2.making the mold for large products with soft RTV-2 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 silicon rubber to make the mold for suitable products.
1.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 silicon rubber which is easy to break;
The RTV-2 silicone rubber mold has few molding times is due to follwoing reasons:
Why does the RTV-2 silicone rubber mold have few mold times?
Frequently asked questions of RTV-2 silicone for mold making
(Note: our company does not recommend you to add silicone oil. If a special soft silicon mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demould.)
If RTV-2 silicone rubber molds requiring fast drying and demould, more curing agent is needed; contrarily, if RTV-2 silicone rubber molds requiring slower drying and demould, less curing agent is needed.
On the contrary, if the mold with fine and precision patterns, the RTV-2 silicone mold should be made of silicone with low hardness. The amount of the curing agent depends on the actual requirements of the customer.
If the customer wants to make large products and large size molds, the mold should be made of RTV-2 silicone rubber with high hardness.
