1,4-Cyclohexanedicarboxylic acid Usage
Resin for powder coating;Resin for coil coatings;Used medicinally for the synthesis of peptic
ulcer drugs;In polyester resin, as a modified monomer;High solids polyester – melamine baking
enamel;Gel coating with unsaturated polyester resin.In the application of waterborne
polyurethane resin: 1, 4 – CHDA and AD (adipic acid) has good workability, low solution
viscosity, PIA (phthalic acid) the next scattered Chemicalbook stability: 1, 4 – CHDA > PIA >
AD1, 4 – CHDA also can make the resin a good balance between hardness and flexibility, 1, 4 –
CHDA can be used to improve the dispersion of acrylic resin, as well as with good storage
stability.In addition, 1, 4-CHDA coordinated with acrylic resin better than resorcinic acid
(DOP).The reactivity of 1, 4-CHDA was higher than PIA
In medicine, used in the synthesis of peptic ulcer drugs; in polyester resin, used as a modified
monomer to improve the yellowing of polyester resin and its flexibility (softness) without
changing its hardness.

Uses of 1,4-Cyclohexanedicarboxylic acid
Resins for powder coatings; resins for coil coatings; used in medicine to synthesize peptic ulcer drugs; used as modified monomers in polyester resins; high-solid polyester-melamine baking enamel; gel coating Use unsaturated polyester resin. Application in waterborne polyurethane resin: 1,4-CHDA and AD (adipic acid) have better processability, lower solution viscosity, PIA (phthalic acid) is followed by dispersion stability: 1 ,4-CHDA>PIA>AD 1,4-CHDA can also make the resin achieve a good balance between hardness and flexibility 1,4-CHDA can be used to improve the dispersion of acrylic resin, and at the same time have good storage stability. In addition, the coordination of 1,4-CHDA and acrylic resin
In medicine, it is used to synthesize peptic ulcer drugs. In polyester resin, it is used as a modified monomer to improve the yellowing of polyester resin and improve its flexibility (softness) without changing its hardness.
