Product Description

IUPAC: 3-Hydroxy-2,2-Dimethylpropyl 3-Hydroxy-2,2-Dimethylpropanoate

Eastman™ HPHP glycol, hydroxypivalyl hydroxypivalate, is a difunctional ester-glycol used for manufacturing polyester resins for the powder, coil, and automotive coatings market. HPHP is structurally similar to Eastman NPG™ glycol so they share many of the same structure/property relationships.

Resins containing HPHP impart flexibility to coatings while maintaining weathering and the overall good balance of mechanical properties provided by NPG. Consequently, HPHP is an excellent choice for automotive primer surfacers with increased chip resistance and coil coatings that require a high degree of flexibility and exterior durability. In powder coatings, HPHP enhances the appearance of the coating film by improving flow and leveling during cure without compromising package stability.

Eastman™ HPHP is available in three forms:

  • Cast solid in drums requiring a hot room or drum heater to melt the drum contents for removal.
  • Free-flowing nuggets in bags that have good resistance to caking.
  • Bulk molten shipped in tank trucks requiring a heated tank for storage.
