1. Description:
C-810/C-815/C-820 Silicone Rubber is a two-part, tin-catalyzed, liquid silicone system that cures (RTV) to a peach, Shore A10-A20 rubber. This is a pourable rubber, but it can be easily thickened with thickener for brush-on application.
Soap&Candles are routinely cast in both rigid and flexible molds. Rubber molds are employed whenever there are detailed shapes or decorative undercuts that cannot be accommodated using rigid molds. These flexible molds permit easy, cost-effective removal of a variety of candle waxes, including soy, beeswax and paraffin.
Popular mold rubbers for candle&soap making is C-810/C-815/C-820 is two-part, room temperature curing silicone mold rubbers are used to cast soaps&candles of different shapes, sizes and textures.

Note: This is a 100A:3B mix ratio product that must be measured by weight. The choosing of suitable hardness should be according to the size and pattern design of the products. 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.
