Anything is possible, but I know what I used and saw, Tom. It was a small squeeze tube labeled "silicone dielectric grease".
I was the only person that serviced electronic equipment in that company where I worked full-time. I put that stuff on an expensive feed rate switch on an Allen-Bradley CNC mill control, after replacing that switch a number of times. Very soon afterwards (a few weeks instead of perhaps a year), the operator called me over to show me the problem with that switch. I know what I saw, and I am convinced that it is abrasive. That grease accelerated the failure of that switch by a tremendous amount. I should point out that that switch got manually rotated throughout its full range many times per day by the machine operator. "According to Permatex's own information Dielectric Tune-Up Grease contains up to 10% (by wt) of silicon dioxide (silica). This is a very effective abrasive, and although Permatex claim it is not microcrystalline silica, larger particle sizes will only grind the silver plating off rather than polish it off". http://forums.qrz.com/showthread.php?301386-RF-Roller-inductor-maintenance&p=2271612#post2271612 73, Mike www.w0btu.com On Sun, Nov 24, 2013 at 12:40 AM, Tom W8JI <w...@w8ji.com> wrote: > Silicone dielectric compound ("grease") should not be used as a lubricant. >> It's actually somewhat abrasive. >> >> > I think you had something else going on, Mike, or you did not use the > stuff being sold as dielectric compounds. > > http://en.wikipedia.org/wiki/Silicone_grease > _________________ Topband Reflector Archives - http://www.contesting.com/_topband
