GF1500LV Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – Ultra-conforming, with excellent wet-out

Gap Filler 1500LV (Two-Part)
January 2015
PRODUCT DESCRIPTION
Thermally Conductive, Liquid
Gap Filler Material
FEATURES AND BENEFITS
• Thermal Conductivity: 1.8 W/m-K
• Low volatility for silicone
sensitive applications
• Ultra-conforming, with excellent wet-out
• 100% solids — no cure by-products
• Excellent low and high temperature
chemical and mechanical stability
Gap Filler 1500LV is a two-part, high
performance, thermally conductive, liquid
gap filling material. This material offers
the high temperature resistance and low
modulus of a silicone material with
significantly lower levels of silicone
outgassing for use in silicone
sensitive applications.
The mixed material will cure at room
temperature and can be accelerated
with the addition of heat. As cured,
Gap Filler 1500LV provides a soft,
thermally conductive, form-inplace
elastomer that is ideal for fragile
assemblies or for filling unique and
intricate air voids and gaps.
Liquid dispensed thermal materials offer
infinite thickness variations and impart little
to no stress on sensitive components during
assembly. Gap Filler 1500LV exhibits low
level natural tack characteristics and is
intended for use in applications where a
strong structural bond is not required.
