gap filler 1100sf is the thermal solution for silicone-sensitive applications.the material is supplied as a two-part component, curing at room or elevated temperatures.the material exhibits low modulus properties then cures to a soft, fexible elastomer, helping reduce thermal cycling stresses during operation and virtually eliminating stress during assembly of low-stress applications. the two components are colored to assist as a mix indicator (1:1 by volume). the mixed system will cure at ambient temperature. unlike cured thermal pad materials, the liquid approach offers infnite thickness variations with little or no stress during assembly displacement. gap filler 1100sf, although exhibiting some natural tack characteristics, is not intended for use in thermal interface applications requiring a mechanical structural bond. application gap filler 1100sf can be mixed and dispensed using dual-tube cartridge packs with static mixers and manual or pneumatic gun or high volume mixing and dispensing equipment (application of heat may be used to reduce viscosity). note: to build a part number, visit our website at www.bergquistcompany.com. gap filler 1100sf (two-part) typical applications include ? hard disk assemblies ? silicone-sensitive optic components ? silicone-sensitive electronics ? dielectric for bare-leaded devices ? filling various gaps between heat-generating devices to heat sinks and housings ? mechanical switching relay configurations available ? supplied in cartridge and kit form pds_gf_1100sf_0712 features and benefits ? thermal conductivity: 1.1 w/m-k ? no silicone outgassing or extraction ? ultra-conforming, designed for fragile and low-stress applications ? ambient and accelerated cure schedules ? 100% solids C no cure by-products product description thermally conductive, silicone-free, liquid gap filling material july 2012 pr oper ty imperial va lue metric va lue test method color / pa rt a y ello w y ello w visual color / pa rt b red red visual viscosity as mixe d (cps) (1) 450,000 450,000 astm d2196 density (g/cc) 2.0 2.0 astm d792 mix ratio 1:1 1:1 ? shelf life @ 25c (months) 6 6 ? pr oper ty as cured color or ange or ange visual hardness (shore 00) (2) 60 60 astm d2240 9 . 0 ) k - g / j ( y t i c a p a c t a e h 0.9 astm e1 269 continuous use t emp (f) / (c) -76 to 257 -60 to 125 ? electric al as cured dielectr ic strength (v/mil) 400 400 astm d149 dielectr ic constant (1000 hz) 5.0 5.0 astm d150 v olume resistivity (ohm-meter)1 0 10 10 10 astm d257 4 9 . l . u o - v o - v g n i t a r e m a l f thermal as cured therm al conductivity (w/m-k ) 1.1 1.1 astm d5470 cure schedule po t life @ 25c (3) 240 min (4 hr) 240 min (4 hr )? 4 2 ) 4 ( ) s r h ( c 5 2 @ e r u c 24 ? cure @ 100c (min) (4) 10 10 ? 1) brookf ield rv ,h eli-p ath,s pindle tf @ 2 rp m, 25c . 2) thirt y second dela y value shore 00 hardness scale . 3) time for viscosity to doub le . 4) cure schedule (rheometer - time to read 90% cure) typical properties of gap filler 1 100sf tempera ture dependence of viscosity the viscosity of the gap filler 11 00sf materi al is temper a- ture dependent. the tab le belo w prov ides the mu ltiplication factor to obtain viscosity at var ious temper atures.t o obtain the viscosity at a give n temper ature, look up the mu ltiplica - tion factor at that temper ature and mu ltiply the cor re- sponding viscosity at 25c. t emperatur e multiplication factor c par t a pa rt b 20 1.43 1.57 25 1.00 1.00 35 0.58 0.50 45 0.39 0.30 50 0.32 0.24 example - viscosity of part a @ 45: viscosity of part a at 25c is 450,000 cp. the multipli- cation factor for part a at 45c is 0.39. therefore: (450,000) x (0.39) = 175,500 cps
