Formulations

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.

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.

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.

Nuts N’ Bolts® 431 is a wicking anaerobic used for preassembled equipment and structures where penetration into fastener connection points is required.

Nuts N’ Bolts® 425 is a single component anaerobic thread locking material, which is thixotropic and develops medium to high strength. The product cures when confined in the absence of air between close-fitting metal surfaces.

Nuts N’ Bolts® 423 is a single component anaerobic thread locking material, which is thixotropic and develops medium strength. The product cures when confined in the absence of air between close fitting metal surfaces and is particularly suitable for less active substrates such a stainless steel and plated surfaces.

Tuffbond® 42121 is a thixotropic and modified epoxy adhesive that provides a very fast room temperature cure. Tuffbond® 42121 exhibits very good moisture chemical and heat resistance. This very fast cure epoxy adhesive is specially formulated for rapid in-line assembly of loud-speakers. Tuffbond® 42121 is also recommended for bonding metals, wood, ceramics, etc., and can be used for potting and encapsulation of electrical and electronic components.

Nuts N’ Bolts® 420 is a single component anaerobic thread locking material, which is thixotropic and develops low strength for easy disassembly. The product cures when confined in the absence of air between close fitting metal surfaces.

UV FOG (Form on Gasket) 41764A is an EB/UV curable product that provides excellent adhesion to shaft seals, oil seals, metals, glass, ceramics and plastics. Can be used as a Form-in-place gasket in oil and coolant systems. Typical applications include Engine covers, Oil pans and other fluid seal systems.

Nuts N’ Bolts® 410 is a single component, low viscosity anaerobic adhesive/sealant designed especially for wicking applications. It has the ability to penetrate porous structures and cracks by capillary action, filling voids as large as 0.005 in.

Rust Inhibitor 40 is an effective corrosion remover and rust preventative which leaves a protective finish for up to 1 year. Produces a clean, dry surface that can be painted, plated or powder coated afterward with no pre-cleaning. Not for use with zinc plated or magnesium items. Rust Inhibitor 40 is used on rusted steel when only a minimum surface preparation is practical. Rust Inhibitor 40 protects, cleans and leaves a protective coating.

Grenade Igniter Case Sealant 40995 is a single component anaerobic thread locking and sealing adhesive. Grenade Igniter Case Sealant 40995 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 40995 cures quickly at room temperature without the need for surface activators or heat to join threaded 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.

HASA 39781 is a single-component, anaerobic, structural adhesive designed for bonding rigid assemblies. HASA 39781 cure is accomplished when mating surfaces including metal, glass and ceramics are joined together. Accelerated cures are possible with the application of primers or by a short, low temperature heat cycle. Upon cure, HASA 39781 is a highly crosslinked thermoset plastic with excellent properties over a wide range of conditions.

Tuffbond® 395 is a single component, high temperature resistant, heat activated epoxy. It cures to a high-performance thermoset system with excellent adhesion properties to a wide variety of substrates. Tuffbond® 395 will change from amber to a reddish brown upon cure. Bonding the voice coil to the cone has been a challenge for engineers, specifically when the adhesive temperature resistance requirement is above 200°F (93°C). Two component epoxy systems have been most commonly used for this application, but limitations such as mixing ratio, cure speed, potential solidification in equipment and static mixers and the need for equipment flushing solvents have made Tuffbond® 395 more practical.

Tuffbond® 394 is a single component, high temperature resistant, heat activated epoxy. It cures to a high-performance thermoset system with excellent adhesion properties to a wide variety of substrates. Tuffbond® 394 will change from amber-yellow to a reddish brown upon cure. Bonding the voice coil to the cone has been a challenge for engineers, specifically when the adhesive temperature resistance requirement is above 200°F (93°C). Two component epoxy was commonly used for this application, but limitations such as mixing ratio, cure speed, potential solidification in equipment and the need for equipment flushing solvents have made Tuffbond® 394 more practical.
