3873 is a self-shimming, thermally conductive adhesive.
When used with Activator 7387™, it cures rapidly to form a high strength, high modulus, thermoset acrylic polymer.A uniform bondline thickness of 0.127mm results from theincorporation of solid glass spheres.
Recommendedapplications include the bonding of various heat generatingdevices (power devices) to thermal spreaders.TYPICAL PROPERTIES OF UNCURED MATERIAL

3873是一種自動補(bǔ)片導(dǎo)熱粘合劑。
當(dāng)與激活劑7387™一起使用時(shí)，它可快速固化形成高強(qiáng)度，高模量，熱固性丙烯酸聚合物。均勻的粘合線厚度為0.127mm，來自固體玻璃球的產(chǎn)生。
推薦應(yīng)用包括將各種發(fā)熱裝置（動力裝置）與散熱器結(jié)合。
