Aliphatic Polyurethane are 100% UV protected and also bring the highest form of chemical resistance to the table. You can go with white without having it turn yellow at all. The drawback of this coating is the flexibility. They are not as flexible as the aromatics, but in certain industries flexibility is not needed, such as boat decks and walkways.
In closing, use the aromatics when at all possible, and use the aliphatic when you need a white surface on a non-industrial use such as boat decks and walkways.
