Tuffbond® 395


Tuffbond® 395 is a single component, high temperature resistant, heat-activated epoxy. It cures to a high-performance thermoset system with excellent adhesion properties to a wide variety of substrates. Tuffbond® 395 will change from amber-yellow to a reddish-brown upon cure. Bonding the voice coil to the cone has been a challenge for engineers, specifically when the adhesive temperature resistance requirement is above 200ºF (93ºC). Two-component epoxy has been most commonly used for this application, but limitations such as mixing ratio, cure speed, potential solidification in equipment and static mixers and the need for equipment flushing solvents have made Tuffbond® 395 more practical.

Grade: 395
