Attention for making a mold by Rock molds making liquid silicone rubber rtv 2

1. molds making liquid silicone rubber rtv 2 is white flowing liquid with general hardness of 22-40A° after curing.
2. If the mold makers want to make large products and large size molds, the mold should be made of silicone rubber with high hardness. On the contrary, if the products with fine and precision patterns, it should be made of silicon with low hardness.
3. 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.
4. it doesn't better to add silicone oil into silicone rubber. 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. )
