how to prevent resole phenolic/urea (60/40) "from the suspension .??

[panu...@gmail.com]

I have study the synthesis the resole liquid phenolics resin with the addition of urea (ratio 60:40) but after i kept it in the shelf ,It will suspense after several days.

I need to know the mechanism of it or how to fix it (It's not going to happen when no add urea)

Although, good chemistry is important in any open source project. 😁
