Re: [PSUBS-MAILIST] Shelsol D60 experiment



Hi Alan,
 
Interesting to hear how the various plastics stood up to D60.  Why would you use mineral spirits (a solvent) instead of light mineral oil as a compensating fluid?

Hi,
A couple of months back I posted that I was experimenting with Shelsol D60 for use as a
compensating fluid for my motors & linear actuators.
This is a low viscosity, low aromatic mineral spirit.
I left polystyrene, acrylic, & bits & pieces of household plastic soaking in it.
I just noticed that after 2&1/2 months the polystyrene had shriveled slightly & sunk.
This was a good result compared with WD40 wich did this to the polystyrene in less than a
day.
The Shelsol also caused some of the cheap plastics to become brittle. The Acrylic, acetate
& some other plastics (not sure what they were) were unchanged.
I haven't tried running my submarine motors in it. But one of my very small linear actuator motors wich
had been soaking in it for the same time frame works fine.
Although the result was great compared with WD40, it's still degrading some plastics & I'll have
to rethink what I'm doing with my actuators as there are electronics inside them that may be affected.
