Customer Questions & Answers
-
Question:
What is THI-VEX and how does it work?
Answer: THI-VEX is a thixotropic agent formulated specifically for thickening Smooth-On silicone rubbers. It alters the viscosity of silicone materials, allowing them to hold their shape and resist flow under certain conditions. This property is especially beneficial when creating intricate molds or working with vertical surfaces, as it prevents drips and uneven application. -
Question:
In what applications can I use THI-VEX?
Answer: THI-VEX is ideal for a variety of applications in casting and mold making, particularly for artists and fabricators. It can be used in creating sculptural works, special effects, and prototypes where a thickened silicone rubber is necessary. This allows for detailed features and precision work without worrying about the material running or sagging. -
Question:
What is the recommended amount of THI-VEX to use with silicone rubbers?
Answer: The recommended amount of THI-VEX to use typically ranges from 1% to 5% of the total silicone rubber weight. Start with a smaller amount, mix thoroughly, and adjust as needed based on your desired consistency. This flexibility allows you to achieve the perfect thickness for your project, ensuring better handling and application. -
Question:
Is THI-VEX compatible with all silicone products?
Answer: THI-VEX is specifically designed for Smooth-On silicone rubbers and is best used with their products. While it may not yield the same results with other brands, compatibility can vary. Always conduct a small test batch when using a new material to verify that the desired properties are achieved before committing to a larger project. -
Question:
How do I mix THI-VEX with silicone rubber?
Answer: To mix THI-VEX with silicone rubber, measure the appropriate amount of silicone and THI-VEX, then combine them in a mixing container. Stir slowly to avoid introducing bubbles into the mixture, ensuring a uniform consistency. Thorough mixing is crucial for optimal performance and thickening efficiency, leading to better results in your applications. -
Question:
Can THI-VEX affect the curing time of silicone rubbers?
Answer: THI-VEX may slightly influence the curing time of silicone rubbers, depending on the amount used and other formulation factors. Generally, thickening does not dramatically alter curing dynamics, but consider this when planning your project timeline. It's advised to monitor your material closely during the curing process, particularly when using high concentrations. -
Question:
Is THI-VEX safe to use?
Answer: THI-VEX is generally considered safe when used according to the manufacturer's instructions. It's recommended to wear gloves and work in a well-ventilated area to minimize exposure. Always refer to the Safety Data Sheet (SDS) for specific safety precautions, ensuring a safe working environment while creating with silicone rubbers. -
Question:
What tools do I need to use with THI-VEX?
Answer: When using THI-VEX, you'll need basic tools such as a digital scale for accurate measurements, mixing cups, and stirring sticks. Additionally, consider using gloves and protective eyewear to ensure safety during handling. These tools facilitate a smooth mixing process and proper application of the thickened silicone, contributing to a successful project. -
Question:
Can I use THI-VEX for larger projects?
Answer: Yes, THI-VEX is suitable for both small and large projects. For larger applications, simply scale up the amount of silicone and THI-VEX proportionately while maintaining the recommended mixing ratio. This versatility makes it ideal for a range of applications, from small craft items to larger sculptures and prototypes. -
