因yin水shui性xing漆qi與yu油you性xing漆qi的de成cheng膜mo原yuan理li不bu同tong
，所suo以yi硬ying度du也ye不bu一yi樣yang。油you性xing漆qi因yin有you助zhu溶rong劑ji肯ken定ding比bi水shui揮hui發fa的de要yao快kuai，這zhe樣yang就jiu縮suo短duan了le它ta的de成cheng膜mo時shi間jian，所suo以yi硬ying度du上shang來lai就jiu快kuai一yi點dian。而er水shui性xing漆qi靠kao水shui揮hui發fa交jiao聯lian成cheng膜mo

，水shui揮hui發fa較jiao慢man而er且qie交jiao聯lian成cheng膜mo要yao有you一yi個ge過guo程cheng，這zhe樣yang就jiu需xu要yao時shi間jian來lai完wan成cheng所suo以yi硬ying度du起qi來lai及ji比bi較jiao緩huan慢man，一yi旦dan完wan成cheng成cheng膜mo
，硬ying度du就jiu能neng達da到dao油you性xing漆qi的de硬ying度du。
