Out of curiosity I started searching for mixing ratio's for MEKP to Resin to see what other people are mixing it at for higher air temps.
All most all charts and info I found all give the 1% mixing ratio at 75*f. If I used that ratio in our hot summer months here there would be no working time before the resin cured.
None of the info gave adjustment for Air Temperature or Humidity.
Then Came across this.
These charts list suggested ratios for higher temps. I've been using ratios close to these in the hot summer. (1/2% - 3/4%) with good results
