Introduction of RTV Silicone for Concrete StoneMold Making
MC RTV Silicone for Concrete Stone Mold Making is a kind of two-component material, that is the moldmaking silicone rubber is made up of Part A base silicone and Part B CA30 curing agent. The mixed Part A base silicone and Part B curing agent can cure at room temperature by a condensation reaction, and the become a siliconer rubber mold that can be used for objects reproduction. These RTV-2 silicone rubber molds can be cast into different material for your target objects.
Characteristics of RTV Silicone for Concrete Stone Mold Making:
1. Good flow ability and long working time
2. Medium hardness
3. High tear and tensile strength
4. Easy de-mould from complex replica parts
5. Acid and alkali-resistance
6. Low linear shrinkage
Applications of RTV Silicone for Concrete Stone Mold Making:
MC RTV Silicone for Concrete Stone Mold Making can be applied in the reproduction of cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. etc.
Instructions of RTV Silicone for Concrete Stone Mold Making
1. Make sure the surface of the original is clean and free of loose material.
2. Weight 100 Part A base and 2 parts of CA30 Curing Agent in a clean container.
3. Stir Part A base silicone before use thoroughly, as filler separation may occur upon prolonged storage.
4. Mix Part A and Part B evenly until the CA30 completely dispersed in the base.
5. Pour the mixed Part A base silicone and CA-30 curing agent as soon as possible onto the original
6. De-mold after 24 hours, it is will improve the replicate times of silicone mold.
Package of RTV-2 molding silicone rubber:
Part A base silicone: 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 800g/bottle, 1kg/bottle
