What Are Thermally Conductive Adhesives?

Thermally conductive adhesives are thermally conductive products designed to offer effective thermal management in heat-generating components, combined with effective bonding power to join components.

Formulated in multiple mediums, thermally conductive silicone adhesives, polyurethane resins, and thermally conductive epoxy adhesives are designed to deliver on two fronts: 

  • Facilitating thermal management objectives
  • Eliminating space-restrictive mechanical fasteners 

Creating a strong bond between components and heat sinks to reduce the need for screws and clips, Henkel thermally conductive adhesives in pad, liquid, and laminate mediums also allow reliable, long-lasting connection and effective heat dissipation in devices. 

With the ability to automate application via dispensing or custom placement solutions, Henkel thermal adhesives offer the ultimate in cost-efficiency and performance.


Why Use Henkel Thermally Conductive Adhesives?

Henkel thermally conductive glue products combine fantastic bonding abilities with unrivaled thermal management capabilities. This allows for necessary heat dissipation in heat-generating components, while also reducing the need for clips and screws. This makes conductive adhesives the perfect option when assembling smaller, lighter electronics. 

Our range of thermal adhesive products comes in a wide range of options to suit specific industry and application needs. Whether tapes, liquids or films, every product has its own specification across a range of features, including color, thickness, and thermal conductivity.

Choosing a Thermally Conductive Adhesive

LOCTITE® Bergquist® thermally conductive adhesive glues come in several different formats. Each has its own features and specifications and is well suited to certain applications. Discover the difference between different thermal adhesive product types to find your ideal solution.

Thermally Conductive Tape Adhesives

The BOND PLY family of adhesives is both thermally conductive and electrically isolating. BOND PLY materials, available in PSA or laminating formats, provide for the decoupling of bonded materials with mismatched coefficients of thermal expansion. BOND PLY offers:

  • A replacement to heat cure adhesives
  • A screw mounting and clip mounting alternative

Thermally Conductive Film Adhesives

When there is a requirement for bonding large areas or joining complex parts, thermal adhesive films are the preferred materials. Larger bonding areas are problematic for liquid-based mediums as voids may result.

Films, however, deliver uniform, void-free bondlines, and controlled thicknesses. Supplied in custom, pre-cut formats, Henkel’s line of thermal adhesive films offers a clean, waste-free, easily-processed solution with a low total cost of ownership in thermally and electrically conductive formulas.


Thermally Conductive Liquid Adhesives

Henkel’s liquid adhesives – sometimes referred to as thermally conductive glue – provide robust mechanical attachment, allowing for the elimination of fasteners such as screws and clips. This also helps reduce device size and weight to align with electronics miniaturization protocols.

These form-in-place elastomers are ideal for coupling PCB-mounted heat-producing electronic components with an adjacent metal case or heat sink. With the ability to maintain thin bondlines and excellent thermal paths, LOCTITE® Bergquist® brand liquid adhesives enable excellent thermal management performance and the ability to simplify and uniform application through the use of automatic dispensing systems.


Benefits of Thermally Conductive Adhesives

LOCTITE® Bergquist® thermally conductive adhesives offer a range of benefits. By combining heat dissipation with adhesive bonding, you can save space in components and make fasteners redundant. Benefits include: 

  • Industry-leading heat dissipation to improve component longevity and thermal performance. 
  • Strong bonds and gapless performance to enhance uniformity across seals and negate the need for mechanical fasteners.
  • Available in a variety of materials.
  • Easily conformable to reduce gaps and voids in components with a thinner bondline.
  • Easily automated and reworkable to integrate thermally conductive adhesives easily into your production.
