Hello. Sorry for opening a new topic, i have not found a similar issue anywhere else.
The problem occurs when I m mixing the resin with the combined slow and fast hardner. After thorough mixing, some white flakes start to appear in the cup that float arround. If i mix them separately, the mixing is completely clear. I have tried putting the hardners in the cup firstly and mixing them thoroughly before adding the resin, but with no result, everytime the hardners are combined it is like the resin starts coagulating when mixing.

Picking up where Matt left off, I am still wondering if there are any other factors going on here? 

Your mixing ratio seems ok.  Amine blush is typically caused  by factors such as temperature, poor mixing, slight measuring error etc so maybe tighten up on your processes slightly will help with that.

Can you email or message me the batch?  We get the hardeners in  large  barrels  and IBC's for the resin so batch sizes are quite large.  We have not had any reports of the flakes you have mentioned.

Have the containers been properly sealed?  I have seen white crystalline flakes around poorly shut lids and/or drips around the neck/lid where the hardener  which is exposed to air has had moisture get at it.   It is remotely possible if your environment is very moist you could have the issue in a bottle with the lid left off.
