G'day all. I'm living in the top end of Oz and its bloody humid at the moment! We are hitting around 70% humidity day to day.
I know resins don't like humidity over 50%, however, with an air conditioner in the room I cast in, I can get room humidity down to about 48%. Surely I'm not the only person to ever have this dilemma. Is it possible to get polyurethane resins to set properly in this climate and if so, can I get some tips and tricks pretty please? Cheers in advance! Jamie Winderlich

Greetings from the other Oz....errr ah Kansas, Dorthy, Toto, the Wizard of Oz... As long as you use the proper mix ratio, I prefer by weight, you should not have any issues as far as relative humidity is concerned. Here in North East Kansas U.S.A we experience the same type of humidity percent's as you do and the heat indecencies can be anywhere from 80 to 100 degrees f. on any given day in the Summer. My hobby room is air conditioned as well, so I have had no issues what so ever with pouring resin, making RTV rubber molds, product storage etc etc. I have poured year round and can not tell any difference from season to season.

3 clicks of the heels and there's no place like home!
Cheers for the info Brian, I've been hesitant to invest in anything in case it was a failed experiment! Do you use normal quick setting polyurethane or a slower setting time?
Cheers, Jamie Winderlich

What I pour is the regular RC-3 for resin.
