Detail/Description

PRODUCT DESCRIPTION
HERNON® Porosity Sealant (HPS) 990 is the solution to leak proofing parts and improving machinability in addition to increasing the durability and surface quality for painting or plating. The hardened resins exhibit high chemical resistance and temperature stability. 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 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 within a few hours. 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 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.
