tin cure silicone for plaster crafts

Applications of tin cure silicone for plaster crafts:

Tin cure silicone for plaster crafts is mainly applicable to manual mold design, PVC plastic molds, cement product molds, melting point alloy molds, alloy toy craftworks, plastic toy craftworks, gifts and stationery, large statues, duplication of cultural relics, shoe sole mold fabrication, pad printing positioning, shock resistance for electronic equipments, etc

Features of tin cure silicone for plaster crafts

1. Good characteristics of easy-operation

2. Ligh viscosity and good flowability

3. Low shrinkage

4. Favorable tension

5. No deformation

6. High temperature resistance, acid and alkali-resistance and ageing resistance

Why does the tin cure silicone for plaster crafts mould appear to be dry outside but wet inside?

Because molding silicone rubber is a kind of condensation silicone rubber, which get solidified after absorbing moisture from the air. In order to provide a significant shelf-life for the silicon rubber, we will dry out the water in the silicon rubber.

Solution: Add 0.05% water into the silicon rubber and Stir over a low speed briefly when you use it.

Limitations of RTV-2 silicone rubber:

1. When the hardness of RTV-2 silicon rubber is lower than 15 shore A, the tension, the tear strength, the ageing resistance, acid and alkali-resistance of silicon rubber will reduce respectively. 
2. When the hardness of RTV-2 silicon rubber is higher than 50 shore A, the tension and the tear strength of silicon rubber will reduce, and the solidified silicon mold will be easily broken.
