| Product Description: Eastman NPG™ glycol is the industry standard glycol component in high-quality polyester resins for industrial coatings and fiberglass-reinforced plastics applications. Most polyester resin formulations contain NPG as the sole glycol component, or it is used in conjunction with a modifying glycol to achieve desired properties. NPG and Eastman™ PTA (Purified Terephthalic Acid) are the primary components for polyester powder coating resins. Eastman NPG™ delivers the overall toughness, stain and detergent resistance, and outdoor weathering performance required of coil coatings for appliances and products for exterior applications. Gel coats containing unsaturated polyesters made from NPG and Eastman™ PIA (Purified Isophthalic Acid) provide excellent weatherability and water and stain resistance. Eastman NPG™ is also used in polyester polyols for polyurethane coatings for the automotive, industrial maintenance, transportation, and aerospace markets. Application/Uses: - Automotive OEM
