Product Description

1. RTV silicone rubber for plaster molding Application:

For making molds for plaster moldings, plaster cornice, plaster column, ceiling medallion, ceiling roses, ceiling centres, ceiling panel, paster corbels, plaster friezes, etc. It can also be used for other materials like resin, candle, wax, cement, fiberglass, etc., based on different size ,patterns and your operation method.

2. Liquid silicone for plaster molding Features:

Liquid Silicone for plaster molding is white flowing liquid with general hardness of ****0A° After curing. Molding silicon 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.

3. Liquid silicone for gypsum colum mold making 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%**0% silicone oil can be added to soften the mold for easy demould. )

4. Frequently asked questions of mold making silicone rubber RTV2:

Why does the silicone rubber mold have few molding times?

The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
