Two of the more common 2K coatings systems are polyurethane and epoxy. This and next month’s Formulating with Mike column will concentrate on urethanes, with this issue focusing on polyurethane polymers. 

This article examines the physical properties of polyurethanes and polyureas, their differences, and a technology review with benefits and drawbacks of sub-coating classes.

This study introduces the use of 1,3-Propanediol (1,3-PDO) in polyurethanes as a building block component of polyester and polyether polyols, and as a chain extender. The bio-based coatings prepared in this investigation provided useful physio-mechanical properties, chemical resistance, and water resistance compared to reference commercial petroleum-based two-component PUDs.

We currently use a "midnight black” wrinkle powder coating supplied by a major powder producer. Can a second touchup coat be applied after the first coat has cured? Read the answer to this question and more in this edition of Ask Joe Powder. 

New and stricter regulations on the use of certain chemicals can pose significant operational challenges for industry. In printing inks, the use of PTFE is being impacted by new PFOA regulations in Europe as well as Japan and the United States.

In a PCI interview, Christina Mahally of Dow Polyurethanes discusses polyurethanes, how they are used in coatings and other industries, and the current market climate.
