Tuffbond® 394

PRODUCT DESCRIPTION

Tuffbond® 394 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® 394 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 was commonly used for this application, but limitations such as mixing ratio, cure speed, potential solidification in equipment and the need for equipment flushing solvents have made Tuffbond® 394 more practical.

Grade: 394
