RTV2 stands for "Room Temperature Vulcanizing", meaning it cures at room temperature. The "2" in RTV2 indicates that the product is two-component, consisting of a base material and a catalyst (hardener).
RTV2 mold silicones are categorized into two curing types:
- Addition Cure RTV2 Silicones
- Condensation Cure RTV2 Silicones
What Are Addition and Condensation Cure Silicones?
- Addition Cure RTV2 Silicones: These silicones cure with platinum-based catalysts. They feature various Shore hardness levels (softness-hardness) and offer benefits like complete transparency, oven curing, low shrinkage, and hypoallergenic properties.
Applications of Addition Cure RTV2 Silicones:
- Transfer printing
- Jewelry mold making
- Medical products
- Electronic encapsulation
- Mold making from human skin
- Food-safe mold production
- Automotive spare parts manufacturing
- Prototyping
- Hyper-realistic sculpture making
- Special effects and prosthetic makeup
- Condensation Cure RTV2 Silicones: These silicones cure with tin-based catalysts. They also come in various Shore hardness levels and are used in diverse applications depending on their properties.
Applications of Condensation Cure RTV2 Silicones:
- Accessories
- Shoe soles
- Sanitary ware
- Art
- Soap, candles, and scented stones
- Transfer printing
- Curtain accessories
- Construction and building
- Furniture and interior decor
- Electronic encapsulation
- Buttons
How to Identify High-Quality RTV2 Mold Silicone?
RTV2 mold silicones are widely used for replication and duplication processes due to their ease of use and compatibility with various casting materials. Here’s how to identify a high-quality RTV2 mold silicone:
- Low Viscosity: The silicone should be fluid and easy to pour during application.
- Non-Adhesive: It should not stick to the surface or model being cast.
- High Tear and Tensile Strength: Ensures durability during repeated use.
- Heat and Chemical Resistance: Allows for a high number of casts and long-lasting performance.
- Low Shrinkage and Quick Curing: Maintains accuracy and reduces production time.
- No Residue or Oil Separation: High-quality silicone should not leave residue or secrete oil.
Applications of RTV2 Silicone Rubber
RTV2 silicone rubber is compatible with a wide range of casting materials such as polyester, plaster, polyurethane, wax, soap, scented stones, epoxy, chocolate, and fondant. It is widely used across industries, including automotive, food, giftware, and construction.
Here are some common applications:
- Giftware and Jewelry: Ideal for creating molds for unique designs and detailed models.
- Soap, Candles, and Scented Stones: Frequently used in hobby and DIY sectors.
- Construction and Interior Design: Suitable for wall decorations, restoration projects, and moldings.
- Sculptures and Figurines: Enables easy replication of intricate details.
- Special Effects and Prosthetics: Used for lifelike molds and plastic makeup applications.
- Industrial Applications: Preferred in textile, automotive, and electronics industries for manufacturing machine parts.
- LED Applications: High transparency and non-yellowing properties make it ideal for LED lighting.
- Transfer Printing: Transfers pad printing ink to materials accurately.
