I added a little Xylol (AKA Xylene) because I thought I saw it listed in an MSDS for coil dope. However, the MSDS for the General Cement product lists only MEK although the thinner is Toluene. If I do it again I will use straight MEK. I added the styrofoam until the stuff got to what seems to be the right consistency, about like honey. A word of caution to anyone considering this: when starting this procedure, fill the container only a third of the way with MEK. All that polystyrene needed to thicken it up to honey-like consistency will increase the volume a lot. I have a half-pint mason jar that started with a third of MEK. I fed it one and a half letter-sized inch-thick slabs of foam and it's still not done. -- David Griffith --- Put my last name where it belongs I started with about half the jar filled with MEK. Since I used styrofoam the displacement of the material before it dissolves is much greater than after because so much of it is air. The first pieces dissolved very quickly, in fact it looked like Alka-Seltzer dissolving. Toward the end it took a few minutes for each additional piece to dissolve. The total amount is amazing until you remember that its mostly air. After the first flurry of very quick solution I added pieces about twice a day and just let it alone between times. Of course with the cap on, MEK will evaporate very quickly. -- Richard Knoppow Los Angeles WB6KBL |
