Cleaning and Sterilizing Siraya Tech Defiant Silicone Parts

These instructions apply only to fully cured Siraya Tech Defiant silicone molds. Do not attempt to heat the liquid silicone components (Part A or Part B).

The Defiant silicone series is rated for temperature resistance up to 200°C (392°F), making it suitable for sterilization with boiling water or steam. This process is effective for applications requiring high levels of cleanliness, such as making molds for food products

Step 1: Initial Cleaning

Before sterilizing, you must clean the part to remove any residual casting material, oils, or surface debris.

  1. Wash: Gently wash the silicone part using warm water and a mild dish soap. Use a soft sponge or cloth to avoid damaging fine details in the mold.

  2. Rinse: Rinse the part thoroughly with clean, warm water to remove all soap residue.

  3. Inspect: Check the part to ensure all physical contaminants have been removed before proceeding to sterilization.

Step 2: Sterilization (Choose one method)Method A: Boiling Water Sterilization

This method is simple and effective for general and food-safe applications.

  1. Submerge: Place the cleaned silicone part in a pot. Fill the pot with enough water to fully submerge the part.

  2. Boil: Bring the water to a rolling boil.

  3. Sterilize: Allow the part to remain in the boiling water for 5-10 minutes. Because Defiant silicone can resist temperatures up to 200°C, it will not be damaged by boiling water (100°C).

  4. Remove: Carefully turn off the heat and use tongs or other appropriate tools to remove the hot part from the water.

  5. Dry: Place the part on a clean, dry surface or paper towel and allow it to air dry completely. Ensure it is fully dry before storage or its next use to prevent any moisture retention.

Method B: Steam Sterilization (Autoclave)

This method is suitable for industrial or professional settings requiring a higher level of sterilization.

  1. Preparation: Place the clean, rinsed part inside the autoclave.

  2. Cycle: Run a standard steam sterilization cycle appropriate for silicone parts (typically at 121°C or higher). The high-temperature resistance of Defiant silicone makes it compatible with common autoclave cycles.

  3. Cool & Dry: Allow the autoclave cycle to complete, including the cooling and drying phases.

  4. Remove: Once the cycle is finished and the machine indicates it is safe, remove the sterilized part. Ensure it is completely dry before use or storage.
