Isocyanates react with compounds that have active hydrogens. For example, in coating applications, isocyanates are typically reacted with polyols to form polyurethanes, or with primary and secondary amines to form polyureas. Catalysis of the polyol/isocyanate reaction, which is often required to develop sufficient cure response, can be achieved with a variety of compounds.

With increasing consumer demand for convenience comes greater demand for high performance standards and increased sustainability. The packaging industry is no stranger to these trends taking place with consumer products across the world
What are some fundamental issues that I should know regarding the basics of formulating coatings?
May 1, 2015
An important concept to learn is critical pigment volume concentration (CPVC). Understanding this concept is essential for formulating high-performance coatings. In fact, it’s an “elephant in the room” for many formulators—ignored at our peril.
Hot-melt pressure-sensitive adhesives (HMPSAs) have become important in the manufacture of pressure-sensitive labels. Several types of styrenic block copolymers (SBCs) are used to formulate HMPSA adhesives.
I hear many salespeople complain that their product has become commoditized. This can be one of those “perception equals reality” traps; that is, if you believe your product or service is a commodity, then you are helping to make it a commodity.
The current laminating industry mindset is to simply try anything. Many manufacturers have started to realize that creative combinations of unexpected substrates might fill untapped demand for finished products that look and feel novel, are extra sturdy, or display other desirable properties that are unattainable with standard materials.
Pressure-sensitive adhesives professionals from around the world will convene May 11-15 for this key tape industry event.
