Formulations

Dripstop® 947 is a high-performance adhesive/sealant specifically formulated for the sealing and mild locking of hydraulic and pneumatic threaded parts used with hydraulic and pneumatic equipment. Dripstop® 947 will seal pipe threads, standard nuts and bolts, fittings for hydraulic and pneumatic systems, air conditioners, fittings for refrigeration equipment, and all types of water and chemical processing valves and equipment, including steam up to 350°F. Dripstop® 947 is a single component, thixotropic (non-migrating) anaerobic adhesive/sealant, that does not contain PTFE, and will provide a rapid cure at room temperature. Upon cure, Dripstop® 947 becomes a highly crosslinked thermoset plastic preventing leakage from shock, vibration as well as corrosive liquids and atmospheres.

Cylinlock® 846 is a fast-curing, high-strength anaerobic adhesive yielding higher shear strengths with temperature resistance up to 300°F (149°C). It provides relatively quick cures, outstanding solvent resistance, and improved reliability for metal service applications. Certified to NSF/ANSI Standard 61 for use in commercial and residential potable water systems.

Hernon Dissipator 746D is a thermally conductive adhesive formulated for bonding electrical components to heat sinks or printed circuit boards. Fast room temperature cure combined with excellent heat dissipation for thermally sensitive components and controlled strength for service repair provide perfect replacement for tapes, epoxies, silicones, fasteners and mechanical clips. Typical Applications Typical applications include bonding transformers, transistors and other heat generating electronic components to printed circuit board assemblies or heat sinks.

Hernon Dissipator 745D is a thermally conductive room temperature cure adhesive that is designed for bonding electrical components to heat sink with a controlled gap. Dissipator 745D, 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. Product Benefits • No mixing required (eliminates errors in mixing ratio) • Room temperature cure. No heat required. • Eliminates screws and rivets for assembly. • Eliminates the air space between components. • High k factor for heat conductive application

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. Consult Hernon® Technical Service for specific process requirements.

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.
