cncdoc Posted March 21, 2004 Share Posted March 21, 2004 I know I read somewhere about the TG of Epoxies (particularly MGS) The 285 tg was well over 200F whereas the 335 (cheaper) had a tg of 140 to 180F If I remember right, this had something to do with the post cure temps. The general idea I got from the whole thing was that if you post cure the epoxy at xxxF (temperature) then it will remained cured (hard) at or below that temperature for the rest of it's life. The "expert" in question also spouted rheotoric to the effect that cure temps over 200F were unrealistic in real life and somewhat overkill, as it would be difficult if not impossible to cure at upper tg without melting stuff (foam i'd imagine). I tried the search engine here, but it's been drinking and wouldn't give me a straight answer and insists on making me play my "wildcard". But I had it hands down with a "full house" and a "straight"! It misdirected me on purpose and landed me square in the middle of a sanding discussion. I countered with another "wild card" and it "saw" my play and raised me into the "engine discussion" area. I folded and lost the kitty. The cards were marked. I accused it of cheating and drew my "9" first! I then realized I was about to shoot my laptop. So I decided to circumvent the dishonest gambler search engine and plead my case here. computers always win anyway. unless you shoot them first.
