Usage:
1,4-cyclohexyl Alkanedimethanol is mainly used in polyester profiles, polyester fibers, and unsaturated polyester resins, such as PETG, PCT, PCTG, PCTA, etc., to enhance the reactivity of polyester compounds and improve the hydrolytic stability, plasticity, and gloss of polymers Degree, transparency, printability, processing ability. CHDM can also be used in coatings (powder coatings), which can improve the low temperature resistance and weather resistance of coatings, and improve gloss.
