P<\/span><\/strong>roduct Description<\/span><\/strong><\/p>\n

Hernon \u00a0Tuffbond \u00a0395 <\/strong>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 \u00a0395 <\/strong>will change from amber-yellow to a reddish brown upon cure.<\/p>\n

Bonding the voice coil to the cone has been a challenge for \u00a0engineers, \u00a0specifically\u00a0 when \u00a0the \u00a0adhesive temperature resistance requirement is above 200\u00baF (93\u00baC). 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 \u00a0395 <\/strong>more practical.<\/p>\n

P<\/span><\/strong>roduct Benefits<\/span><\/strong>
\nHigh temperature resistance.
\nSingle component (no mixing, no pot life). Solventless.
\nCures on demand (heat cure).
\nWill not slip during cure.
\nFast setting: 1.5 minutes at 150oC bondline. Changes color upon cure (yellow to brown). Excellent adhesion to various substrates. Gives high shear.
\nLow water absorption. Very rigid.
\nLow density.
\nNo porosity upon cure.<\/p>\n
