RR Epoxy temp/cure times

General Discussion
1

anyone tracked there use of RR Epoxy to give good guidelines for work time and time to flip (cut lap) for different temps (w/ different speed hardner).

I’ve only used the slow hardner in 90+deg weather. Will be building in SoCal during the winter.

How cold can you use RR?

Gregg do you have a chart? (temp/hardner/times)

thanks

Switching to fast in the winter will bring you similar result to slow in summer. I don’t have a chart but off the top of my head in 90¼ with fast I can flip in about 2 hours. At 80¼ it goes to abour 3 and at 70¼ your looking at 4-5 hours. I’ve used the stuff down into the 40’s but I like to heat the laminating area and keep things around minimum 70¼. Everything just works better that way. For all the times above double them for slow.

is flip time a good guideline for time-to-cut-lab as well?

thanks
