Hi all, We are facing a porosity problems with some of our Aluminum alloy castings during sealing test. Would anyone suggest some material to seal and block those pores by just wiping on leaking location. I've been advised to use DIPSEAL material HA450, but material is no more available. Operating conditions -40 to 70oC, casting is painted, ESD precautions applied. Regards, Mohammed A.
