High temperature Thermal Cement

from $5.00

Our high temperature thermal cement is designed to provide excellent thermal conductivity, combined with the ability to retain it’s shape after heating. Unlike traditional thermal pastes and glues, this thermal cement can survive 800C+ temperatures without degrading. Once cured, the cement forms a hard ceramic composite that has a similar thermal conductivity to many metals (75+ W/mK)!

This cement is perfect for attaching and filling gaps around ceramic heaters, gluing down thermistors, and even casting entire ceramic components or liners around parts. It can also be painted on to form a thin ceramic layer on various different materials!

Our thermal cement does not produce any volatile off-gassing after curing, however it should still be treated with caution during handling. Gloves are required for safe handling of the uncured cement, and masks/respirators are advised around any dust that is produced from broken cured cement. Cement is NOT food safe, and careful cleaning must be done to prevent exposure or ingestion.

Instructions for use

As Glue

  • Apply PPE and mask areas of part where cement should not make contact.

  • Apply cement to desired areas in small amounts via syringe, or place onto a disposable mixing surface and brush on with customer provided tools (cement can be rinsed off of tools quickly before it hardens to clean them).

  • Allow cement to dry for at least 12 hours before heating (time will vary based on CO2 exposure and temperature of cement, enclosed areas will take longer to cure).

  • Heat cement up to between 50 and 80C and maintain that temperature for 1 hour

  • Gradually heat cement up to the expected operating temperature to finish curing and verify results.

    As Casting Cement

  • Apply PPE, clear workspace

  • Prepare mold (preferably silicone) with release agents and cleaning.

  • Slowly Inject cement into the mold and shake/tap to prevent bubbles from being trapped

  • If possible, seal mold in a container with a source of CO2. Placing a small amount of vinegar in a cup, then adding a little baking soda before sealing the container works well as an at home option.

  • Wait at least 24 hours. If cement is not fully cured, more CO2/air exposure time is needed.

    Warnings

May cause irritation to skin and eyes. If cement is exposed to skin, wash thoroughly with warm water and soap as soon as possible. If cement is exposed to eyes, rinse eyes with cool water thoroughly for several minutes and seek medical advice. If cement is ingested, do not induce vomiting and contact Poison Control immediately.

Cement is not compatible with alcohols of any kind when un-cured. Contact with alcohols will cause spontaneous curing and clumping that is irreversible.
