GF3500LV Datasheet, PDF (1/1 Pages) List of Unclassifed Manufacturers – Thermally Conductive, Low Outgassing, Liquid Gap Filling Material

Gap Filler 3500LV (Two-Part)
Thermally Conductive, Low Outgassing, Liquid Gap Filling Material
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 interfaces on applications
• 100% solids - no cure by-products
Gap Filler 3500LV 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 material will cure at room
temperature or 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,
Gap Filler 3500LV provides a soft,
form-in-place elastomer that is ideal for fragile
assemblies or for filling intricate air voids.
Typical Applications:
• Lighting
• Automotive in-cabin electronics
• Medical electronics
• Industrial controls
• Optics
