Zoukeimura spray & humidity?

I searched for awhile trying to find an answer for this but I can't seem to find one. I've read a lot in the past that you shouldn't use MSC in humidity levels over 60%, but what about zoukeimura finishing powder spray (UV cut if it matters)?

 

There seems to be a lot of info about what temperatures and humidity levels MSC works best at but not for ZM which I ordered recently. I asked Volks USA and they said it isn't that sensitive to humidity but couldn't give me a direct number.
