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.

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. 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.

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® 429 is a single component anaerobic thread locking adhesive. Nuts N’ Bolts® 429 is a high-strength adhesive for locking and sealing large bolts and studs 1inch and larger diameters. Curing occurs only when adhesive is confined between mating surfaces. The cured adhesive is suitable for temperatures up to 300°F (149°C) and exposure to most solvents.

Nuts N’ Bolts® 428 is a single component anaerobic threadlocking 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. Meets requirements of CID A-A-59720 Grade HT

Nuts N’ Bolts® 427 is a single component anaerobic thread locking material, which develops high strength. The product cures when confined in the absence of air between close fitting metal surfaces.

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.

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.

Porosity Sealant (HPS) 41814 is the solution to leak proof parts, improving machinability, in addition to increasing the durability and surface quality for painting and plating. The hardened resins exhibit superior chemical resistance and elevated temperature stability. The microscopic voids, where potential leaks occur (between metal grains or ceramic plastic molecules) in the part are filled by the low viscosity resin during vacuum application. Sealed micropores cure without shrinkage when exposed to elevated temperature to form tough cross-linked thermoset polymer, permanently sealing the workpiece. Residual adhesive film is water-washed from the part surfaces during rinsing. The parts leave the impregnating process without surface residue and can then be used in production immediately. When used in preparation for plating or painting processes, the impregnation process also eliminates absorption of plating materials (like acids) or painting prep solvents that could otherwise later bleed out of pores causing finishes to discolor, bleed, pit or peel. Sealed powdered metal parts exhibit better machinability, enhanced tool life and better dimensional control.
