Where to use 3239
A modified polyetheramine for epoxy floor topcoats and construction coatings. It has the highest hardener viscosity of the three DAHUA polyetheramine grades and is worth screening when the crew needs more working time than 3219 offers.
What to check in a trial
Check mixed viscosity and leveling together, especially if the topcoat carries fillers or pigments.
