Abstract
The reaction mechanisms and structure–performance correlations of polymers used in coatings can be used to derive coating performance and promote innovation of coatings, but they are scattered in references. The paper first summarizes them. There are four important rheological issues in coating industry: one-point rheological test, how to select coating components, how to control application process, and correlations of rheological methods to coating performance. The paper provides solutions to the issues based on rheological references. Since it is not easy to prepare qualified phosphate films, inorganic–organic hybrid coatings have been developed and applied on metal surface without phosphating film, but the hybrid coatings usually use a large amount of solvents. The paper proposes a way to prepare VOC-compliant hybrid coatings composed of tetraethoxysilane sol below its critical gelation point and liquid prepolymers by dual-cure.
期刊介绍：
"Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad.
"Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
