Multiple applications of Polyurethane Dispersion

Otto Bayer is a world-renowned scientist for its ultimate discovery of polyurethane dispersion. In its previous days, people were doubtful of his new ideas of combining different chemical substances and obtaining dry foam materials. However, the discovery of polyurethane dispersion by Bayer has changed the people’s viewpoint towards him. He was the person who discovered the basic process of diisocyanate polyaddition. Today’s chemical industry must deliver tribute to him for his amazing chemical inventions.

There are numerous applications of polyurethane dispersion. Do you know all types of foams are made from polyurethane? Flexible foam is used in upholstery; rigid foams are placed inside the walls of refrigerators and freezers. Flexible and semi-flexible foams are also used in manufacturing car seats, head rests and arm rests.

The reason why polyurethane dispersion is of immense use in today’s industry is that it is the most suitable and safest replacement for solvent based coatings because they are known for their environment friendly property. Another benefit is that they come in a great range of hardness and solid content. Their zero to low volatile organic content enables their formulation into a compliant coating for many different substrates. Polyurethane dispersions are fully reacted polyureas of small and discrete polymer particles ranging from 0.01-5.0 microns in a continuous water phase.
