Subject: [FlyRotary] Epoxy
Question for you glass fellows. Yesterday I
laid up some cloth on the cowl and it didn't harden. I put some
heat on it with the heat lamp and left it over night and nothing. This
morning I put the heat lamp on it and pulled it off, scraped it and
ground the area, wiped it down again with acetone and tried again. The
epoxy is United Resin Corp. Uni-Lam. The shop is hot water heated with
pipe in the floor and this epoxy is supposed to work at room temperature..The
ratio by volume is 1 to 3.8, it has been working ok by using a marked
stick in a soup can, but I'm wondering if this ratio is hyper critical.
Any input would be greatly appreciated. JohnD
Since you are using the volume
method of measurement, you might try using the pumps that West Systems uses
and are available in 3:1 ratio which should work fine for a 1:3.8. If you
wanted to get closer, just hit the resin pump for a few more drops.
These pumps are cheap and I believe
Wicks and ACS sells them. I use them all the time.
