Product Description
Hernon 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. The rapid curing mechanism of 1.5 minutes at a bondline temperature of 150ºC makes it ideal for production line use. 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 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 394 more practical. 全文 »
