Condensation RTV2 Silicone Rubber For Cornice Molds, Plaster Decorations
Description of condensation RTV2 Silicone Rubber For Cornice Molds, plaster Decorations
RTV2 silicone rubber is a kind of two-component material, that is the mold making silicone rubber made up of Part A base silicone and Part B curing agent. The mixed Part A base silicone and Part B curing agent can cure at room temperature by a condensation reaction,then become a silicone rubber mold that can be used for objects reproduction

USING INSTRUCTION of condensation RTV2 Silicone Rubber For Cornice Molds, plaster Decorations
1- Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
2- vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause , and no more further steps will be available
3- Pouring mold or block mold of silicone rubber
The pouring way is an easy way to make molds, it's slowly and evenly pour into the mixed silicon rubber into the square frame. After the cross linking reaction.

Storage of condensation RTV2 Silicone Rubber For Cornice Molds, plaster Decorations
When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, Silicone Base and Curing agent have a usable life of 10 months from the date of production. After 12 months stockpiles use the Stir to mix the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
RTV-2 silicones are specifically designed to replicate stones, marble, wood, and other construction materials, producing outstanding fidelity for every detail, including veins and surface texture. The various grades of architectural molding silicones enable builders to replicate accurately the look they desire while providing long mold life and excellent resistance against casting materials.
Benefits of MC Silicone of condensation RTV2 Silicone Rubber For Cornice Molds, plaster Decorations
Ease of processing
High resin resistance increasing the number of cast parts
Low linear shrinkage for greater accuracy
Easy release of shapes, including large pieces and complex geometries
High compatibility with water-rich casting materials such as gypsum
Increased compatibility with high performance concrete
Dimensional stability due to very low shrinkage
