Lin Kai, Shanghai International, Haihong Laoren, Jordan, Kansai, PPGsigma (trial code), Sakura, KCC, Nanbao and other China marine coatings are generally monopolized by foreign companies: for example, PPGsigma is a German brand; Jordan is a joint venture between COSCO and Britain: Kansai is a joint venture between COSCO and Japan; Kcc is from Smecta, Korea, and Sakura and Nippon are from Japan. Shanghai Lin Kai is the only domestic brand, and its zinc-rich primer can do it. Personally, I think PPGsigma's paint is good. In the past, the ships built by shipowners for Dedan were all called PPG, and the paint of Jordan was compared with that of PPG. In terms of paint adhesion, PPG beat Jordan completely, and its appearance is not as good as Jordan's.
