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
