Kouch poud Polyester montre bon rezistans move tan, severite, adezyon, ak bon nivelman ak plenite fim. Sepandan, lè l sèvi avèk kouch poud Polyester pou kont li pa ka pwodui penti poud anti-grafiti ak bon rezistans tach, kòm rezistans tach yo, rezistans sòlvan, ak enèji gratis sifas pa satisfè kondisyon yo pou kouch anti-grafiti. Chwa a nan polyester idroksil dirèkteman afekte pèfòmans nan anti-grafiti nan fim nan kouch; kouch ki fèt ak polyestè hydroxyl ak pi wo valè idroksil montre pi bon pèfòmans anti-grafiti.
According to the standard "Environmental Testing for Electrical and Electronic Products Part 2: Test Methods and Guidelines" (GB/T 2423.16-2008), mold growth tests can be conducted on polyester powder coatings. Test species include Aspergillus niger and Aspergillus terreus, with evaluation levels ranging from 0 to 3. Polyester/TGI and polyester/HAA powder coating sheets, under conditions of 28 days, humidity >90% RH, ak tanperati 28 degre, tou de te montre yon nivo kwasans mwazi nan 0 (pa gen mwazi).
