How should I prepare the original surface for molding?

The original surface must be clean and free of loose material. For porous substrates or thin patterns, apply a mold release agent such as soap water, detergent, Vaseline, or petroleum jelly.

What is the tensile strength of this silicone rubber?

The tensile strength is 3.8 MPa, and the tear strength is 30 n/mm, providing good durability for repeated use.

Product Q&A

Q:What is the mixing ratio for Part A and Part B?

The standard mixing ratio is 100 parts of Part A base silicone to 2 parts of Curing Agent (CA30). This can range from 100:2 to 100:5 depending on desired curing speed.

Q:How long does it take for the silicone mold to cure?

The material cures to a flexible rubber within 4-6 hours at room temperature. It is recommended to demold after 24 hours to improve the mold's replication lifespan.

Q:What materials can be cast using this silicone mold?

This silicone mold is suitable for casting plaster, polyurethane (PU), GRC, cement, resin, polyester, wax, and other similar materials.

Q:Is the silicone rubber customizable?

The product description lists specific attributes such as color (off-white), hardness (28-30 Shore A), and mixing ratio. It does not explicitly state that these attributes are customizable.

Q:What are the packaging options?

Part A is available in 20kg/drum, 25kg/drum, or 200kg/drum. Part B is available in 0.8kg/bottle or 1kg/bottle.
