Editor’s note: This is the last in a series of stories about what Eastman makes. KINGSPORT ‑ One product made by Eastman makes paint tougher and food safer. Eastman Tetrashield protective resin systems create protective coatings that enhance appearance, improve weatherability, and bolster scratch resistance for cars. In fact, in lab tests, coatings formulations with Tetrashield show significant durability and aesthetic enhancements when compared to coatings using other resins, according to Eastman. Tetrashield is also used as a coating inside food and beverage cans to enhance food safety. You might not ever notice it, but it is also used on large structures like bridges and water towers. In simpler terms, it makes paint look better and last longer,“ said Charlie Giaudrone vice president and general manager, Eastman Coatings & Inks.
