I came into a situation earlier this week that needed me to fill in a mistake I had made. I had drilled a hole too large and wanted to fill it in and try again.
I decided that a mixture of epoxy and milled glass (flox) was the way to go. I had a pound of the glass in an airtight container in a cabinet. I purchased it from Aircraft Spruce in April. I decided to shoot for a peanut butter consistancy which I slowly mixed into an already mixed cup (1/1 pump) of epoxy. Once I had the desired consistancy I spread it over the area, filling the holes. After 36-hours it had still not set. The cup of mixture was not set either. It was still just like it had been when I mixed it.
Yesterday I tried again, this time shooting for mayonaisse consistancy and after 24-hours I have a similar situation. It is harder than the peanut butter was after 24 hours, but still mushy. BTW, I mixed a control cup of 1 pump ea with no filler and it is hard as a rock this morning. My garage is about 73 degrees and it has been rainy here in north Texas this week. I cant find anything on the West site.
Is this normal? With a filler added to the epoxy is the setup time drastically longer than no filler? Clearly I am doing something wrong. I dont remember having this issue at the Sport Air class.
My purchase history says that I bought milled glass, not flocked cotton from AS. Looking at it with a jewlers loupe I am certain it is glass, so I dont think it is the wrong product.
