HPS Porosity Sealant 41814

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.
