The brief descripsions about the RTV silicone rubber

RTV silicone rubber  is a white or red flowable liquid with a hardness of 22—50A° when cured. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise.
