Chromate-Free Coatings Natural Coating Systems, LLC Muncie, /nd

Natural Coating Systems' RainSeal Coatings are based on water-soluble inorganic components. An inorganic polymer is formed over any surface. The surface may need activation so the seal will bond to it directly. The pH ranges from 1,6 to 4.2 (2,4 to 2.7 is typical). Application t~mperalure is ambient to 120"F, with 100°F for five minutes bemg typical. AquaPro seals
