FEATURES AND BENEFITS
● Thermal Conductivity: 3.5 W/m-K
● Low volatility for outgassing sensitive applications
● Ultra-conforming, with excellent wet-out for low stress
interface applications
● 100% solids - no cure by-products
BERGQUIST GAP FILLER TGF 3500LVO is a two-part, high
thermal conductivity, liquid gap filling material. This material
offers the mechanical property benefits of a silicone material
with the additional feature of low outgassing.
The mixed system will cure at room temperature and can be
accelerated with the addition of heat.
The liquid approach offers infinite thickness variations with little
to no stress to sensitive components during assembly. As
cured, BERGQUIST GAP FILLER TGF 3500LVO provides a
soft, form-in place elastomer that is ideal for fragile
assemblies or for filling intricate air voids.
