Hi.I worked on this paint.pigment stability related on epoxy resin that you used.
Hi Neda. Thank you for your answer. I used Bisphenol A epoxy resin. Which parameter do you mean on epoxy resin?
epoxy resin cured with amine hardner
I know about that but still I have problem with the pigment stability and appearance of crossover area on epoxy floor coatings.
You must used dispersion additives for dispersing and wetting of pigments.epoxy resin that you used must be low viscosity.maybe your pigments are not suitable for this paint.you dont say your problem clear.
