Detailed Description
Tin cure liquid molding silicone rubber for plaster casting cornice mold
Plaster Ornamentation Molding silicone
1. Description
Plaster is an age-old casting media used today for casting statuary, home decor items (e.g., lamps, wall plaques) as well as ornamental moldings and decorative millwork.
GC Silicone manufactures two-component, room temperature curing silicone mold materials that are used widely in the plaster casting industry to create highly detailed plaster parts.
Plaster can be cast repeatedly into silicone molds without release agents. The primary differences between polyurethanes and silicones are the cost (silicones are more expensive than polyurethane) and the range of hardness available within the product lines. For highly detailed and delicate castings, silicone rubbers may be necessary as they are available in softer and more flexible options compared to polyurethanes.
The popular silicone mold rubber is C-820/C-825 for these applications. A tin-cured silicone rubber with a 1A:10B mix ratio; measure with a digital scale.
Guochuang Silicone manufacture and produce custom rtc-2 silicone, addition cure silicone rubber, silicone for mold making. Our platinum cure silicone rubber, liquid silicone rubber for sale.

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.
