RTV2 mold silicone is widely used across various industries, enabling effective replication systems for multiple applications. Its ability to save time has made RTV2 mold silicone an indispensable material for manufacturing companies. In this article, we’ll walk you through how to properly use RTV2 mold silicone and its application areas. Let’s explore the steps to get the best results from RTV2 mold silicone.
Step-by-Step Guide to Using RTV2 Mold Silicone
1. Clean the Surface (Model)
Before pouring silicone, ensure the surface is clean and free of:
Dust
Dirt
Moisture
2. Apply a Suitable Mold Release Agent
A mold release agent ensures smooth separation of the mold from the model. Application methods include:
Spray
Brush
Sponge
3. Pre-Mix the Silicone
Before adding the catalyst, mix the silicone for at least 30 seconds.
This enhances the silicone’s flow properties.
It ensures the chemical components within the silicone are evenly distributed.
4. Prepare for Casting Without Delays
Once preparations are complete, proceed with the casting promptly.
Add the appropriate amount of hardener to the silicone.
The ideal curing time is 8-12 hours. Silicone that cures faster or slower may have reduced performance.
Adjust the hardener amount based on ambient temperature and humidity:
Higher temperature and humidity: Faster curing; reduce hardener amount.
Lower temperature and humidity: Slower curing; increase hardener amount.
Use a precision scale to accurately measure the hardener. If unavailable, use a measuring cylinder or syringe for precise measurement.
5. Mix the Silicone and Hardener Thoroughly
After adding the hardener, mix the silicone thoroughly.
Use a low-to-medium-speed mixer (e.g., paint mixer).
The mixing time varies depending on the silicone quantity but generally takes 1-2 minutes.
Ensure the hardener is fully incorporated into the silicone for even distribution.
6. Remove Air Bubbles
To achieve a smooth mold, eliminate any air bubbles formed during mixing.
Use a vacuum machine for 1-2 minutes for optimal results.
If unavailable, apply vibration to the mold.
Alternatively, use an air gun or blow on the surface to burst bubbles.
7. Allow Silicone to Cure Completely
After pouring, let the silicone cure undisturbed.
Once cured, carefully separate the mold from the model.
For best results, wait at least 24 hours after curing before starting production.
When working with challenging materials like polyurethane, allow the mold to rest and clean it at regular intervals between casts.
