Their chemistry is very versatile, as is their application and application potential: Polyurethane (PUR) coatings and their typical components – polyisocyanates and polyols – will be reviewed and compared in this tutorial. This includes a discussion of the various PUR coatings technologies in use and their advantages and limitations, such as 1K and 2K solventborne, as well as waterborne chemistries, radiation curing PUR coatings and PUR powder coatings formulations, and their typical end-use applications.
New Hybrid Floor Coating Technology

Time: 10:00 – 10:30 am
Speaker: Chuck Gambino
Great advances have occurred over the years to develop floor coatings that have reduced volatile organic compound (VOC) emissions and fast return to service.
A new UV-cure polyaspartate floor coating technology was recently developed, tested, and field applied to evaluate the application process. The features of this technology include ultra-low VOC’s, high solids, user-friendly working time, excellent chemical and abrasion resistance, high end decorative appearance, physical dry properties, and most importantly fast-return to service.
This presentation describes our Design of Experiment to test raw material combinations to meet a quantified set of requirements for the flooring industry. The optimum raw material combination was then modified further into a coating formulation to both enhance the performance and refine the application properties. Finally, a field application was performed to evaluate the application properties and UV-curing process in a real world environment.
1K PUR Dispersion with Comparable Performance to 2K Waterborne Coating

Two component (2K) waterborne polyurethane coatings are known to have excellent performance properties and are used in a wide variety of applications. However, challenges of 2K waterborne coatings include limited pot life, increased waste, risk of mixing failure and additional process steps before application. Therefore, in some markets, paint formulators look for one component (1K) waterborne coatings that perform comparable to their 2K counterparts. One example is coatings for residential vinyl windows. Vinyl windows represent over 70% of windows sold into the USA residential window market. Consumers want more color options besides just white, and to meet that demand, window manufacturers are painting more windows. This paper discusses the performance properties of a newly developed 1K PU dispersion that has comparable performance properties to 2K coatings typically used to paint residential vinyl windows.
