RTV-2 silicone rubber for artificial stone molding

Features of silicone rubber for artificial stone molding :
1 .Two part of Silicon rubber for artificial stone products: liquid white silicone and curing agent.
2. Silicon rubber for artificial stone products Cure at room-temperature within 4-8 hours, but all performance will act perfectly when it cure within 24 hours.
3 . Silicon rubber for artificial stone products has Good fluidity and excellent operation.
4 . Silicon rubber for artificial stone products has Good resistance to weather, temperature, aging, acid..
5 . Silicon rubber for artificial stone products has Excellent tear strength, comfortable duplication times.

Silicone rubber for artificial stone molding operations:

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.) 

Frequently asked questions of Silicone rubber for artificial stone molding:

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.
