Hernon Porosity Sealant (HPS™) 1000 & 1100
Low Vicosity - Improved Washing From Surfaces, Sealing of Smaller Passages Substrate Lubricity - Increased Dimensional Control in Machining, Reduced Tool Wear Hydrocarbon Solvent Resistant - Resist Degradation by Gasoline, Motor Oil, and Transmission Fluid Flourescent Dye - Rapid Examination of Processed Components Rapid Cure - Limited Delay in Production Process Hernon Porosity Sealant (HPS™) 1000 and 1100 represent a break through in sealing leaking porous metals such as powder metal castings and sintered metal parts. HPS™ 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. The addition of florescent dye allows for rapid examination of parts to check the thoroughness of the impregnation process. HPS™ 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™ 1000 and 1100 end this problem by sealing the microscopic voids through a vacuum application process.
The machining properties of parts impregnated with HPS™ 1000 and 1100 is greatly improved because of factors including 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™ 1000 and 1100 also greatly increases the life of tools by lowering tool to part friction, therefore lowering costs.
HPS™ also increases the ability of rapid parts inspection. Included in each HPS™ is a fluorescent dye, which reveals the filled pores under a black light.
The lower viscosity of HPS™ 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.
"Hernon Porosity Sealant (HPS™) has been good compared to the last supplier we used. We were able to reduce our production cycle from 20 minutes per basket to 10 minutes per basket." - Richard Stewart, Senior Manufacturing/Environmental Engineer, Volvo Penta Marine Products, L.C.
