Epoxy AdhesivesLoctite ® Product, Ordering and Technical InformationLoctite ® epoxies are recommended for the most demanding and highly stressed voice coil bonding applications.Three DURABOND epoxies excel in this area, as they are particularly suited for production environments where speedof cure is not as critical as performance. These are two-part, room-temperature curing adhesives, that are toughenedto provide high peel and shear strength on a wide variety of plastics and metals.DURABOND two-part epoxies offer superior adhesion to metals, and high thermal and chemical resistance,as well as extra high cohesive strength with low shrinkage. The DURABOND products are packaged inside-by-side cartridges, which are easily dispensed through hand held meter-mix dispensing systems. Available in50 ml, 200 ml and 400 ml dual cartridges, as well as 5 gallon bulk sizes for high volume and automated assemblyoperations. For dispensing equipment and accessories, see page 31.Speaker Application:Bonding Voice Coil to Spider to ConeProduct Features & Benefits:• 100% resin solvent-free adhesives.• Superior adhesion to metals, including dichromated and plated metals.• Room temperature cures; friendly two-part, easy to dispense formulations.• Low shrinkage and CTE.• High cohesive strength.• High thermal and chemical resistance.Loctite has a wide range of DURABOND epoxies and urethanes to select from.
