I am looking to bond silicon rubber and titanium and use this in a high temperature (~300C), high vacuum (~1E-7 torr) environment. Would this product be recommended for this application? Thanks for your help.

Hello, thank you for contacting Thorlabs. 353NDPK can handle 300 °C to 400 °C for brief periods. Furthermore, we do use this epoxy in some of our Polaris series mounts which can be used down to 10^-9 torr. I will reach out to you about the duration that you need to meet that higher temperature range.

Hello, I would like to know if this material has any water content. I am interested in using it to seal materials that are extremely reactive to H2O. Also does this material outgas O2? Thanks, Chris.

Dear Sir/Madam, I have a question. My glued fused silica component have to withstand high-vacuum (10^-7 to 10^-8 oC) working continuously at temperatures between 150 0C and 200 oC. Is it Thorseal adhesive (TS10) OK or I have to use 353NDPK? Best regards Dimitar Slavov Institute of Electronics, Bulgarian Academy of Sciences

Response from Bweh at Thorlabs USA: I would recommend the 353NDPK. When using this in high vacuum environments, I would advise you use the recommended cure schedule of 150 deg for one hour for best results.

WE are looking for a Vacuum epoxy which can be used short period of times up to 280 °C / 560 °F (reflow of SMD parts). Can TS10 take this heat? Matti Vuotila R&D Manager, Mirion Technologie (RADOS) Oy, Finland

Response from Jeremy at Thorlabs: The flash point of the TS10 is quite a bit lower than your requirement and therefore not appropriate for your application.

Vacuum Epoxy

  • Seals Leaks in Vacuum Equipment Down to 10-9 Torr
  • Forms a Reliable, High Strength, Long-Term Bond with Metals, Ceramics, or Glass
  • No Solvent Necessary to Evaporate
  • At Room Temperature: Hardens in 3 to 4 Hours, Cures in 72 Hours
  • Cures in 2 Hours at 60 °C, in 1 Hour at 82 °C, or in 20 to 30 Minutes at 121 °C
  • Mixing Ratio (by Volume): 2.5 Parts Resin to 1 Part Hardener
  • 82 g (2.9 oz) Base Resin, 36 g (1.3 oz) Hardener

Please note that epoxy resins are prone to solidification or crystallization. If this occurs, the product can easily be returned to a liquid state by immersing the tube in warm [approximately 100 °F (38 °C)] water for 30 minutes. Ensure all material is melted prior to use. Allow the resin component to return to room temperature prior to mixing with the hardener.

This epoxy resin is classified as a dangerous good in some countries. Depending on the delivery location, this item may need to be shipped separately from the rest of your order at an additional charge. Please contact our sales department if there are questions or concerns when placing an order for this item.

Please note that we are currently experiencing some supply chain disruptions that are impacting the availability of the TS10, leading to atypically long lead times (6 weeks).
We are working diligently to once again have this product stocked for same-day shipment.
