Yes, lots of different epoxies that cure under different conditions. West Systems is good. It's not cheap. I've used lots of different epoxies over the years and I've never had problems with any of them. For a while HD was selling an epoxy in quart or gallon cans that was a 1/1 mixture. I find proportioning the 1/1 mixtures is far easier.
