Adhesion Promoter 42 is a single component product designed to improve adhesion to low surface energy plastics such as polyethylene, polypropylene, and Santoprene to similar substrates using Quantum® and Instantbond® adhesives.

Nuts N’ Bolts® 431 is a wicking anaerobic used for preassembled equipment and structures where penetration into fastener connection points is required. This product allows very simple preventive maintenance by permitting thread locking without dismantling equipment. The product “wicks” into voids by capillary action. Use Nuts N’ Bolts® 431 to seal pores or pinhole porosity in welded seams, tanks, castings, or metal parts. The cured adhesive is a thermoset plastic suitable for temperatures up to 400°F (204°C), and exposure to most solvents.

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.

Threadpaste 432 is a single component anaerobic thread-locking compound designed for heavy duty applications subject to operating temperatures to 450°F (232°C). The product delivers high strength locking and sealing on screws, nuts, bolts, studs and fittings. Excellent break-loose and prevailing torque values assure maximized resistance to transverse vibration loosening at elevated temperatures.

Weld Sealant 433 is a single component anaerobic penetrating adhesive and sealant. Utilizing capillary action, Weld Sealant 433 penetrates and seals porosities and cracks as large as 0.127 mm. Once confined away from air Weld Sealant 433 cures to a thermoset plastic. Sealant remaining on the surface will not cure and can be easily wiped clear. Benefits include retention of fluids and pressures as well as corrosion and contamination elimination. Temperature resistance is up to 400°F (204°C). Weld Sealant 433 is impervious to most solvents. Welds, castings and powder metal parts can be sealed to their rupture pressure.

Nuts N' Bolts® 434 is a thixotropic, 100% active anaerobic compound which solidifies with reliable and expected strength upon application to most fasteners. Particularly suitable for applications on less active substrates such as stainless steel and plated surfaces, where disassembly with hand tools is required for servicing. Nuts N' Bolts® 434 is easily applied. No mixing (single component), no curing outside the joint and no torque adjustments are necessary. Nuts N' Bolts® 434 offers increased profitability, having approximately 80% cost advantage over the cheapest mechanical methods as well as reducing inventories, maintenance, and the need for costly precision tolerances. Nuts N' Bolts® 434 can be used on up to 3/4inch bolts with light oil contamination.

Activator 45 is solvent-free and designed to initiate the cure of Hernon® toughened acrylic adhesives. Since Activator 45 contains no solvents, no waiting time for solvent evaporation is needed prior to assembly.

Primer 46 is a single component, solvent-free, reactive monomer-based product designed to promote the cure speed of Hernon® anaerobic adhesives and sealants. Primer 46 is used where increased cure speed of Hernon® anaerobic adhesives and sealants is required. It is especially recommended for applications with passive metals or inert surfaces and with large bond gaps. It is particularly recommended for cure conditions below 15°C.

Grenade Igniter Case Sealant 47422 is a single component UV and anaerobic curing adhesive. Grenade Igniter Case Sealant 47422 is a low viscosity penetrating material that works by capillary action between mating surfaces. The cured adhesive is a high performance thermoset plastic suitable for temperatures up to 400°F (204°C). Grenade Igniter Case Sealant 47422 cures quickly at room temperature without the need for surface activators or heat to join assemblies. Fixturing strength develops in five minutes, or within 10 seconds by exposing the edge fillets to high intensity long wavelength UV light (365 nm). Full strength will be reached in 24 hours. Cure fillets at UV light irradiances above 60 milliwatts/cm² to insure proper cure.

Tuffbond® 47771 adhesive/sealant is a two-component epoxy. This adhesive is a 100% solid system, one to one ratio, room temperature cure system.

Activator 47 is solvent-free and designed to initiate the cure of Hernon toughened acrylic adhesives. Since Activator 47 contains no solvents, no waiting time for solvent evaporation is needed prior to assembly.

Blank Ammunition Sealant 48641 Is a medium viscosity, UV and LED curable compound formulated to provide high performance, fast curing, coating and sealing of ammunition blank tips. This product is also used for shallow potting applications.

Accelerator 48 is a solvent-based accelerator for instant adhesives. The accelerator is designed to speed the cure of Hernon cyanoacrylate adhesives. Accelerator 48 is used where increased cure speed of Hernon® cyanoacrylate adhesives is required. Especially recommended for applications involving printed circuit board wire tacking and tamper proofing of adjustable components.

Primer 49 is a single component, non-CFC solvent based product designed to promote the cure speed of Hernon® anaerobic adhesives and sealants. Primer 49 is used where increased cure speed of Hernon® anaerobic adhesives and sealants is required. It is especially recommended for applications with passive metals or inert surfaces and with large bond gaps. It is particularly recommended for cure conditions below 15°C. Primer 49 meets the requirements of MIL-S-22473E (Grade T) and ASTM D5363 (Grade T).

Primer 50 is a single component, non-CFC solvent-based product designed to promote the cure speed of Hernon® anaerobic adhesives and sealants. Primer 50 is used where increased cure speed of Hernon® anaerobic adhesives and sealants is required. It is especially recommended for applications with passive metals or inert surfaces and with large bond gaps. It is particularly recommended for cure conditions below 15°C.

Activator 51 is a solvent-free product that is designed to initiate the cure of Hernon® toughened acrylic adhesives. Since Activator 51 contains no solvents, no waiting time for solvent evaporation is needed prior to assembly.

Self Locker 523 is a pre-applied micro-encapsulated adhesive for threaded fasteners. Self Locker 523 stays dry-to-the-touch 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.
