Silicon rubber for mold making features Silicon rubber for mold making is white or red flowing liquid with general hardness of 22-50a++pafter 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. Silicon rubber for 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 demould, more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed. 25kg/drum, 200kg/drum

How to make the silicone mold? 1. Make sure the surface of the original is clean and free of loose material. 2. Weight 100 Part A base and 2 parts of CA30 Curing Agent in a clean container. 3. Stir Part A base silicone before use thoroughly, as filler separation may occur upon prolonged storage. 4. Mix Part A and Part B evenly until the CA30 completely dispersed in the base. 5. Pour the mixed Part A base silicone and CA-30 curing agent as soon as possible onto the original 6. De-mold after 24 hours, it is will improve the replicate times of silicone mold. Note: It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 mins under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen. Part A base silicone: 20kg/drum, 25kg/drum or 200kg/drum Part B CA30 Curing Agent: 0.25kg/bottle, 1kg/bottle and 10kg/bottle

Free sample rtv2 mould making silicone rubber for Architectural Molding 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. 2.Technical Datasheet Typical general characteristics Inspection MethodValue Product data (Catalyzed A+B)C-825C-830 HardnessShore A25±230±2 Mix RatioA:B100:3100:3 Color/WhiteWhite Pot life25 °C (77F)30-40mins30-40mins Curing time25 °C (77F)3-4 hours3-4 hours Mixed viscositymPa.s20000±100023000±1000 Tear-strengthkg/cm22±223±2 Tensile-strengthM.pa4.0±0.55.0±0.5 Elongation%450±50460±50 Shrinkage%0.30.3

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. 3.
