SELECTION BASICS
“Waterborne polyurethane” is only the starting point
In technical discussions, PUD commonly refers to a polyurethane dispersion. The label “waterborne,” however, does not define a fixed hardness, durability level or surface effect. Selection still depends on polymer design, coat position, film character, ionic character, solids, substrate and the end-use test requirements.
