RTV-2 molding silicon features
RTV-2 molding silicon is white or red flowing liquid with general hardness of 22-50A° After curing. Molding silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.
RTV-2 molding silicon 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 demould, more curing agent is needed; Contrarily, if molds requiring slower drying and demould, less curing agent is needed.
(Note: Our company does not recommend you to add silicon 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. )
Frequently asked questions of RTV-2 molding silicon
Why does the RTV-2 molding silicon have few molding times?
The RTV-2 molding silicon has few molding times is due to follwoing reasons:
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 silicone rubber which is easy to break;
2. 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.
