PPG is used in many polyurethane formulations. [7] [8] Synthesis of waterborne polymers has been a feature with this substance. [9] As the basic building block is propylene oxide, there are 3 carbons per oxygen on the backbone. This confers some degree of water miscibility though not as good as ethylene oxide based molecules.

[1] [2] Water-based acrylic polyurethane enamel paint is currently the most widely used paint for reasons including reducing paint's environmental impact. Modern automobile paint is applied in several layers, with a total thickness of around 100 μm (0.1mm). Paint application requires preparation and primer steps to ensure proper application.
Polyurethane dispersion, or PUD, is understood to be a polyurethane polymer resin dispersed in water, rather than a solvent, although some cosolvent may be used.Its manufacture involves the synthesis of polyurethanes having carboxylic acid functionality or nonionic hydrophiles like PEG (polyethylene glycol) incorporated into, or pendant from, the polymer backbone.
