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.

Hello and thank you very much for your reply.
I can confirm all the above questions. I keep all my working conditions pretty strict, temperature 23, humidity 45, as this is not a hobby project, it is my occupation. It is just the first time I am using this product.  This resin was purchased last week(the 5kg pack with combined hardners), and I did understand the way it is supposed to be mixed, which by the way, i find it genious and helpful that you can control your pot life, according to your surfaces you laminate.
The mix i was using in my case was 40(20+20 slow and fast) hardner + 133 resin, but i have tried others just to see if there is any difference. The flakes that form are pretty solid, an can be picked up after brushing the resin from the flat surface, I will try to make some photos later if i m making a new mix, but to give an ideea, they look like very small pieces of paper soaked in resin. 
Thank you once again for your help.
