Ive frozen MAS medium, but only overnight. It didnt crack, but it did feel like it was cured until I rewarmed it. With added heat, I could get it to about the same viscosity as it was before I froze it. Pot life was a little shorter though, but not enough to be a problem. It's kind of handy if I know I will need more the next night; I can mix a bigger batch which is more accurate, and if there is a cure problem, I'll know it by the next evening before I use the frozen part.

: hey, thought I'd make a post about my findings... I mixed up about an once of
: west system slow epoxy, and put it in a container so there was about a
: quarter inch sitting in the bottom, and I threw it in the freezer. it has
: been in there for a week now, and I went to check it. At first I thought
: it was fully cured, because I could crack it. but to my surprise, after I
: warmed it, it became liquid again. so I guess west system freezes solid
: "or atleast solid enough to crack" My aplication for this will
: be with fibreglass tape. I will wet it out then freeze it. after it has
: been frozen, it will be stiff and not tacky. "I'm going to make ribs
: for a SOF with kev carbon ribs"

: any one else tryed this with faster setting epoxy's? or other brands? I want
: to know if all brands do this. I may want to use a different brand of
: epoxy for my boat.
