RTV silicone rubbers advantages
Reusable
* Molds can be used over and over again.
* Does not shrink
* Has good abrasion resistance.
* Comes in a wide range of hardness and therefore gives long mold life.
* Can be poured, brushed or sprayed on to the original model.
* The most economical overall (compared to other mold rubbers).
FAQ for RTV Silicone Rubber:
Why the Mould making silicone rubber mold appear with weak tear strength?
When making silicone rubber mold, some customer add a lot of silicone oil to reduce the viscosity of silicone rubber. In fact, this has the opposite effect. The tension and tear strength will be reduc ed badly with the addition of silicone oil, which leading to the weak and flimsy condition of silico ne rubber molds.
Good deal: buying from seller
