Frequently asked questions about RTV silicone equal to Dow corning 3481

Why does the mold making silicone rubber mold have few molding times?

1.adding too much silicone oil which will destroy the molecular of silicone rubber;

 

2.Making the mold for small and detailed patterns products with higher hardness silicone rubber which is easy to break;

  Making the mold for large and simple 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.
