application  
 Thermal primer resin
  Chemical and pharmaceutical intermediates
Cosmetic polymer intermediates
Polyester Polyols for Polyurethane Coatings
  Melamine (melamine) polyester baked porcelain
Solvents for Cosmetics and Personal Care
 Unsaturated polyester resin 
Waterborne polyester resin

  Application in saturated polyester coating  ：
    Excellent hardness with some flexibility
Very high glass transition temperature (Tg) relative to linear aliphatic diols
The hydroxyl group has high reactivity, and in the process of resin synthesis and curing, the reaction speed is fast and the reaction temperature is low.

 Application in unsaturated polyester resin products  ：
       Excellent heat resistance and electrical properties, especially for the synthesis of unsaturated polyester resin glass fiber reinforced sheet molding compound SMC.
Very high crystallinity can be used for granular injection molding.
Synthetic fiberglass reinforced plastic has excellent corrosion resistance

  Synthesis Tips

- A packed fractionation column is required due to water solubility.
- Melt the contents of the CHDM vessel and stir before taking the sample to ensure a homogeneous mixture of isomers.
- Due to good thermal stability, light-colored resin can be obtained even if the synthesis temperature is 230℃～240℃.
- Two primary hydroxyl groups provide good reactivity and moderate synthesis time.
- Does not require an esterification catalyst, but can also be used.
