[1] Casting Silicon for Making Molds application
Casting Silicon for Making Molds mainly applicable to make the silicone mould for cultural relic duplication, architectural decoration, resin crafts, lighting ornaments, statues, prefabricated concrete, rosettes, cornices, fountains and garden articles, sanitary fixtures, decorative pottery, giftware, industrial equipment, decorative candles, gaskets, mechanical components, but also soles for footwear, archaeological findings or automotive prototypes.
[2] Casting Silicon for Making Molds features:
Casting Silicon for Making Molds are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2-3% curing agent, they can still be operated within 30 minutes, but will be formed after 2-3 hours. With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poli crafts, resin crafts lighting and candle crafts.
