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 solution to leak proof parts, improving machinability, in addition to increasing the durability and surface quality for painting and plating. HPS 990 is also excellent for sealing leak paths in rigid electronic assemblies. The hardened resins exhibit superior chemical resistance and elevated temperature stability. The microscopic voids, where potential leaks occur in the part are filled by the low viscosity resin during vacuum application. Sealed micropores cure without shrinkage to form tough cross-linked thermoset polymer, permanently sealing the piece. Excess residual adhesive is washed from the part surface during rinsing with water. The parts leave the impregnating process without surface residue and can then be used in production within a few short hours. The resin polymerizes, sealing gaps in any assembly. This protects electrical components against leakage from air, water, coolants and oils. 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) 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.

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.
