RTV Silicone Rubber Features:
RTV silicone rubber is white or red flowing liquid with general hardness of 22-50A°after curing.RTV silicone 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 Silicone Rubber Operations:
RTV silicone rubber with high hardness is suitable for making large products and large size molds. On the contrary,RTV silicone rubber with low hardness is fit for molds of fine and precision patterns. 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 silicone oil. If a special soft silicon mold or fine detailed and complex patterns product is required, 5%-10% silicone oil can be added to soften the mold for easier demould.)
