Ultrafine powder coating: Smooth surface, dense structure and enhanced ...
The ultrafine powder coating panel demonstrates larger modulus of resistance at Hz (×10 10 Ω cm 2) than the coarse one (×10 10 Ω cm 2), and boarder plateau of phase angle close to −90° at high frequency domain, which indicate that ultrafine powder coatings have better barrier effect and corrosion protection for the steel than ...
