Porosity Sealant (HPS) 38374R 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 activates the dual-cure system enabling the system to cure anaerobically at room temperature or at elevated temperatures. The cured, hardened resin exhibits superior chemical resistance and elevated temperature stability. The microscopic voids, where potential leaks occur (between metal grains or ceramic or plastic molecules) in the part are filled by low viscosity resin during vacuum application. Sealed micro-pores cure without shrinkage to a tough, cross-linked, thermoset polymer, permanently sealing the work piece. Residual adhesive film is washed from the part surfaces by water during the rinsing cycle. The parts leave the impregnating process without surface residue and can then be used in production within a short period of time. When used in preparation for plating or painting processes, the impregnation process also eliminates absorption of plating material (like acids) or painting prep solvents that could otherwise bleed out of the pores causing finishes to discolor, blister, pit or peel. Sealed powdered metal parts exhibit better machinability, enhanced tool life and better dimensional control.

Porosity Sealant (HPS) 59801 is a low viscosity liquid sealant designed for sealing interfacial leak paths in flexible electronic assemblies. It may also be used to enhance dielectric strength or seal porosity in passive materials. The dual-cure system incorporated in HPS 59801 offers the advantage of elevated temperature curing or curing at room temperature. HPS 59801 is typically applied with a vacuum impregnation process that removes air from the internal void and then saturates the part with liquid sealant. In the absence of circulating air, the liquid rapidly polymerizes to form a tough, flexible, thermoset polymer that permanently seals gaps in the assembly. Excess liquid sealant is rinsed from the outside of the part with an aqueous solution effectively leaving no surface build up. Parts processed with HPS 59801 are sealed internally but remain cosmetically and dimensionally unchanged. Typical applications include sealing or unitizing over-molded electrical components against leakage of air, water, coolants, oils and other fluids. As a good insulator, HPS 59801 may also be used to improve the dielectric strength across gaps between high voltage conductors.

Porosity Sealant (HPS) 990 is the ultimate leak path sealant for porosity, offering a reliable solution to leak-proof parts while enhancing machinability, durability, and surface quality for painting and plating. Ideal for sealing leak paths in rigid electronic assemblies, HPS 990 uses hardened resins that provide superior chemical resistance and elevated temperature stability. The low-viscosity resin fills microscopic voids where potential leaks occur, sealing gaps during vacuum application. These micropores cure without shrinkage, forming a tough, cross-linked thermoset polymer that permanently seals the piece. During rinsing, excess adhesive is washed away, leaving no surface residue and allowing parts to be used in production within hours. When used in plating or painting preparation, HPS 990 prevents absorption of plating materials (like acids) or painting prep solvents, eliminating the risk of finishes discoloring, bleeding, pitting, or peeling. Sealed powdered metal parts also exhibit improved machinability, enhanced tool life, and better dimensional control. Protect electrical components from leaks caused by air, water, coolants, and oils with this advanced leak path sealant for porosity.

Porosity Sealant (HPS) 991R 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 991R). 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.

Porosity Sealant (HPS) 994 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 higher 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.

HPS Porosity Sealant 41814 W/O Activator is the ideal solution for leak-proofing powder metal parts, improving machinability, and enhancing durability and surface quality for painting and plating. This powder metal sealant works by filling microscopic voids where potential leaks occur, whether between metal grains or plastic molecules. The low-viscosity resin is applied during a vacuum process and, when exposed to elevated temperatures, cures without shrinkage to form a tough, cross-linked thermoset polymer that permanently seals the workpiece. The sealant provides superior chemical resistance, elevated temperature stability, and excellent bonding properties. During rinsing, any residual adhesive film is water-washed off, leaving no surface residue and allowing parts to be used in production immediately. When preparing parts for plating or painting, the impregnation process prevents the absorption of plating materials (like acids) or painting solvents, which could otherwise cause finishes to discolor, bleed, pit, or peel. Sealed powdered metal parts exhibit better machinability, enhanced tool life, and improved dimensional control, making this powder metal sealant the perfect choice for high-quality manufacturing.

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.
