Permabond MT3836 – Flexible, Fire Retardant and Thermally Conductive Adhesive
Permabond is delighted to announce the introduction of Permabond MT3836 – flexible, fire retardant and thermally conductive adhesive. This two-component hybrid system cures fully at room temperature to form a flexible, thermally conductive material capable of bonding a wide variety of different substrate materials.
This product contains a thermally conductive adhesive filler which helps conduct heat away from components and is suitable for use with electronics (e.g. bonding heat sinks). It is also a popular choice for bonding electric vehicle battery modules – not only does it help with thermal management but it is also fire retardant to UL94 V-0. It is flexible and compressible so helps minimise stress on sensitive components, especially if there are differential thermal expansion and contraction forces impacting joints. The cured material helps absorb impact and vibration forces and is non-conductive for electricity.
This product can also be considered for bonding building cladding materials, providing a fire-retardant layer between cladding panels and profile sections. Its peel, impact and vibration resistance help the panel flex and maintain position in high winds. The cured adhesive is intumescent. When exposed to fire, it swells to help seal and protect the material underneath.

- Elongation >100%, Shore A hardness 60.
Which surfaces does it bond well?
This material bonds a wide variety of substrates including steel and aluminium. Its flexibility makes it more suitable than rigid epoxies for bonding Zintec surfaces (with the spangly-effect surface, often seen for air conditioning ducting etc). It is also better at bonding difficult surfaces compared to standard epoxy adhesives as its flexibility and impact resistance make the adhesive much less likely to fracture off. Permabond MT3836 is suitable for use on a wide variety of composite materials such as GRP, FRP, Carbon fibre, laminate, phenolic materials, plastics and plastic blends.
