. adding too much silicone oil will destroy the molecular of silicone rubber, which will cause a decrease of the tensile and tear strength of the mold and deformation may occur.

b. remember to take the proper silicone rubber to make the mold for suitable products. for products with delicate and complicated patterns, you are expected to use soft silicone to make molds. While for products with easy and smooth patterns, you should choose hard silicone rubber.

Plus: We have free CD on how to operate for our customers enclosed with product package.


Frequently asking question about molding silicone rubber

1.Why will the silicone mold be reused only for a few times?

a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which can destroy

the molecular weight of silicone rubber and reduce the tension and tear strength.

b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs or the silicon rubber with a low hardness to makes molds for large sized products with simple designs.


2.Why does the silicone mold get burnt out?

This consequence happens only because you have left out the important notes when using unsaturated resin materials to produce your products. The unsaturated resin produces great heat when added the curing agent. So you demould the resin product within 3 minutes can avoid this problem.


3.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.


4. Why does the silicone rubber molds appeared striated and not smooth?

It is because the appearance of the product or the model itself is not perfect, and it has not been polished before the further operation. So when you make silicon molds, firstly you should polish the product, spray the mold spray evenly on the product. In this case, the problem can be avoided.
