美国赫能HERNON Tuffbond 395 TDS

Product Description

Hernon  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.

Product Benefits
