Abstract
Polyurethane-based anti-corrosion coatings has drawn a lot of attention in industry due to its superior anti-corrosion properties like its exemplary hardness and anti-abrasion. Although this material is very promising, there has been no formal analysis on its technologies stored in patent documents. This study navigates the diverse patent technologies by scrutinizing a dataset of 10,300 patents developed by 30 countries from 2001-2021. Graphs and chart are generated to see trends in categorized patent information. Cognitive networks are generated as well as the entropy and diversity of each of the patenting regions. Heat map locate gaps in technological development as well as highlight prolific patenting countries. China is the top player in terms of the number of published patents. Large chemical manufacturers like BASF coating from Germany and multinational steel corporation like the Nippon Steel Corp from Japan shows large interest on polyurethane-based anti-corrosion coatings.
