Product Description

UPAC: 2,2-Dimethyl-1,3-Propanediol

Eastman NPG™ 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.

In the United States, neopentyl glycol may be lawfully used as a reactant for coatings and other products intended for use in contact with foods under specific federal food additive regulations. Contact an Eastman Technical Service Representative for more details.

Eastman NPG™ glycol is available in three forms:

  • Platelets in bags that exhibit excellent caking stability on storage.
  • Bulk molten shipped in tank trucks that require a heated tank for storage.
  • Eastman NPG™ 90 glycol, a liquid at or above 38°C containing 90 parts NPG and 10 parts water, is delivered in bulk and can be stored at a much lower temperature than molten NPG.

For more information or to request a sample, contact an Eastman Technical Service Representative.
