Hernon® HPS Activator 4322 is used to activate Hernon® Hernon Porosity Sealant (HPS) resins. HPS resins cures to form a thermoset polymer when exposed to elevated temperature. Thermal content and coefficient of thermal transfer in the workpieces influence the cure rate of the HPS system. Higher temperatures produce quicker cure rates. HPS resins generally cures within the range of 177°F (80°C) to 205°F (96°C). Proper cure requires the workpiece to uniformly attain full cure temperature. Parts that do not transfer heat well will required longer processing times. Efficient thermal conductivity yields shorter processing cycles. Parts with heavier cross sections require longer exposure at heat to attain sufficient temperature internally. Carefully consider part geometry. Consult Hernon® Technical Service for specific process requirements.
