This high thermal conductivity adhesive paste is a 2-part epoxy with a long 4-hour working time. It is dark grey, smooth, viscous, thixotropic, and bonds well to a wide variety of substrates.

Use this thermal adhesive paste to glue heat sinks to LEDs, CPUs, and other heat-generating components. This product is highly viscous and must be mixed by hand prior to application. We also offer a lower viscosity alternative (8329TFS) suitable for use with mixing tips.

This adhesive has been formulated to have a long working time. We also offer fast-curing alternatives with 5-minute (8329TCF), and 45-minute (8329TCM) working times. Electrically conductive alternatives (8331S and 8330S) and thermal pastes are also available.

Features & Benefits
  • Thermal conductivity of 1.4 W/(m·K)
  • 1:1 mix ratio
  • Working time: 4 hours
  • Cure time: 1 hour at 80 °C (176 °F)
  • Provides strong electrical insulation
  • High tensile strength
  • Strong resistance to humidity, salt water, mild bases, and aliphatic hydrocarbons
  • NASA low outgassing approved

We are a well-reputed Supplier of Medium Cure Thermally Conductive Adhesive (8329TCM) in Maharashtra, India. The 8329TCM Medium Cure Thermal Conductive Adhesive is an electronically insulating epoxy that combines moderate curing rate and high-thermal conductivity. It has a convenient 1-to-1 ratio, a workable 45 minutes pot life, and a moderate curing rate. It may achieve a minimal service cure in seven hours at room temperature. The cured adhesive bonds very well to most substrates used in electronic assemblies. It resists thermal and mechanical shocks.

 Features :

  • Excellent 1.36 W/ (m¢K) thermal conductivity
  • Easy 1:1 mix ratio
  • Adheres to most electronic substrates
  • Stores and ships at slightly below room temperature  no freezing or dry ice required
  • Very long shelf life of at least two years  even when stored at room temperature
  • Strong water and chemical resistance to brine, acids, bases, and aliphatic hydrocarbons


Applications :

  • The 8329TCM is used for thermal management situations requiring superior bonding strengths and good thermal transfers. For example, it is used to as a die-attach for electrical and electronics, increasing their long-term reliability.
  • It is great for heat sink bonding. It is also used as a high-powered LED adhesive that maximizes the lifetime of LEDs by dissipating their heat.

Application Instructions :

  • Follow the procedure below for best results. For mixing quantities that are less than 1 mL in size or for stricter stoichiometry control, mix by weight ratio instead (requires a high precision balance).
  • Heat cure is recommended to get the best possible conductivity.


To prepare 1:1 (A:B) Mixture :

  • Remove cap or cover.
  • Measure one part by volume of A.
  • Measure one part by volume of B.
  • Thoroughly mix the parts together with a stir stick until homogeneous.
  • Apply with an appropriate sized stick for the application area.


Note :

  • Remember to recap the syringe or container promptly after use.
  • Tip: Note that the material viscosity decreases with mixing, so the material will be most liquid-like and easily applied immediately after being mixed. Due to short cure time, apply as soon as possible after mixing.
  • To heat cure the 8329TCF
  • Put in oven at 65oC [149oF] for 15 minutes.
  • Tip - Hair dryers are normally rated not to exceed 60oC, so they can generally be used to accelerate the cure.
  • Attention - Keep the curing temperature well below temperature limit of heat sensitive components that may be present. As a guideline, remember that commercial grade devices normally can be safely operated up to 70oC, industrial grade up to 85oC, and military grade up to 175oC.
  • Attention - Heat guns can easily exceed the temperature limits for your assembly: they should not be used.
