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.
