SILCOOL™ TIA221GF LIQUID-DISPENSED SILICONE THERMAL PAD / GAP FILLER

  • Product code: TIA221GF
  • Manufacturer: Momentive
  • Package size: 20L Drum
  • Shelf Life: Contact with us for detail

SILCOOL™ TIA221GF is a two-component, thermally conductive silicone material that is dispensed as a liquid and cured in place to create a heat path for efficient heat transfer. After being applied, its non-slumping pasty consistency offers physical stability to prevent run-off after dispensing. SILCOOL™ TIA221GF can typically be used as a liquid dispensed alternative to pre-fabricated thermal pads, and as a gap filler for a broad array of thermal designs in electronic components.

KEY FEATURES of SILCOOL™ TIA221GF 

  • Low density
  • Good thermal conductivity
  • Easy to use 1:1 mixing ratio
  • Fast, room temperature cure and good thixotropic properties
  • Flame retardant: UL94 V-0 equivalent
