Frequently Asked Questions
What is the mix ratio for RTV11-1P?
RTV11 uses DBT (dibutyl tin dilaurate) as the standard curing agent. The mix ratio is specified in the Momentive/MG Chemicals Technical Data Sheet. Working time and cure rate can be adjusted by varying the amount of catalyst — refer to the TDS for guidance on catalyst loading for your specific application.
Can RTV11 cure in deep sections?
Standard DBT catalyst may have limitations for very deep section curing. Alternative catalysts are available to facilitate deep section curing, faster cures, and automated mixing. Contact MTE Solutions to discuss catalyst options for your specific potting or encapsulating application.
Is RTV11-1P FDA compliant?
Yes — RTV11 is FDA compliant and can be used in food contact applications, with the exception of applications involving acidic foods where specific FDA regulations apply. Confirm your specific application requirements with MTE Solutions or Momentive before use.
What is the service temperature range for RTV11?
RTV11 retains its elastomeric properties continuously from -54°C (-65°F) to 204°C (400°F), and can withstand temperatures up to 260°C (500°F) for short periods. This makes it suitable for electronics potting applications that experience elevated operating temperatures.
