Sherwin-Williams Protective and Marine Coatings has launched Envirolastic 980 PA, an advanced high-build polyaspartic urethane coating delivering rapid return to service and one-coat exterior durability.
According to the company, because of its high-build properties, Envirolastic 980 PA eliminates the need for the two-coat application over a zinc-rich primer that has been the industry standard for decades. Performance requirements can be achieved without the intermediate coat. In addition, the product offers curing even in low or humid temperatures, abrasion and corrosion resistance, and high gloss retention. Up to 9 mils dry film thickness is possible in just one pass.
The coating dries to touch in 30 minutes and an asset can be returned to service in two hours when applied at 77 F (25 C). This compares to the more typical two coats that require two eight-hour worker shifts with significant nonproductive time in between coats, and return to service times that vary widely with the environment in which it is being applied. Envirolastic 980 PA is also suitable for use on sports facilities and other high-visibility structures.
