TIM-LGF series

Silicone, Cure Type Dispensable Liquid Gap Fillers

Product Description:

TIM-LGF are thermally conductive liquid gap filler materials formulated to provide a balance of cured material properties, highlighted by “gel-like” modules and good compression set or memory. This material is available in thermally conductive & electrically insulating, one part or two part, room or elevated temperature curing system. Form-in-place gap fillers are ideal for applying any thickness with little or no stress.

Typical Applications:

Ideal for circuit boards where multiple packages of variable heights require a thermal path to heat sink or enclose. Automotive Electronics Control Units (ECU’s), power supplies & semiconductors, memory and power modules and fiber optics telecommunications equipment.

Special Futures:
  • Dispensable, easy mix ratio
  • Highly conformable at low pressures
  • Ambient or accelerated cure schedules
  • Thixotropic nature makes easy to dispense
  • Prevents pump-out from the interface
  • Reworkable
