Special features of 432

• Totally non-migrating and remains where it is applied
• Won’t spill or leak
• Excellent when working overhead or in tight places

this thread locking paste is a thixotropic version of Nuts N’ Bolts 439, a one component, high strength anaerobic adhesive.  Nuts N’ Bolts 439 cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration, it is particularly fast curing thereby reducing or eliminating the need for activators, particularly suited for heavy duty applications such as bolts used in transmissions, construction equipment or railroad assemblies where heavy shock and stress levels are required. The thixotropic nature of Nuts N’ Bolts 439 reduces the migration of liquid product after application to the substrate.

Typical Applications

EF Accelerator 75 is used to provide curing on inactive surfaces, speed the cure on active surfaces and increase the curing speed between bonding surfaces.  Also good for Hernon’s Instantbond and Quantum products

Non flammable activator 75

Directions for use

Apply adhesive to one of the surfaces to be bonded and assemble parts.   Apply Accelerator 75 over all exposed adhesive by spray or by drop. (Use one drop of activator per one drop of exposed adhesive) Surface Activation.  Apply one coating of Accelerator to the area to be bonded by spray, brush or dipping. Contaminated surfaces may need special cleaning or degreasing prior to activation to remove any soluble contamination.  Allow the solvent time to evaporate until the surfaces are completely dry (approx. 30- seconds).  Apply the Cyanoacrylate product immediately after drying or not more than 45 seconds thereafter.  Activator can be re-applied if necessary if there is a delay of more than 45 seconds between original activator and adhesive application.

Oxygen system pipe sealant 950

Hernon Dripstop 950 is a pipe joint & thread sealant that is highly recommended where oxygen, aggressive chemicals, such as chlorine or powerful oxidisers, are present. It is a high density inert thread sealant and lubricant, specially formulated for severe high pressure applications. Oxygen system pipe sealant 950 is odoorless, non corrosive and hydrophobic.  It is totally non migrating and remains where it is applied.  It is ideal for use in repetitive assembly and where disassembly is required, even after long periods of time.  It can seal up to 10,000 psi on ¼” NPT threads.

Oxygen system pipe sealant 950 Product benefits

Non flammable, chemically inert, non toxic, stable to 450ºF, will not burn, will not melt, non migrating, lasts indefinitely, excellent anti-seize properties, high dielectric strength, high density, non corrosive, odorless, lasts indefinitely, has high dielectric strength, contains no silicone or hydrocarbons, low turning torque, easily sheared.

Dripstop Family

Hernon Dripstop Anaerobic Pipe Thread Sealant

Hernon’s family of Dripstop sealants are engineered to provide many distinct advantages over conventional pipe dopes for plumbing, refrigeration and hydraulic applications. Anaerobic pipe sealants and adhesives are superior to other sealing methods in that they contain no solvents and they do not shrink, stretch, split, rot, distort, wear out or relax over time and joints never loosen from vibration. Dripstop sealants harden without shrinkage in the joints and create a tough, insoluble, vibration proof seal that will not leak even if the threads are damaged.
Dripstop products do not shred like tape dope and they are not subject to cold flow, pressure or temperature phenomena like non-hardening dopes.

Typical Applications

Sealing and locking pipe threads, Hydraulic line fittings, Pneumatic line fittings, Fuel line fittings, Steam lines, Pipe plugs, Assembly and bearing lubricant, Cryogenics, Instruments, Welding, Oil Drilling /H2S, Pulp and paper processing, Waster-water processing (safe water-treatment chemicals used in chlorinators, pumps, valves)

Thermally conductive adhesive 745

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

Thermally conductive adhesive 745 Directions for use

For best performance bond surfaces should be clean and free from grease.  Use applicator to apply the activator to the surface to
be bonded.  After the solvent evaporates, the active ingredients will appear wet, and will remain active for up to 2 hours after application. Contamination of the surface before bonding should be prevented.  Apply adhesive to the unactivated surface.  Secure the assembly, and wait for the adhesive to fixture (approximately 5 minutes) before any further handling. Full cure occurs in 4 to 24 hours.  The amount of adhesive applied to the part or heat sink should be limited to the amount necessary to fill the bond and just enough to give a small fillet.  The dispensing or application of the adhesive should be done as to minimize air entrapment within the bondline.  The successful application of this product depends on accurate dispensing on the parts to be bonded.
