High Productivity and Performance Polyaspartic DTM and Two-Coat Systems

High Productivity and Performance Polyaspartic DTM and Two-Coat Systems
Available for download

These case studies are presented demonstrating the cost savings and performance of one-coat direct-to-metal (DTM) and two-coat polyaspartic exterior coatings of three industrial maintenance applications involving hopper railcars, bridges, and an exposed steel beam superstructure. In each example, the rapid cure time of the polyaspartic coating provided increased productivity to complement its documented high performance.

These case studies are presented demonstrating the cost savings and performance of one-coat direct-to-metal (DTM) and two-coat polyaspartic exterior coatings of three industrial maintenance applications involving hopper railcars, bridges, and an exposed steel beam superstructure. In each example, the rapid cure time of the polyaspartic coating provided increased productivity to complement its documented high performance. For example, fifty hopper railcars were coated in 2002 using a one-coat DTM polyaspartic formulation at eight dry mils. After 11 years in field service, the railcars were examined for corrosion resistance and weathering performance. The increased productivity and cost savings of the polyaspartic formulation versus a traditional two-coat epoxy/polyurethane coating was documented and will be discussed. A second case study discusses shop-applied polyaspartic coating replacing a traditional three-coat system on structural steel supporting the signature atrium of the new Marine Corps Museum in Quantico, VA. The final case study examines the 10 year-long performance of a field-applied two-coat polyaspartic coating replacing a traditional three-coat system on a bridge. Attendees will learn about formulating principles of polyaspartic coating that enables their longevity in the field, and the technical and performance benefits of two-coat polyaspartic systems versus traditional three-coat zinc/epoxy/urethane. Finally, the cost benefits of using polyaspartics to reduce the number of coats in both DTM and two-coat applications will also be discussed.

In 2003 Connecticut Department of Transportation (DOT) conducted a study to quantify the throughput and cost savings potential of a PAS two-coat system versus a three-coat system. The study showed that a PAS two-coat system had a 31% increase in productivity and direct cost savings of approximately $6 per square foot, with indirect cost savings of $18 per square foot when including the benefits of reduced traffic congestion.17 PAS two-coat systems utilize a zinc-rich primer for galvanic protection; the epoxy and polyurethane layers are replaced by a high-build PAS topcoat.

Polyaspartic coatings can offer excellent performance characteristics typically expected of SSPC Specification Number 36, Level 3, for Aliphatic Polyurethane Topcoats. In addition, polyaspartates will pass an industry standard for corrosion protection in medium corrosivity environments direct to metal. These features offer the typical industrial maintenance customer high performance for gloss and color retention, while reducing application time and costs.

Recent advances in the realm of polyaspartic ester finish coat technology have led to significant improvements in their aesthetic and corrosion resistance properties. Of particular interest is an initial comparison of the aesthetic properties of older and new generation polyaspartic ester finishes with both polyurethanes and isocyanate-free polysiloxane finishes.
