No-Mix Acrylic Structural Adhesives


Bottle	Cartidge	Syringe	Tube	Single-Use Capsule

No need to mix these acrylics—apply adhesive to one surface and activator to the other, then join. Acrylics bond with the widest range of materials of any adhesive. They adhere to plastic especially well, requiring little surface preparation.

Cartridge—Apply these adhesives with a caulk gun.

Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.

Epoxy Structural Adhesives for Harsh Environments

Cartridge

With excellent resistance to corrosive chemicals, these epoxies maintain bonds in tough conditions.

Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal. Choose an adhesive that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.

These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.

Model Number E-120HP—Resist acetone, fuel, and oil. These adhesives also bond dissimilar materials and withstand rapid changes in temperature.

Cartridge—To mix and dispense these adhesives, you'll need a mixer nozzle and dispensing gun.

Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.

Slow-Set Epoxy Structural Adhesives

Cartridge

Take your time positioning parts—these epoxies remain adjustable for at least 90 minutes before setting. Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal.

These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.

Cartridge—To mix and dispense these adhesives, you'll need a mixer nozzle and dispensing gun.

Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.

Light-Activated Instant-Bond Adhesives

Take your time positioning parts that require precise alignment, such as optical instruments. Instead of gripping immediately, these adhesives only harden when you expose them to a compatible light source.

Thick Liquid—Fill larger gaps than thin-liquid adhesives, so they're better for bonding slightly misaligned or uneven surfaces.

Adhesive Primers for Acrylic Plastic Adhesives, Retaining Compounds, and Threadlockers


Aerosol Can	Can	Applicator-Top Bottle, Spray Bottle

To speed cure time on coated fasteners, aluminum, stainless steel, or titanium, apply these adhesive primers before using threadlocker or retaining compound. They also work with no-mix acrylic adhesives.

Applicator-Top Bottle—Adhesive primers in applicator-top bottles also include a spray head for easy dispensing.

Light-Activated Epoxy Potting Compounds

Handle potted items within minutes—these potting compounds dry quickly when exposed to UV light. For added strength and durability, cure them with heat. Since they’re epoxy, they won’t break down from chemicals or moisture. They’re also excellent electrical insulators and withstand a wide range of temperatures. Use them to shield components from dust, moisture, chemicals, mechanical shock, and vibration. You need a mixer nozzle (not included) and a gun and plunger (both sold separately) to dispense. The nozzle lets you apply these compounds precisely.

For maximum effectiveness, these compounds need to be heat cured after they’re cured with UV light. Overall dry time includes heat curing at 149° F.

Urethane Potting Compounds

Encase electronic assemblies in a layer of urethane for protection from dust, moisture, chemicals, mechanical shock, and vibration. Urethanes withstand a wide range of temperatures and are the best choice for cold-temperature applications. They have excellent flexibility, good chemical and moisture resistance, and provide good electrical insulation.

Cartridge

Cartridge potting compounds can be applied precisely through the included mixer nozzle. You’ll need a dispensing gun (sold separately).
