MEKP CHART (Resin Hardener)=how much to use when fiberglassing

[s1795so2]

I figured I would post up the chart, I have used for years before I pretty much memorized how much hardener to resin I need. This is for all you guys who know how to frame up a fiberglass box, but do not know how to mix up the resin.

The chart is based on temps of around 80 degrees average.

the colder the tempature is the more % of mekp you will need,
I started out always using the chart of the CC wich is easy and cheap to do; its the same as a babies medicine spoon, until I could afford the mixing cup, which is easier and most accurate.


ex:
90 degrees and higher = 1% of mekp
70 degrees to 89 = 1.25% of mekp
60 degrees to 69 = 1.50 % of mekp
59 degrees and below = 1.75% of mekp

I rarely actually measure anymore, of course I learned from doing auto body work. Good info

I have memorized the chart now and rarely have to use it, but I still measure.
I have the cup that already measures cc's.
This is what I use, and it helps a lot
