Excellent thermal stability and high temperature yellowing resistance, widely used in a variety of light color high temperature resistant coatings. Coatings made with Durle PES dispersion have higher gloss, lighter color and higher hardness.
Excellent flexibility and melt fluidity, can be mixed with Diller water-based PAI resin or PAI dispersion to prepare primer.
Excellent chemical resistance. Various coatings made with the PES have high resistance to salt water, salt spray, acid and alkali, and organic solvents.
It can be compatible with most waterborne emulsions and resins, can be diluted with deionized water directly, excellent compatibility and water dilution performance, can be directly made of single-layer coating.
