Epoxies

High-Performance Epoxy Adhesives from a Leading Epoxy Adhesive Manufacturer

As a trusted epoxy adhesive manufacturer, Hernon Manufacturing offers a wide range of epoxies in both single and two-component formulations to meet your exact bonding needs. Two-component epoxies are chemically curing materials with two separate components—one serving as an adhesive and the other as a chemical initiator. These epoxies rarely require batch mixing and are typically dispensed using static mixing wands from preformed duo-part packages, ensuring a perfect dispensing ratio each time.

Single-component epoxies, on the other hand, are heat-cure adhesives that require a certain temperature to initiate the crosslinking (curing) reaction. Whether you need fast room temperature cure epoxies or low-chlorine formulations, Hernon Manufacturing provides tailored solutions to meet diverse industry needs.

With a library of over 5,000 unique adhesives and sealants, including custom-made formulations, Hernon offers comprehensive support in bonding even the rarest combinations of substrates in any environment.

Tuffbond® 310

Tuffbond® 310 adhesive/sealant is a two-component epoxy, 100% solid system, two to one ratio, room temperature cure system. Tuffbond® 310 is recommended for bonding metals, wood, and ceramics.

Tuffbond® 394

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 200°F (93°C). 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.

Tuffbond® 313

Tuffbond® 313 adhesive/sealant is a two component, 100% solid system, one to one ratio, room temperature cure system. Tuffbond® 313 is recommended for bonding metals, wood, ceramics, etc., and can be used for potting and encapsulation of electrical and electronic components.

Tuffbond® 302

Tuffbond® 302 is a modified epoxy adhesive that provides a very fast room temperature cure. Tuffbond® 302 exhibits very good moisture chemical and heat resistance. This very fast cure epoxy adhesive is specially formulated for rapid in-line assembly of loud speakers. Tuffbond® 302 is also recommended for bonding metals, wood, ceramics, etc., and can be used for potting and encapsulation of electrical and electronic components.

Tuffbond® 317

Tuffbond® 317 is a two component, room temperature cure system. By changing the ratio of resin and hardener, the cured adhesive can change from a tough and flexible to a hard and rigid system.
