The surfactant-free sealants ease washing impregnated parts and eliminate costly pretreatment of disposed waste rinse water. The sealants seal microscopic voids through a vacuum-application process, which eliminates microscopic voids that cause leaks under pressure. HPS has a lower viscosity resulting in less residue on parts and better sealing of smaller passages. Improved washing eliminates trapped material in blind holds and allows for immediate painting or plating.
