How can I increase the UF microcapsules resistance to breakdown in alkaline condition?

15 November 2022 1 194 Report

Greetings dear researchers,

I have fabricated urea-formaldehyde microcapsules for the dispersion in waterborne polyurethane. However, I found out that the waterborne polyurethane have pH 8.56 in liquid state. So, one of my plan is to increase the microcapsules resistance in this pH state. How can I do that? Any suggestion?

Thanks

Good day, Wan Mohamad Ikhmal! Hope you are doing well.

What is the reason you need to disperse UF microcapsules in waterborne PU? Maybe we can find a solution by changing constituents of microcapsules or substituting waterborne PU with an alternative possibilities. Could you please provide some extra information you can share, to make further research easier?

Yours sincerely,
