Mold making silicone rubber for gypsum ceiling
1. Mold making silicone rubber for gypsum ceiling applications:
RTV Rubber Silicon for Plaster Casting Ceiling is primarily intended for poly resin crafts, PU crafts, PU resin crafts ,gypsum crafts , gypsum column ,unsaturated resin crafts, lighting and candles crafts ,plastic toy , stationery gifts crafts industry, a large statue Buddha, relievo furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-scale cement mold, artificial fossils Factory, Europe component factory, simulation landscapes, animals and plants sculpture, sandstone crafts and so on.
2. Mold making silicone rubber for gypsum ceiling 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 demold, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed.
(Note: our company does not recommend you to add silicone oil. If a special soft silicone mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demould.)
As a professional manufacturer of molding silicone rubber, we can provide you the best quality silicone rubber with competitive price and free demold technology.

4. FAQs of Mold making silicone rubber for gypsum ceiling in the use of the operations:
What should we do when the air bubbles appeared in the process of mold making ?
To handle this situation depends on different cases. Under the condition of an available vacuum pumping machine, mix the silicone rubber and curing agent evenly and then take it to vacuum chamber to deair. If without a vacuum pumping machine, reduce the amount of the curing agent properly. For example, change the mixing ratio of the silicone rubber and the curing agent from former 4% to 1%-2%. In this way, the pre-crosslinking time of silicone rubber will slow down, so, the air in the mold will be eliminated gradually to reduce the air bubbles.
