Vacuum Grease and Vacuum Epoxy

Overview

Vacuum Epoxy
Thorlabs' Vacuum Epoxy can be used to seal leaks in vacuum equipment down to 10^-9 Torr. This line of epoxy can form a high-strength, long-term bond with metals, ceramics, or glass and does not require solvent to evaporate. 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.

High-Temperature and Low CTE Epoxy
This two part, 100% solid, heat curing epoxy can be used in applications requiring constant performance at temperatures up to 250 °C. It can handle 250 °C to 350 °C for brief periods. The epoxy is vacuum compatible and passes NASA low outgassing standard ASTM E595.

Silicone Vacuum Grease
Silicone grease, a general laboratory lubricant, works over a higher temperature range (-40 °C to 260 °C) than hydrocarbon greases. Silicone grease can be used for both vacuum and non-vacuum applications, such as lubricating rubber gaskets, glass-to-rubber boundaries, and water-treating equipment.

Apiezon Grease
For higher vacuum requirements, Thorlabs offers apiezon grease, which contains PTFE for higher lubricity and has an optimal working range of 10 °C to 30 °C. Apiezon grease is recommended for both general applications and vacuum applications down to 10^-9 Torr. This grease comes in a syringe for easy use and is ideal for re-lubricating the leadscrew threads of our Z8, ZFS, and ZST actuators.

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.

Bonjour, Je voulais savoir si votre colle TS10 ne dégaze pas sous vide ainsi pollué l’intérieur du milieu sous vide. Merci par avance. Bien cordialement.

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.

This silicone grease is very popular as a general laboratory lubricant and is commonly used as a stopcock grease, to lubricate synthetic or silicone rubber gaskets, or at glass-to-rubber boundaries. However, it should not be used on fluorosilicone O-rings and gaskets. In addition, the lubricant can also be used for a wide array of non-vacuum applications such as the lubrication of water-treating equipment, general laboratory equipment, or O-rings for binoculars and telescopes.
