Hi, The ice water is used as it slows the themochemical reaction the epoxy resin. The resin used for this video is a fast setting resin as we were working in a studio and could not use a boiler to force cure a slow reacting resin. The work time of this resin at 20 degrees is only 15min and ambient cure at 3hrs. Usually a resin of between 40 min to 1 hr work time is used for inversion lining installations to prevent hot (cooked and hardend sections) spots in the liner as when its loaded into the drum it becomes a mass and will heat up if not installed in an expedient manner. Slow resin can be force cured in under 1hr and 24hrs for ambient cure.
That's pretty cool
Was that a tub of water to keep it cool?
