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.

Moldix® c52 series silicones are brushable tin cure silicone developed especially for casting cultural relics, flowerpot, fountain, plaster, candles, resin and other old architectural restoration products with complex pattern in details, which can protect the mother board. Making a silicone mold by brushing way can reduce the cost of molding material and an external mold (can be gypsum or fiberglass) is required for supporting the silicone mold. Moldix® c52 series already features in high tear strength and durable mold life. However, if you have extra high requirements for 5kg/drum, 25kg/drum, 200kg/drum

Introduction of rtv 2 molding silicone rubber: 1. Two-part of rtv 2 molding silicone rubber: flowable liquid silicon and catalyst. 2. Rtv 2 molding silicone rubber cures at room temperature within 4-6 hours. Features of rtv 2 molding silicone rubber: 1. Rtv 2 molding siliconerubber has an exceptional fluidity and good operability. 2. Rtv 2 molding silicone rubber hasgood temperature and deformation resistance as well as low shrinkage. 3. Rtv 2 molding siliconerubber has high duplication times. Operation step for rtv 2 molding silicone rubber: 1. Step one to use rtv 2molding silicone rubber: take 100g of part a and add 2g of part b and mix thesilicon rubber and the curing agent evenly. 2. Step two to use rtv 2molding silicone rubber: vacuum pumping 3. Without exception, thistakes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available. 4. Step three to use rtv 2molding silicone rubber: brushing cast & perfusion molding operation. 25kgs/drum vacuum package or 200kgs/drum
Applications of manual mold silicone rubber Manual mold silicone rubber is mainly used for model design of manual mold, cement products, low melting point alloy molds, alloy toys, plastic toys, electronics, handicrafts, stationery, large-scale sculpture, reproduction of cultural relic, pad printing allocation, electronic equipment antivibration, and so on. Features of manual mold silicone rubber Manual mold silicone has good elasticity, non-deformation, high temperature resistance, low shrinkage. And it is suitable for manual mold design and small duplication mold production. FAQ of manual mold silicone rubber Why is the manual silicone mold oily? The molding silicone rubber itself doesn contain any oil, so it won be oily. If the mold is oily, it may be because you add the compound silicone oil, which contains silicon oil and white oil. For getting further information about our silicone rubber, Please feel free to contact with Miss Shameya. She can speak good Arabic and English and Chinese for an easier communication with you.
