SelfSealer® 604 is a tough, pre-applied, non-hardening threaded sealant. When dried, it becomes a resilient, tight clinging, non-curing sealant for tapered or straight threads. It provides an instant seal on different pipe threads and can be used up to eight (8) times without recoating. SelfSealer® 604 is water based, non-toxic, safe and can be applied easily without special handling precautions. It provides resistance to vibrational loosening because of its prevailing torque characteristics. Therefore, it is very effective on non-locking applications.

Dripstop® 923 is a single component, paste-like anaerobic pipe sealant compound, which contains Teflon®. The product cures when confined in the absence of air between close fitting metal surfaces. This industrial grade sealant develops controlled low strength to facilitate disassembly. Certified to NSF/ANSI Standard 61 for use in commercial and residential potable water systems not exceeding 82°C (180°F). Dripstop® 923 is recommended for sealing metal tapered pipe threads and fittings up to 2 inches (5cm) NPT for industrial applications in the chemical processing, petroleum refining, pulp/paper, waste treatment, textile, utilities/power generation, marine, automotive, industrial equipment, gas compression and distribution industries. It is also recommended for industrial plant fluid power systems.

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.

Instantbond® 110 is a state-of-the-art, single component, solventless, room temperature curing cyanoacrylate adhesive that polymerizes rapidly when pressed into a thin film between parts.

Porosity Sealant (HPS) 991 is the solution to leak proof parts, improving machinability, in addition to increasing the durability and surface quality for painting and plating. The required addition of HPS Initiator 91 activates HPS 991R enabling the system to cure at elevated temperatures (HPS 991). 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.

Gasket Replacer 906 is a single component room temperature cure gel-like anaerobic gasketing compound formulated to provide instant sealing capabilities.
