Why are Interior Can Coatings Important?
Metal can interiors are prepared and coated to prevent corrosion & to maintain freshness for a variety of foodstuffs and beverages. These coatings have traditionally been derived from epoxy resins, but they offer little to no chemical resistance in the final performance. Eastman’s cycloaliphatic intermediates (CHDA and CHDM) exhibit an exceptional balance of both delivered hardness and flexibility for premium protection.
When it comes down to brass tax, the numbers don't lie. The table below details several key metrics in coating performance between AD, Eastman's 1,4-CHDA and PIA in a polyester-melamine enamel (Resin:NPG/TMP/Diacid/PIA [1.97/0.30/1.00/1.00]). Learn more about Eastman's CHDA ►
