IntroductionCorrosion problems often start quietly: moisture reaches a steel surface, salts accelerate the reaction, and a coating that looked intact begins to blister, crack, or lose adhesion.
IntroductionPolyester polyol is valued for strength, adhesion, and chemical resistance, but formulators often face practical limits: moisture aging, hydrolysis, high viscosity, brittle performance, or unstable processing.
