rtv vs silicone applications
rtv vs silicone is intended for for artificial stone mold making architectural decoration, funiture decorative, sculpture, and so on.
rtv vs silicone features
rtv vs silicone is flowing liquid with general hardness of 22-50 A° after curing with features:
1. rtv vs silicone withresistance to deformation and high-temperature, acid-alkali and expansion
2. rtv vs silicone with good tensile strength, tear strength and elongation
3. rtv vs silicone with high reproduction times
rtv vs silicone operations
If customers want to make large products and large size moulds, the mould should be made of silicon rubber with high hardness. On the contrary, if the mould 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 mould requiring fast drying and demould, more curing is needed.
(Note: our company does not recommend you to add silicon oil. If a special soft silicom mould or fine detailed and complex patterns products are required, 5% - 10% silicon oil could be added to soften the mould for easy demould.)
