Formulations

Porosity Sealant (HPS) 41814 is the solution to leak proof parts, improving machinability, in addition to increasing the durability and surface quality for painting and plating. 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.
