Hernon® Ultrabond® 750 is a UV curable adhesive that can be used to seal a variety of plastics when exposed to UV light. The sealant offers a water- tight seal with excellent environmental resistance. Prevents material escaping through a crimped seal. With Ultrabond 750 a low powered UV lamp (Blacklight), can be used to inspect for the presence of adhesive on the substrates. Product Benefits • UV fluorescence for in-process inspection •Cures well at 395nm •Flexible thermoset system • Excellent Water Resistance •Good adhesion to a variety of plastics • 100% solid system (no solvents) • Good gap filling properties • No shrinkage due to solvent evaporation • Rapid UV cure

Hernon® 525 is a pre-applied, micro-encapsulated adhesive for threaded fasteners. Hernon® 525 stays on the bolt until the shearing action of an engaging nut applied to the coated bolt causes the capsules to break allowing the adhesive to cure. This material securely locks and seals against vibration loosening and fluid leakage. Typical Applications Locking & Sealing: • Head bolts • Truck Axle bolts • Transmission nuts • Pipe plugs and fittings Product Benefits • Improves reliability. • Prevents loosening of bolts due to vibration. • Seals against leakage. • Prevents threads from corroding. • Easily visible for inspection. • Pre-coated parts can be packaged and shipped in normal fashion. • Excellent solvent resistance. •Bonds to stainless steel bolts.

Hernon® External Ammunition Sealant 76984 is a single component high strength U.V. anaerobic sealant. 76984 has a low viscosity penetrating material capable of bonding and sealing primers and case mouths in ammunition. This Sealant is specially formulated for Ammunition that needs greater fit tolerance and higher bullet pull forces. Curing occurs when the adhesive is applied between mating surfaces. The cured adhesive is a thermoset plastic and endures exposure to most solvents. Ammunition Sealant 76984 cures quickly at room temperature without the need for surface activators or heat to seal primer and case mouth assemblies. Fixturing strength develops in two to three minutes, Full strength will be reached in 24 hours. Cure fillets at UV light irradiances above 100 milliwatts/cm² to insure proper cure. Product Benefits • UV fluorescence for in-process inspection • 100% solid system (no solvents) • Excellent environmental resistance • Good gap filling properties • Excellent Bullet Pull strengths with low Standard deviation. • UV and anaerobic curing mechanism suitable for metal parts • Good capillary performance

Dissipator® 745 is a thermally conductive room temperature cure adhesive that is designed for bonding electrical components to heat sink with a controlled gap. Dissipator® 745, through a special shimming property, insulates the component electrically while allowing thermal conductivity. This special shimming feature produces a constant gap of 0.005 in. to 0.006 in. between components.

Hernon® HPS Activator 4322 is used to activate Hernon® Hernon Porosity Sealant (HPS) resins. HPS resins cures to form a thermoset polymer when exposed to elevated temperature. Thermal content and coefficient of thermal transfer in the workpieces influence the cure rate of the HPS system. Higher temperatures produce quicker cure rates. HPS resins generally cures within the range of 177°F (80°C) to 205°F (96°C). Proper cure requires the workpiece to uniformly attain full cure temperature. Parts that do not transfer heat well will required longer processing times. Efficient thermal conductivity yields shorter processing cycles. Parts with heavier cross sections require longer exposure at heat to attain sufficient temperature internally. Carefully consider part geometry.
