AZO77HSA is an exceptionally small particle size French Process in powder form, statistically measured zinc oxide formed from zinc metal. AZO77HSA was explicitly developed to have the highest viscosity, reactivity, purity, and fineness. This grade is used in can sealants, latex compounds, zinc chemicals, plastics, paint/coating, and in the food can liner coating industry where the particularly fine particles freely convert certain accessible soluble into white sulfide, thus avoiding discoloration of food from sulfides of tin or iron. AZO77HSA is available with surface treatment (AZO77HSA-T), has a surface area range of 8.0 to 10.0 m2 /g, a specific gravity of 5.6, and an apparent density of 20 to 40 (lbs. /cu. Ft.).
U.S. Zinc is the premier global leader in the added value zinc products market. U.S. Zinc manufactures zinc oxide from high grade (HG) and special high grade (SHG) zinc metal as well as from zinc secondaries. With plants in Brazil, China, and two in the United States, they are the largest producer of zinc oxide in the world, providing supply security across the globe. U.S. Zinc also produces zinc dust from high grade (HG) and special high grade (SHG) zinc metal as well as from zinc secondaries. Some of their products have greater surface area and are used by the paint and coatings, latex, plastic, and zinc chemicals industries and in applications.

Lists combine the ease of Bookmarks with the versatility of Tags. Instead of one collection of bookmarked items, create as many collections, called "Lists," as you need.
Find the link to your List page in the user menu.
All Tags have been converted to separate Lists, and your bookmarked items have been saved to a "Bookmarks" List.
When you click the Add to List button, a dropdown of your existing Lists appears. Click the List name to which you want to add this product or formula.
You can also create a new List. Simply click "Create a New List" and enter a name.
When you define a new List, the current item is automatically added to it. You can add a product or formula to as many Lists as you need.
Easily see which Lists this item appears in, and quickly go to that List from the links that appear on the page.
