Surfactant-Free Sealant seals porous metals.August 25, 2004 -
HPS(TM) 1000 and 1100 seal microscopic voids in leaking porous metals such as powdered-metal castings and sintered-metal parts through vacuum application process. Both feature resistance to degradation by hydrocarbon solvents, and lubricity that lowers tool wear. Surfactant-free products facilitate washing of impregnated parts and eliminate need for pretreatment of disposed waste rinse water.

Hernon Manufacturing Introduces Hernon Porosity Sealant HPS(TM) 1000 and 1100
Seals porous metals such as powder metal castings and sintered metals
Increased lubricity to lower tool wear
Surfactant free to ease washing of impregnated parts and elimination of pre-treatment of waste rinse water
Orlando, FL August 10, 2004: Hernon Porosity Sealant (HPS(TM)) 1000 and 1100 represent a break through in sealing leaking porous metals such as powder metal castings and sintered metal parts. HPS(TM) 1000 and 1100 also offer other benefits such as increased lubricity, which lowers tool wear and resistance to degradation by hydrocarbon solvents such as gasoline, motor oil, and transmission fluid. HPS(TM) 1000 and 1100 are also surfactant free, which eases washing the impregnated parts, and eliminates the need for costly pre-treatment of disposed waste rinse water.
Many metal components, especially cast parts, are plagued by microscopic voids that allow leaks under pressure. This limits the use of these low cost alternatives in applications that require a seal including transmission housings, engine blocks, and gearboxes. HPS(TM) 1000 and 1100 end this problem by sealing the microscopic voids through a vacuum application process.
The machining properties of parts impregnated with HPS(TM) 1000 and 1100 is greatly improved through increased lubricity, filled voids, and better dimensional control. On non-impregnated cast parts, two factors increase the wear of cutting tools. The voids in untreated materials causes the tools to chatter over the surface that can make more precise machining more difficult and tool wear more rapid. The increased lubricity offered by HPS(TM) 1000 and 1100 also greatly increases the life of tools by lowering tool to part friction, therefore lowering costs.
The lower viscosity of HPS(TM) translates into less residue on parts after the process and better sealing of smaller passages. The improved washing from surfaces will eliminate material trapped in blind holds and allows for immediate painting or plating.
