Hello  wonderful list,

  

 I just  purchased 5 lbs of glass micro to be used for filling movable wing  surfaces. Having made some ding resistance and sanding tests with differing  resin amounts, and to prove it is sandable (at least half as sandable, timewise,  as superfil...depending on amount of resin added) , I see that the manual  suggests to use thermoplastic spheres instead of the glass ones. My favorite  aircraft mail supply shop does not seem to carry them. So I ask...what is wrong  with using standard Aeropoxy and glass micro?  I have no experience  in filling surfaces so far,  so any help is  appreciated.

  

 Regards,

  

 Greg  Fuchs

I think the answer may be weight.



The glass version being heavier than the thermoplastic.

I seem to remember that Europa also said the thermoplastic filler is easier to sand than the glass microspheres (providing you get the mix right).

Both are true, Expancell is lighter and easier to sand, especially if you lubricate the resin with Cabosil (colloidal silica) and increase the micro to resin ratio. Check it out with a small sample. You'll be amazed how much more Expancell will mix into the same amount of resin. The silica seems to reduce the surface tension of the resin and makes it wet the balloons better.

Thank you for all the responses. Graham, I will have to  try the colloidal silica along with the thermoplastic filler. BTW, where in the  states is the best way to get the thermoplastic stuff? I have not seen Expancell  listed in the main supply houses. Is the SUP*R-FIL solution similar to  Expancel? Can it be obtained in the 'micro' form for example, without the binder  pre-mixed with it?
