I have to admit that yesterday, while wiping up still more DOTP (dioctyl terephthalate)off the floor, that this was something that 5 years of grad school did not prepare me for.
I've been working with a sprayer system this week for spraying a 2-part polyurethane. DOTP is used as a flushing/storage fluid in the tank as it won't react with either part A or B, it has low volatility and is nonflammable. But since the sprayer had sat idle for 2 years and wasn't cleaned real well before that interval, there were a number of plugs/constricted hoses, joints, etc that need to be removed and cleaned. The geometry of the machine prevents containing all the fluid, much as you can't change a bathroom faucet without spilling at least some water.
So it was flush, clean, flush, clean. I think we might finally have it all cleaned so that we can actually spray what we want, but we shall see. This is my third solid day in grubby clothes. I'll be happy to go back to the normal business casual anytime.
Everything flows, but only the macromolecules are worth the time.
