Application

EASTMAN CHDM 1,4-cyclohexanedimethanol 105-08-8

                                                                               

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

Structure/Property Relationship

Structural features

Performance Characteristics

First-order and unhindered hydroxyl group

Polymer synthesis is very fast, and the temperature is lower or the time is reduced during cross-linking

Symmetric structure

Excellent thermal stability, light-colored resin

Saturated cyclic structure

Very good hardness and certain flexibility

1,4-Substitution structure

Very high glass transition temperature (Tg), medium solubility

β-position hydrogen

Medium weather 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.
