What are polyurethane adhesives & coatings?

This publication is licensed under CC-BY 4.0 . Polyurethane (PU) adhesives and coatings are widely used to fabricate high-quality materials due to their excellent properties and their versatile nature, which stems from the wide range of commercially available polyisocyanate and polyol precursors.

Who invented polyurethane?

What initially sounded like a crazy idea quickly took hold. The chemist Otto Bayer, who was born in 1902, developed the first polyurethane in 1937 and registered it for patent. Today, his invention has become an indispensable part of everyday life. Otto Bayer demonstrates a foam test with polyurethane during a lecture.

Why are polyurethane adhesives formulated as two-component reactive systems?

To avoid viscosity issues, polyurethane adhesives and coatings were initially formulated as two-component reactive systems by mixing low molar mass or oligomeric raw materials, which contained free isocyanates and/or alcohol moieties.

How big is the polyurethane adhesives market?

Currently, their annual worldwide production exceeds 20 million tons and accounts for about 7 wt % of all plastic production. (1) The polyurethane adhesives market size was estimated at 7.0 billion USD in 2019 and is projected to grow to 9.1 million USD by 2024 (at a 5.6% compound annual growth rate).
