Tin Cured Silicone For Stone Mold/GRC Casting

Tin Cured Silicone For Stone Mold/GRC Casting      Advantages of Tin Cured Silicone For Stone Mold--- Advantages - High fluidity -Shelf life:1.5 year - Excellent reproduction of details -  we promise non-oily - Low linear shrinkage -  catalyst: environmental,non smell - Good release properties with organic resins and gypsum         Introduction of Tin Cured Silicone For Stone Mold-- Tin Cured Silicone For Stone Mold is a low viscosity, two-part condensation cure silicone rubber. It is used for mould making where it is mixed (with its catalyst) and then poured around a pattern to create a flexible silicone mould. Tin Cured Silicone For Stone Mold has been specially selected for its ease of use, excellent performance and great value.
Once cured the silicone rubber is very soft and flexible making it perfect for casting complicated or intricate shapes where the cast part can be easily removed from the silicone mould.          Datesheet compare with other famous brand---

      Suggested Uses---
The cured mould can then be used to produce precise replicas of the original part, including fine surface detail, out of a range of materials including polyester, epoxy and polyurethane resin, urethane foam, wax, casting plaster, Jesmonite, and reconstituted stone.         FAQ--- Why is the tear strength of the silicone mold weak? In order to reduce the viscosity of silicone rubber and pursue a good quality, you may add a lot of silicone oil into the silicone rubber when making molds. In fect, it might have just the opposite effect. The tension and tear strength will be reduced badly with the addition of silicone oil. And the silicone molds will be ina weak and flimsy manner.         Packing view---       Company Information---       Fore more information for Tin Cured Silicone For Stone Mold, pls contact Iris..
