Application
Thermosensitive 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 products
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. During the resin synthesis and curing process, the reaction speed is fast and the reaction temperature is low.
Application in unsaturated polyester resin products :
Excellent heat resistance and electrical properties, especially used to synthesize 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
– Due to its water solubility, a packed segregation tower is required.
– MeltingCHDM The contents of the container are stirred before taking the sample to ensure a homogeneous mixture of isomers.
– Due to good thermal stability, even if the synthesis temperature is 230℃~240℃ Light-colored resins are also available.
– Two primary hydroxyl groups provide good reactivity and moderate synthesis time.
– Esterification catalyst is not required, but can be used.
