"Ultimate scratch resistance is provided by the Armstrong™ Lifetime Finish. Nano particles in the finish create a powerful layer of scratch protection without clouding the beauty of the hardwood beneath." (see pg. 8 of Performance Plus Hardwood Brochure)
"Armstrong Performance Plus is a brand new collection of engineered hardwood flooring that is infused with liquid acrylic to enhance durability and resist dings and dents to a level unparalleled by traditional hardwood floors. They are 2.5x harder, even harder overall than exotic hardwoods. This collection even surpasses Armstrong Premier Performance, with increased scratch resistance and a clearer coating (due to the nano Aluminum Oxide finish)."
