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.

* Description
SVR CV50 is a constant viscosity grade. It is made by adding hydroxylamine neutral sulfate (HNS) and peptizer before coagulation with acid. The coagulum is allowed to mature some hours, reduced to crumbs by passing through a crusher, crepers, a shredder, dried and pressed into bales. The hydroxylamine inhibits the storage hardening reaction in natural rubber, which leads to an increase in its Mooney viscosity. Mooney vicosity (MV) is 50 ± 5.
