FEATURES AND BENEFITS

● Thermal Conductivity: 3.6 W/m-K

● Thixotropic nature makes it easy to dispense

● Two-part formulation for easy storage

● Ultra-conforming, designed for fragile and low-stress

applications

● Ambient and accelerated cure schedules

BERGQUIST GAP FILLER TGF 3600 is a two-component

liquid gap filling material, cured at either room or elevated

temperature, featuring ultra-high thermal performance and

superior softness. Prior to curing, the material maintains good

thixotropic characteristics as well as low viscosity.

The result is a gel-like liquid material designed to fill air gaps

and voids yet flow when acted upon by an external force (e.g.

dispensing or assembly process). The material is an excellent

solution for interfacing fragile components with high topography

and/or stack-up tolerances to a universal heat sink or housing.

Once cured, it remains a low modulus elastomer designed to

assist in relieving CTE stresses during thermal cycling yet

maintain enough modulus to prevent pump-out from the

interface. BERGQUIST GAP FILLER TGF 3600 will lightly

adhere to surfaces, thus improving surface area contact.

BERGQUIST GAP FILLER TGF 3600 is not designed to be a

structural adhesive.
