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

Note: This is a 100A:3B mix ratio product that must be measured by weight. 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.
