Application
heat sensitive 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
Water-based polyester resin
Application in saturated polyester coatings :
Excellent hardness with some flexibility
Has a very high glass transition temperature (Tg) compared to linear aliphatic diols
The hydroxyl group has high reactivity, and the reaction speed is fast and the reaction temperature is low during the resin synthesis and curing process.
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 glass fiber reinforced plastics have excellent corrosion resistance

Synthesis Tips
- A packed fractionator is required due to water solubility.
- meltedCHDM The contents of the container were mixed and agitated prior to sampling to ensure a homogeneous isomer mixture.
- Due to good thermal stability, even if the synthesis temperature is 230℃~240℃ A light colored resin is also available.
- Two primary hydroxyl groups provide good reactivity and moderate synthesis time.
- Esterification catalyst is not required but can be used.
