China manufacturer mold making liquid silicone rubber for grc gfrc moulding
Grc & gfrc molding silicone
1. Description
Grc/gfrc is a new kind of material used today for home decor items as well as ornamental moldings.
Gc silicone manufactures two-component, room temperature curing silicone mold materials that are used widely in the grc/gfrc casting industry to create highly detailed decorative parts.
Grc/gfrc 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-825/c-830 for these applications. A tin-cured silicone rubber with a 100a:3b mix ratio; measure with a digital scale.
We manufacture and supply figurines molding silicone rubber, sculpture molding silicone rubber, foundry molding silicone rubber, art casting silicone rubber, foundry casting silicone rubber, etc with best quality and price in china.

Architectural Molding Silicone
Product No.: C-825 and C-830
Brand: GuoChuang Silicone
Application: Making molds for brackets, panels, cornice moulding, statuary etc.
Keyword: mold making silicone rubber, rtv2 silicone rubber, liquid silicone rubber,s liquid silicone for molding
1. Description
Architectural Reproduction and Restoration specialists use GC liquid mold silicone rubbers to make site molds of aging/damaged ornate architectural elements (e.g., brackets, panels, cornice moulding, statuary). From these molds, reproductions of damaged elements can be cast in the controlled environment of a mold shop. These imperfect castings are resculpted to their original beauty so a rubber production mold can be made from this revised model. This production mold allows repeated casting of the new architectural element in concrete, glass fiber reinforced concrete, plaster, plastic, fiberglass, or other casting media as required for interior or exterior mounting.
C-825/C-830 room-temperature curing silicone rubber are popular mold materials for this application and are available in pourable, brushable and sprayable options.
C-825/C-830 is A tin-cured silicone rubber with a 100A:3B mix ratio (digital scale required to measure) and a demold time of 3-4 hours. Tin-cured silicones are slightly less expensive than platinum-cured silicones, but have a shorter library life and shrink slightly on cure.

China liquid Silicone mold making material for concrete/artificial stone casting
Artificial Stone & Concrete Casting Silicone Rubber
1. Description
C-825/C-830/C-835 Silicone Rubber is a two-part, tin-catalyzed, liquid silicone system that cures (RTV) to a white, Shore A25-A35 rubber. This is a pourable rubber, but it can be easily thickened with Liquid Thickener or for brush-on application.
Popular product options is C-825/C-830/C-835 are the mold material of choice for high-volume veneer stone production (manual or automated manufacturing). These two-component mold rubbers capture excellent surface detail, offer exceptional dimensional stability and have unmatched lifetime and durability compared to hot melt and polypropylene systems.
Molds made from these room temperature curing systems can be completed in a much shorter timeframe (~4 hour demold) compared to latex rubber molds. When properly maintained, these molds can last for years and produce thousands of stones.
2. Technical Datasheet
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.

Operation Method:
Both pouring and brushing operation methods for our artificial stone casting silicone are available. You can choose the best one as your preference, we can provide thixotropic agent for brushing.
Notice
What is the hardness should I choose?
Normally 20~40 Shore A will be the best, but it also should according to your size and pattern design.
Warm Tips:
The surfaces with which the material comes in contact must be perfectly clean, free of grease and dry.
Close the bottles after use so as not to confuse the cap of the catalyst with that of the base when re-sealing.
Be aware of possible cross-contamination; it's highly recommended to use only dedicated gear when processing poly-addition RTV2 silicone rubber (including degassing devices).
Be aware that contact with certain material can inhibit the curing of the RTV2 poly-addition silicone rubber. Common contaminants to be avoided include:
-Natural or synthetic rubber, vulcanized with sulphur derivatives.
-Poly-condensation RTV catalyzed with metallic salts.
-PVC stabilizing agents.
-Amine cured epoxies.
-Sulphur, tin and amines derivatives.
-In case of doubt, carry out a small test by pouring the mixture onto a small area of the object.
