Polyester hmoov coatings pom zoo huab cua tsis kam, toughness, adhesion, thiab zoo leveling thiab film fullness. Txawm li cas los xij, siv polyester hmoov txheej ib leeg tsis tuaj yeem tsim cov tshuaj tiv thaiv - graffiti hmoov txheej nrog zoo stain tsis kam, vim lawv cov stain tsis kam, hnyav tsis kam, thiab lub zog tsis muaj zog tsis ua raws li cov kev cai rau kev tiv thaiv - graffiti coatings. Qhov kev xaiv ntawm hydroxyl polyester ncaj qha cuam tshuam rau kev tiv thaiv - graffiti kev ua tau zoo ntawm txheej zaj duab xis; coatings ua los ntawm hydroxyl polyesters nrog ntau dua hydroxyl qhov tseem ceeb qhia tau zoo dua los tiv thaiv -graffiti kev ua tau zoo.
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, thiab kub 28 degree, ob qho tib si pom cov pwm loj hlob ntawm 0 (tsis muaj pwm).
