Applications of Silicone rubber for concrete stone replication:  

Silicone rubber for concrete stone replication is mainly used in toys,gifts,decoration,plate engrave, human replica, art crafts, resin crafts,poly resin crafts,unsatured resin crafts, candle crafts, plastic crafts,stationeries,plaster crafts and Buddhist statue crafts,etc.

Features of Silicone rubber for concrete stone replication:

Silicone rubber for concrete stone replication has good characteristics of easy operation, light viscosity and good flowability, low shrinkage, favorable tension, No-deformation favorable hardness and high temperature, acid alkali and ageing resistance.

Basic description of Silicone rubber for concrete stone replication:

Silicone rubber for concrete stone replication is a kind of silicon consisted with two part, one is silicon another one is catalyst, the ratio is 100:2 under temperature 25°the operating time of mold making silicon is half an hour,demould time 2-4 hours. if customers make molds in brushing way,628 and 638 are good choices as they have moderate viscosity.

Operation of Silicone rubber for concrete stone replication:

If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demold, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed.

(Note: our company does not recommend you to add silicone oil. If a special soft silicone mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demold.)

FAQ for Silicone rubber for concrete stone replication:

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 must demould the product within 3 minutes to avoid this problem.

Packaging, storage and transportation for Silicone rubber for concrete stone replication:

1. This product need to be packed in clean, dry and sealed steel cans or drums. Part A and B need to be packed seperately. Usually it is packed in 5kg/can, 20 kg/drum, or 200 kg/drum . 

2. Please keep the material in a cool and dry place. Specially note that the silicone should not touch or mix with compounds including nitrogen, phosphorus, sulfur, tin, lead or metal organic acid. Otherwise, the catalyst will be poisoned, then the silicone can not be cured or just particially cured. For specific precautions, please refer to the instructions in Electronic Potting Silicone part.
