The Importance of RTV Drying Before Adding Oil

Adding oil too soon after applying RTV can cause leaks and other issues. It’s essential to allow the RTV to cure completely before adding oil to prevent these problems. Additionally, moisture can interfere with RTV curing, which can affect its ability to create a proper seal. Proper drying time is crucial to achieving an effective RTV seal.

Factors That Affect RTV Drying Time

Several factors can affect RTV drying time, including:

Temperature and humidity levels: Higher temperatures and lower humidity levels can speed up RTV drying time, while lower temperatures and higher humidity levels can slow it down.

Type of RTV used: Different types of RTV have different curing times. Fast-drying RTVs take less time to cure than standard RTVs.

Thickness of the RTV layer: The thicker the RTV layer, the longer it takes to dry.

Best Practices for RTV Drying and Oil Application

Here are some best practices for RTV drying and oil application:

How long to let rtv dry before adding oil: Always follow the manufacturer’s recommended drying time for the specific RTV product you’re using. For example, SANVO’s fast-curing RTV products typically require about 30 minutes to dry.

Tips for ensuring proper RTV curing: To ensure proper RTV curing, make sure the surface is clean, dry, and free of any contaminants before applying the RTV. Additionally, avoid touching the RTV until it’s fully cured.

Guidelines for adding oil after RTV has cured: Once the RTV has dried completely, you can add oil to the system. It’s essential to follow the manufacturer’s guidelines for oil application to ensure compatibility with the RTV. For example, SANVO’s RTV products are compatible with most oils but not recommended for use with gasoline or other fuels.
