Low temperature drying paint of high hydroxy polyurethane

Low temperature drying paint of high hydroxy polyurethane

This  two-component  low-temperature  high-hydroxyl  water-based  paint  exhibits  excellent adhesion on plastic substrates including ABS, PC, PA, PC+ABS, and ABS+glass fiber. During assembly  line  production,  light  industrial  products  require  65°C  curing  for  30  minutes, followed by 2-4 hours of baking and cooling before proceeding to subsequent processes or packaging. The selection of compatible curing agents significantly impacts activation time and hardness attainment. Under ambient conditions, self-curing is influenced by temperature and humidity variations. When air humidity ≤ 70%, the paint typically takes 40-60 minutes to dry by touch and ≥ 24 hours to achieve full hardening. The complete self-curing timeline depends on  product   specifications   and   environmental   conditions.  Key   advantages:  Non-abrasive surface,   high   gloss/fullness,   superior   chemical   resistance,   excellent   recoatability,   high hardness, superior scratch resistance, and enhanced outdoor performance.
