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) 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.

ReAct® 795 is a tough acrylic adhesive designed primarily for securing of ceramic permanent magnet segments in motor magnet bonding applications. This adhesive has also found wide acceptance in a variety of structural bonding applications due to its versatile performance capabilities. ReAct® 795 has demonstrated the ability to provide high tensile strength while maintaining excellent product flexibility. This results in tough, durable bonds with outstanding impact and peel resistance. This tough acrylic is a single component, room temperature curing adhesive which is used in conjunction with Activator 47. Additionally, exposure to a high intensity UV light will cure this adhesive to a dry, hard surface. ReAct® 795 is similar in function to Loctite A533 and Loctite AA332 and delivers high shear strength and tensile strength. One of its primary uses is securing permanent magnets in motor magnet bonding applications. Recomended Applications: Furniture | Elevators | Automotive Applications | Permanent Motor Magnets | Speakers | Generators | Bonding Flywheels | Sensors |

Self Locker 523 is a pre-applied micro-encapsulated adhesive for threaded fasteners. Self Locker 523 stays dry-to-the-touch until the shearing action of an engaging nut applied to the coated bolt causes the capsules to break allowing the adhesive to cure. This material securely locks and seals against vibration loosening and fluid leakage.
