As you all know, I restore relay boards. Jeff B suggested that I go to using an electrical compound Epoxyseal 9000($40) to seal the relay boards. So, I had 7 boards to seal up. They were all cleaned, tested and ready to go. I had enough to do 4 the old fashion way. All the boards were sealed with silicone in the 4 areas that will leak otherwise and left to dry for two days. So yesterday, I followed the mixing instructions for the Epoxyseal 9000 and set about filling the compound in the back of the boards. Everything looked good when I left them to dry. Went to the warehouse this morning, 3 ruined boards. Best I can tell the epoxy did NOT play well with anything it came into contact with. The epoxy ate the glue off the tape and came out the side of the end and the voltage regulator screws. Guessing it melted the silicone and ran out the voltage regulator plug and the clip lockdown holder. Could not even to begin to peal the tape off the boards. 4 hours, $40 and 3 ruined relay boards
Not sure what you can use to plug up board before pouring the Epoxyseal 9000. Attached image(s)

Really sorry to hear of this Mark.
"Once an epoxy is fully cured, or a silicone is fully cured, they can be used adjacent to each other without any issues." from here: https://www.jpkummer.com/sites/default/file...nteractions.pdf Did the epoxy otherwise adhere well to the board, and did it just ran out the holes? |
