I thought the context did a pretty good job of explaining it, but if it did not, I am sorry.
Epoxy potting compound is a lot easier to remove than the silicone RTV based varieties... Although the silicone variety starts out soft, it is not crumbly. The epoxy sort loses its cohesiveness with its hardness when hot. If you stick a screwdriver into it, and twist, it pops off decent sized crumbs. What I typically do is take a dental probe that is dull, and slide it between the board and the potting compound, and strip off chunks of the potting material. Or I use small 1/8 inch blade screwdriver and do the same. It goes pretty fast... you avoid toroids, and things with fine wires, of course. The easiest way to remove silicone potting compounds is to take advantage of silicone rubber's voracious appetite for slurping up petroleum solvents. Put the item you want to strip in a container filled with naptha (aka lighter fluid, or fuel) and let it soak over night. By morning, there will be this highly bloated and fractured gelatinous mess all over the board. -Chuck Harris Bob Stewart wrote:
OK, that explains your comment. This is most likely a silicone based potting compound. It's a bit softer than an eraser when cold. Very little of it was actually stuck to the board or components. If it had been a hard, epoxy-based covering, I wouldn't have bothered with it. Bob
