Features and Benefits
• Thermal conductivity: 2.0 W/m-K
• Ultra-conforming, designed for fragile and
low-stress applications
• Ambient and accelerated cure schedules
• 100% solids – no cure by-products
• Excellent low and high temperature
mechanical and chemical stability
Gap Filler 2000 is a high performance, thermally
conductive, liquid gap filling material supplied
as a two-component, room or elevated
temperature curing system.The material
provides a balance of cured material properties
and good compression set (memory).The
result is a soft, form-in-place elastomer ideal
for coupling “hot” electronic components
mounted on PC boards with an adjacent
metal case or heat sink. Before cure, it flows
under pressure like grease. After cure, it won't
pump from the interface as a result of thermal
cycling and is dry to the touch.
Unlike cured Gap Filling materials, the liquid
approach offers infinite thickness with little or no
stress during displacement and assembly. It also
eliminates the need for specific pad thickness
and die-cut shapes for individual applications.
Gap Filler 2000 is intended for use in thermal
interface applications when a strong structural
bond is not required. As cured, Gap Filler 2000
is formulated to have pliable low-modulus,
properties. Note: Resultant thickness is defined as
the final gap thickness of the application.
Typical Applications Include:
• Automotive electronics • Telecommunications
• Computer and peripherals • Thermally conductive vibration dampening
• Between any heat-generating semiconductor and a heat sink
Configurations Available:
• Supplied in cartridge or kit form
