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) 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.
