How Do I Choose the Right Epoxy?

Nice to hear you had some good results what hardener did you use?

Hey Kyle,

I used the Tropical 260, with the medium viscosity resin.

I hope to do the second run this week, weather permitting. i will keep reporting what happens in the Kurt Hughes thread in the boatbuilding forum.

Thats good to hear. I was actually planning on giving you a call later this week to ask how the new tropical was working out for you.
Glad everythings good if you need anything give us a call or send me some ideas on it.
Happy boat building
Kyle

 

QUESTION:

I have some System Three epoxy in my vacuum bag right now, bagging scarf joints (sorry, Kyle... ).

I'm using System Three Hardener #3, which is the slowest. It has a "tack free time" of 8 hours at 25C. It's 99 degrees in the shop (37.2C).

The epoxy has been under vacuum for 5 hours.

When can I take the bag off???

 

Now...

 

Simple guide is when the wall of your mixing bucket has gone tack free, I assume your 8hr tack free time at 25'C is the thin laminate gel time then at 37'c this would have been just under 4 hrs.
Congratulations, it must feel good to have started the build.
